Tiangang® T-81 / T-70

High Performance light stabilizer System with Low VOC

Chemical name Proprietary blend
Tiangang® T-81 / T-70 is a high concentration UV light stabilizer blend loaded on polypropylene. It provides excellent protection to polymers, especially polypropylenes and TPO against UV light induced photo-degradations, as well as head degradations. It does not have observed “blooming” effect, and has low color contribution and volatility, which makes it ideal light stabilizer for applications such as PP/EPDM used in automotive interiors and exteriors. Its granular product form is easy to handle, and disperse.
Base Polymer Polypropylene
