保定紫外线吸收剂厂

PVC紫外线吸收剂主要用途：

PVC ultraviolet absorbent main use:

PVC紫外线吸收剂适用于涂料、橡胶、油品等其他需要屏蔽荧光的场合；PVC紫外线吸收剂特别适用于无色透明和浅色制品中。

PVC UV absorbers are suitable for other occasions such as paint, rubber, oil and other situations that need to be screened for fluorescence; PVC UV absorbers are especially suitable for colorless transparent and light colored products.

二. 突出特点：

Two. Outstanding characteristics:

PVC紫外线吸收剂超强的荧光屏蔽效果，大大降低荧光强度、荧光级别；有效降低荧光所带来的各种危害性，大幅度提高产品的抗老化性能。色浅，为无色透明和浅色制品的首选荧光消除剂；PVC紫外线吸收剂不易燃、不腐蚀、贮存稳定性好；PVC紫外线吸收剂与大多数体系相容性良好，兼具长效抗氧、抗黄变作用性能，可与一般抗氧剂并用；极高的安全性。

The ultra strong fluorescent shielding effect of PVC UV absorbers greatly reduces the fluorescence intensity and fluorescence level, effectively reduces the various hazards caused by the fluorescence, and greatly improves the anti-aging performance of the products. Light color, the first fluorescence elimination agent for colorless transparent and light color products; PVC UV Absorbents are not flammable, non corrosive, and good storage stability; PVC UV absorbers have good compatibility with most systems. They have long effective anti oxygen and yellowing properties, and can be used with the general antioxidant and high safety.
