Introduction:1.the uv stabilizer highly ensure good color consistency of plastic polymers in direct sunshine
2. absorbing the UV radiation and preventing the formation of free radicals
1. It is a light stabilizer with good performance, capable of absorbing the UV radiation of240-340 nm wavelength with the characteristics of light color, It can protect the polymer to its maximum extent, helps to reduce the color. 2. It can also delay the yellowing and obstacle the loss of its physical function.
Adding A-438 when mixing , first mix the plastic raw material even with diffusion agent or white mineral oil, then mix them for 8-10 minutes, after fully mixed, roasted material .then it can be used for extrusion, injection molding or blow molding.
