Chinaplas 2019: Tiangang Showcases HS-625 and XT-8 Light Stabilizers
On April 9, 2019, the 33rd China International Exhibition on Plastics and Rubber Industries (Chinaplas 2019) opened to great anticipation. As the plastics and rubber industry's headline event of the year, leading enterprises from across the global supply chain gathered in Guangzhou to showcase cutting-edge technologies and discuss the industry's future. As a major international plastics event held in China, Chinaplas 2019 undoubtedly gave Chinese plastics enterprises a window onto the world and a stage to display the strength of national brands. In recent years, as domestic enterprises have sharpened their innovation awareness, Chinese plastics companies have made remarkable progress — many have reached international standards and entered global markets, and Beijing Tiangang Auxiliary Co., Ltd. is among them. During the show, the HC Plastic Network team visited the Tiangang booth, and Liu Gang, Deputy General Manager of Beijing Tiangang Auxiliary Co., Ltd. (referred to as 'Mr. Liu' below), gave an exclusive interview to HC Plastic Network.

About Beijing Tiangang Auxiliary Co., Ltd.
Beijing Tiangang Auxiliary Co., Ltd. is a national-level high-tech enterprise focused on R&D and manufacturing of high-performance polymer additives, and one of China's earliest professional developers and producers of anti-aging functional materials. As a technology-driven manufacturer, Tiangang places great emphasis on product quality and technological innovation. Not only have its main products reached internationally advanced performance levels, but the company has also sustained long-term investment in technology and R&D, continuously filling multiple domestic gaps, and holds multiple proprietary products and invention patents. Tiangang enjoys a strong reputation in both domestic and international markets and leads in key segments; its products are exported to major countries and regions including Europe, North America and Asia, and are selected by numerous internationally renowned companies.
Two Swords Unsheathed: Tiangang Empowers Its Products with Innovation
As a familiar participant at Chinaplas, Tiangang has let attending enterprises from around the world witness its innovation strength on several occasions. According to Mr. Liu, Tiangang highlighted two signature products at this show — the high-molecular-weight hindered-amine light stabilizer Tiangang® HS-625 and Tiangang® XT-8 — both proprietary, self-developed products and symbols of Tiangang's technological innovation.
These two products indeed have impressive credentials. As Mr. Liu stated in the interview: 'These two products were granted the world's only chemical structure codes issued by the American Chemical Society — the commonly known CAS Registry Numbers — becoming new members of the world's chemical-structure family. Even more gratifying, these two new high-molecular-weight hindered-amine light stabilizers also obtained European REACH registration and U.S. TSCA registration simultaneously, opening the door for China-original polymeric light stabilizers to reach the world.' According to HC Plastic Network, these two products are the fruit of nearly a decade of R&D by the Tiangang team, tested over the long term in the Chinese market, and serve as important next-generation replacements for traditional high-molecular-weight hindered-amine light stabilizers such as 944, which foreign companies successfully developed back in the 1970s. On this, Mr. Liu said: Tiangang's two products are not merely substitutes for traditional ones, but upgrades — we have endowed the products with even more advantages.

Let us take a first look at the characteristics of these two products
Tiangang® HS-625:
It features low basicity, high molecular weight and high efficiency, and is especially suitable for harsh environments with some acidic influence, such as agricultural greenhouse film, artificial turf, solar films, floating aquatic structures and ropes/cables;
Tiangang® XT-8:
It is a high-molecular-weight N-OR structured light stabilizer representing internationally advanced levels, and has received high praise in the market.
Tiangang's participation featured a strong lineup of Tiangang plus Tainaco New Materials. As Tiangang's nano-technology enterprise, Tainaco New Materials also presented excellent products, highlighting two series this time: the nylon-specific reinforcement masterbatch series and the Tinabio anti-mold and antibacterial product series. On Tainaco's exhibits, Mr. Liu said: Tainaco's products are of epoch-making significance, as its slogan says, 'Creating New Possibilities for Plastics.'
Nylon-specific reinforcement masterbatch series:
By simply blending it into PA6, it can substantially improve resin properties, nearly reaching PA66 performance. For downstream enterprises suffering from high PA66 prices, this is perfectly timed;
Tinabio anti-mold and antibacterial product series:
At extremely low addition levels, it enables materials to achieve 0-grade mold resistance and highly efficient antibacterial and anti-algae performance — something almost impossible with traditional anti-mold and antibacterial products.
Innovation Investment Creates Future Products
'Technological innovation and independent R&D' has always been Tiangang's development philosophy for taking root in the industry, and over the years has become its winning formula.
Tiangang has long been deeply engaged in the field of light stabilizers, with independent innovation as its R&D approach and customer needs as its guide, persistently enabling materials to achieve longer service life at lower cost, to adapt more easily to more demanding environments, and to respond faster to customers' formulation needs. Tiangang spares no effort in R&D investment, and it is precisely this commitment that achieved the outstanding result of products obtaining CAS numbers — and it continues today. It is understood that in Tiangang's laboratories there are several more new products of epoch-making significance that will be launched in the coming years.
In the field of targeted nano-technology, Tainaco New Materials has realized multiple research achievements and focused its future R&D direction on the high-performance upgrading of a few materials such as nylon, polypropylene and polyvinyl chloride, as well as on the two main directions of anti-mold, antibacterial and antiviral preservation of materials — advancing industrial development with the power of science and technology and creating new possibilities for materials.
On this, Mr. Liu said: Whether in the field of light stabilizers or targeted nano-technology, Tiangang's path of innovation will not only remain unchanged, but will shine even more brightly.
Core Independent-R&D Strength Drives Tiangang's High-Speed Growth
Today's market demand is changing rapidly, so how to quickly capture market needs and how to rapidly and accurately provide customers with the materials or products they need has become an important means for enterprises to win the market; one solution is efficiency in R&D. As a professional anti-aging technology and product service provider in the plastics materials field, the R&D system Tiangang has built up over the years supports its current market layout, enabling rapid assistance to customers in formulation screening and optimization, meeting customers' rising service-life requirements at the most reasonable cost — and it is precisely this efficiency that has realized Tiangang's high-speed growth. On this, Mr. Liu said: Tiangang's 2019 sales performance was very strong; despite some traditional markets tending toward saturation with slowing growth, and a 10% tariff imposed on some products amid the China-U.S. trade war, by deeply tapping market potential, expanding application fields and exploring new markets, Tiangang maintained rapid high double-digit growth — especially its uniquely structured chemical products achieved very encouraging growth. We expect traditional-market growth to continue slowing, while 'blue ocean' markets developed through efficient R&D will keep emerging. Therefore, Tiangang will continue along the path of independent R&D, persistent innovation and strengthened service.
As the saying goes, 'One must have a passion to achieve success,' and Tiangang's success proves this truth — passionate about innovation and R&D, it has earned today's market recognition.
