。Application

1. Polymerization of styrene

LQ-CH335 can be utilized to increase polymerization rates at temperatures between 90℃ and 120℃.

2. Other applications

LQ-CH335-B90 can also be used for the (co)polymerization of styrene, acrylonitrile, acrylates and methacrylates in the temperature range between 90℃ and 120℃.

3. Rubber crosslinking

Rubber compounds containing LQ-CH335 have excellent scorch safety.
