Description

Tinuvin 234, also known as light stabilizer 234, is a high-molecular-weight hydroxyphenylbenzotriazole UV absorber, which has excellent light stability for a large number of polymers. Tinuvin 234 has the characteristics of migration resistance, heat resistance, low volatility, good compatibility, strong UV absorption, etc., and has almost no effect on product color. Tinuvin 234 is especially suitable for polymers that need to be processed at high temperatures and low loss. It is widely used in polycarbonate, polyester, polyacetal, polyacetal, polyamide, polyphenylene ether, polyphenylene sulfide, aromatic copolymers, Polyphenylene oxide, linear polyester, thermoplastic polyurethane, polyurethane fiber and materials such as polyvinyl chloride, styrene copolymer and homopolymer, it is also suitable for mold products, films, sheets and fibers and other products. Tinuvin 234 is licensed for food contact in many polymer applications. It is particularly suitable for food contact packaging materials, health products, and pharmaceutical products. Tinuvin 234 protects packaging materials from the harmful effects of ultraviolet radiation.

Advantage

Tinuvin 234 is light in color and hardly affects the color of the product.

Tinuvin 234 has excellent high temperature resistance, and is especially suitable for processing under high temperature conditions.

Tinuvin 234 has low volatility and high resistance to thermal degradation in olefin compounding and molding applications.

Tinuvin 234 can be used alone or in combination with other additives (light stabilizers, antioxidants) to enhance weather resistance.

Recommended dosage

Coating: 1~3%

Polycarbonate: 0.2~0.4%

Acrylic: 0.1~0.3%

Polyester: 0.1~0.3%

In outdoor products, it can be used together with phenolic antioxidants and phosphite antioxidants

Packaging

25kg/carton

Storage

Avoid sunlight, high temperature and humidity, and avoid light stabilizers containing sulfur or halogen elements. Tinuvin 234 needs to be stored in a dry, dark place.
