Introduction :

LT-622 is the low volatility and minimal migration , because of its oligomeric structure with high molecular weight. Furthermore LT-622 is effective as antioxidant and contributes significantly to the long term heat stability of polyolefins and tackifier resins.

Application :

LT-622 areas of application include polyolefins(PP , PE) , olefin copolymers such as EVA as well as blends of polypropylene with elastomers. In addition LT-622 is highly effective in polyacetals , polyamides and polyurethane applications.

The effectiveness of LT-622 surpasses significantly that of UV absorbers ,  particularly in pigmented systems.


Package: 25kg carton or paper barrel(PE plastic inside)
