Standards, Patents and Industry Contributions

Participating in rule-making, joining industry organizations and driving technological progress - these things do not appear in product brochures, but they determine how far an enterprise can go. This page describes Tiangang's role in these areas.

Additives are a classic "invisible supporting" industry: customers buy materials, while additive manufacturers sell the service life behind the materials. For this very reason,whoever participates in rule-making knows earlier where the rules are heading. The specific positions Tiangang holds in standardization organizations are what this page sets out to explain.

Fine production line of a modern chemical enterprise

R&D investment must ultimately translate into deliverable industrial products - which is also why standards and patents exist

1. Tiangang's platform qualificationsQualifications & Platforms

Tiangang's qualifications are not about "holding many certificates", but rathereach one maps directly to a mandatory question in the customer's audit questionnaire. The table below is arranged on that basis.

Category	Tiangang's qualification / platform	Role in customer audits
Enterprise qualifications	National-level high-tech enterprise National-level specialized, refined, distinctive and innovative (SRDI) "little giant" enterprise Beijing municipal SRDI "little giant" enterprise	The SRDI "little giant" designation is conferred by the Ministry of Industry and Information Technology; the national selection ratio is low, and it is an official recognition of technical capability and specialization in a niche field
Technology platforms	China National Light Industry Council Plastic Products Weather Resistance Engineering Technology Research Center China Plastic Products Weather Resistance Technology Laboratory Beijing (provincial-level) enterprise technology center	The first two are accredited by the China National Light Industry Council and the China Plastics Processing Industry Association respectively; together with the CNAS testing center they form a "R&D + testing + standards" trinity technical system
Testing qualifications	China National Accreditation Service for Conformity Assessment (CNAS) accredited laboratory	Accepted by more than 100 economies under the ILAC-MRA framework, it is the most quantifiable trust credential in customer factory audits and export certification
Enterprise honors	Beijing Top 100 Socially Responsible Enterprises	A scoring plus in ESG audits by central and state-owned enterprises and large end customers

Tiangang's reminder on supplier audits: these qualifications are not decoration. In customers' supplier audit questionnaires,"whether you hold CNAS accreditation" and "whether you have a national-level technology center" are usually mandatory questions rather than bonus points. Missing any one of them may put you directly outside the supplier list - this is what Tiangang recommends new customers verify at first contact.

2. Awards received by TiangangAwards

Award	Level	Tiangang's awarded project / description
Ministry of Education "Science and Technology Progress First Prize"	National level	The highest honor for science and technology awards in China's education field
China National Light Industry Council Science and Technology Progress Award	Ministerial level (two awards)
China Plastics Processing Industry "13th Five-Year Plan" Outstanding Scientific and Technological Achievement	Industry level
China Society of Agro-Applied Plastics Technology Product Innovation Award	Industry level
China International Engineering Plastics Industry Innovation Additive Award	Industry level
Ringier Technology Innovation Award	Industry level	2023 - application results of HS-950 in HDPE for floating PV floats
Provincial/ministerial-level Science and Technology Progress Award	Ministerial level	HS-625 polymeric HALS light stabilizer

On the significance of the Ringier Technology Innovation Award

This award deserves separate explanation. Tiangang's products are used inHDPE for floating PV floats, with expected service life improving from the industry-typical 3-5 yearsto 10-20 years. It answers two questions at once: first, whether it can be done (the service-life data), and second, who has verified it (an award from an independent third-party media organization).

For materials companies that need to account for service-life responsibility to end owners, insurers or investors, a service-life figure backed by a third party is far more persuasive than any internal test report. This is also why Tiangang is willing to push this application into industry awards - not to win a prize, but to give downstream customers a basis they can write into a warranty contract.

Why Tiangang chose this case: floating PV floats represent one of the "extreme operating conditions" for weather-resistance technology - HDPE is immersed in water long term, reflected sunlight raises UV intensity above conventional ground levels, day-night temperature cycling is severe, and once a float cracks, maintenance on the water surface is extremely difficult.Achieving a 10-20 year service life under such conditions itself demonstrates the robustness of the system design.

3. Standards Tiangang has participated in formulatingStandards Development

Tiangang has participated in formulating multiple national and industry standards related to material aging. The real value of this lies not in the honor but in three points - all three of which Tiangang uses every day.

