Application:
UV-3638 can be readily incorporated in the polymers within the dosage range of 0.1-10% by weight through conventional techniquire such as powder, solution, or melt blending(e.g. extrusion compounding). It can be used alone or in a variety of blends and combinations with antioxidants, phosphites and other light stabilizers where often a synergistic performance is observed. Basically, the dosage level for UV-3638 can be expectd to be 1/3 of the exsited benzotriazole type UV absorbers with the nearly same efficency of UV screenning.
Engineering plastics (Nylone/plycarbonate/PET/PBT/PPO/PPS..etc)
Because of it's superior heat resistance, so its volatility is extremely low during the processing of engineering plastics at temperatures above 300°C. Also, it offering a very strong & broad UV absorption with no color contribution and exllent stabilzation. so it will allow the recycling or reworking of scrap without significant lowss of the UV light stability. UV-3638 meets the stringent requirement of applications where light transmission and optical properties are critical.
Other polymers
Because of its high absorptivity in the range of 300-360nm, plus its extremely low volatility, assures maximal resistance to UV light degradation even during long term indoor and out door exposure.
