Technical Specifications of Hindered Amine Light Stabilizer 770

The following are the technical specification requirements for hindered amine light stabilizer 770, from the perspective of Beijing Tiangang Auxiliary:

Hindered amine light stabilizer 770 is an important product of Beijing Tiangang Auxiliary. It is a high-efficiency light stabilizer widely used in plastics, rubber, coatings, and other fields. To ensure product quality and performance, we have established the following technical requirements.

1. Appearance: white to pale-yellow crystals

The appearance of HALS 770 shall be white to pale-yellow crystals, with uniform color and free of impurities.

2. Melting point: ≥146℃

The melting point of HALS 770 shall be greater than or equal to 146℃, to ensure it fully melts during processing and exhibits good thermal stability.

3. Assay: ≥99.5%

The assay of HALS 770 shall be greater than or equal to 99.5%, to ensure high purity and stability that meet our customers' processing and application requirements.

4. Moisture: ≤0.5%

The moisture content of HALS 770 shall be less than or equal to 0.5%, to ensure good drying properties that will not affect product quality and stability.

5. Ash content: ≤0.1%

The ash content of HALS 770 shall be less than or equal to 0.1%, to ensure high purity and stability while meeting our customers' processing and application requirements.

6. Heat resistance: ≥240℃

The heat resistance of HALS 770 shall be greater than or equal to 240℃, to ensure stability under high-temperature conditions without decomposition or the generation of hazardous substances, meeting our customers' processing and application requirements.

7. Hygroscopicity: ≤0.5%

The hygroscopicity of HALS 770 shall be less than or equal to 0.5%, to ensure strong water-repellent properties that will not affect product quality and stability due to moisture absorption.

Through the establishment of these technical requirements, we can ensure the quality and stability of hindered amine light stabilizer 770 and meet our customers' processing and application requirements. At the same time, we will continuously improve our production processes and quality-control measures to provide our customers with higher-quality, more stable products.