Value	What it means for Tiangang
Anticipating technology directions	The process of setting standards is the process by which the industry forms consensus on technology trends. Tiangang's participation means knowing earlier how the evaluation system will change over the next 3-5 years - which directly determines how Tiangang's product roadmap is arranged
Influencing test protocols	The way a test standard is defined directly affects how customers evaluate products. For example, the GB/T 16422 series (plastics xenon-arc) and the GB/T 23987 series (coatings xenon-arc) are two different systems; choosing the wrong standard invalidates the test conclusions. Tiangang confirms this with customers before they place a test order
Customer trust built in advance	"Participation in standard-setting" is a clearly targeted qualification in supplier audits; the implicit message is that Tiangang understands the technical logic behind the evaluation system, rather than just reciting standard numbers

Specific positions Tiangang holds in standardization organizations:

Organization	Tiangang's position	Why this position matters
Aging Methods Subcommittee of the National Technical Committee for Plastic Standardization	Committee member	Sitting directly where the rules of "how aging is measured" are made
China Plastics Processing Industry Association	Vice-chairman unit	Discourse power at the industry association level
Agricultural Film Specialized Committee of the China Plastics Processing Industry Association	Deputy director unit	Agricultural film is the main downstream market for Tiangang's additive packages (T-68 / T-66 / T-69)
Plastic Additives Specialized Committee of the China Plastics Processing Industry Association	Deputy director unit	Sitting directly where the rules of "how additives are evaluated" are made
China Society of Agro-Applied Plastics Technology	Vice-chairman unit	A technical feedback channel at the agricultural film application end
China Productivity Promotion Center Association	Vice-chairman unit
China Synthetic Resin Association	Council member unit
Coatings and Painting Specialized Committee of the Chemical Industry and Engineering Society of China	Member unit	Coatings are an important application field for UV absorbers
Society of the Plastics Industry (SPI), USA	Member unit	Tiangang^® series are sold in more than 20 countries and regions, requiring participation in discussions of international market rules

Depth of Tiangang's standardization participation: serving as a committee member of the Aging Methods Subcommittee and as deputy director of the Plastic Additives Specialized Committee - these two positions are worth more than ordinary council member units -because they sit directly where the rules of "how aging is measured" and "how additives are evaluated" are made.Tiangang's participation in standards is not a nominal title, which explains why Tiangang can remind customers of standard version switches before they run tests (for example, GB/T 23987.2-2026 will take effect on 2027-02-01).

4. Tiangang's patents, technical publications and talent developmentPatents & Publications

Category	Tiangang's situation	Meaning for customers
Invention patents	Holds dozens of domestic and international invention patents	When a customer's needs run into someone else's patent barriers, Tiangang has usable alternative paths
Representative patent directions	N-alkoxy (NOR) hindered amine structure synthesis and purification; preparation of polymeric high-molecular-weight light stabilizers; low-acid halogen-free flame retardants and synergistic stabilization systems; anti-aging compound masterbatch technology	XT-8's original CAS structure and FR-810A's NOP™ patent both originate from these lines
Technical publications	Has published multiple books and articles on material aging and anti-aging technology	It shows Tiangang has accumulated enough time on this technology route to systematically organize experience into methodology, rather than just a pile of scattered experience
Standard-setting	Has participated in formulating multiple national and industry standards in the field of material aging
Talent development	Trains engineering and technical personnel in the field of aging and anti-aging technology; builds a talent pipeline relying on the enterprise technology center and CNAS testing center	Tiangang's technical service capability does not depend on any one individual - something customers look at when assessing long-term cooperation stability

"Publishing books" is relatively rare in the additives industry. It shows Tiangang has accumulated enough time on this technology route to systematically organize experience into methodology.

Why customers care about patents, from Tiangang's perspective: what customers really focus on regarding patents:Customers do not really care how many patents there are; what they really care about is - when my needs run into a patent barrier, can you give me a usable alternative path.This is also why Tiangang has both proprietary IP products and joint-venture technology introduction channels - the ability to do it ourselves and the channels to bring it in, with both routes open.

5. Tiangang's international footprint and technical cooperationInternational Presence

Tianji Clariant Chemical Additives (Cangzhou) is a 50/50 joint venture with Clariant Plastic & Coatings.

Entity / platform	Tiangang's positioning	Value to customers
Tianji Clariant Chemical Additives (Cangzhou) Co., Ltd.	A 50/50 joint venture with Clariant Plastic & Coatings (Switzerland), a global top-50 fine chemicals company; commissioned in 2021 with an annual capacity of 2,000 tons of polymer additives; in 2024, the environmental impact assessment for a 1,300-ton annual light stabilizer expansion project was approved	Access to the international technology system while retaining local rapid-response capability
Tiangang Chemicals Europe B.V.	Located in Brussels, Belgium; responsible for technology R&D, service and marketing	Localized service and compliance response for European customers, without crossing time zones every time
Tiangang^® series	Sold in more than 20 countries and regions worldwide, serving numerous internationally renowned companies	A practical test of international customers' confidence in product consistency

The strategic significance of the joint venture with Clariant is much greater than "having a joint-venture plant". Clariant's technology route in China is a dual track of "technology licensing + localized production" - on one hand placing high-value-added products into production within the Tiangang system to supply the Asia-Pacific market, and on the other introducing the global technology system through the joint-venture channel.Tiangang has thus gained an access point to international technology while preserving the independence of its own R&D and the speed of customer response.

The ultimate test of R&D capability is whether credible data can be produced at the customer's site. This is also why Tiangang places the CNAS testing center, the outdoor exposure base and the four-tier R&D platform in the same organizational structure - they are not three separate things, but one closed loop.
