Widely used with good effect, UV absorber, choose RIASORB® UV-P!

Star product recommendation |RIASORB® UV-P:Widely used with good effect

It is well known that polymer materials exposed to sunlight for a long time will be affected by ultraviolet light and cause photo-aging. The aging reaction will lead to material becoming discolored and lose parts of physical properties. And the material service life will be shortened.


The most commonly used solution to the photoaging problem of polymer materials is to add light stabilizers, including ultraviolet absorbers and blocked amine light stabilizers. RIASORB UV-P is one of the star UV absorbers.


1.Basic data


2.Product advantages

Wider UV absorption band

RIASORB UV-P as a benzotriazole UV absorber, compared with the other two kinds of UV absorbents itself has a wider UV absorption range.

Wider range of applications

RIASORB UV-P is suitable for most kinds of polymer materials, including styrene polymer materials such as ABS, MBS, HIPS, SAN, ASA, PC/ABS, PC/ASA, polymethyl methacrylate, POLYvinyl chloride, polyurethane, and a variety of engineering plastics.

RIASORB UV-P's UV absorption properties perfectly match the light-sensitive bands of these polymer materials


3.Application guidelines

Rianlon recommends the RIASORB UV-P dosage from 0.1-0.5%. At the same time, RIASORB UV-P is used in combination with other Rianlon hindered amines light stabilizers to further improve the light stability of the material. Below is an example of RIASORB UV-P combined with RIASORB UV-770. You can see the "1+1> 2 " effect.
