。Safety and handling
Keep away from open fire, sparks and other sources of heat or ignition. Avoid contact with
reducing agents (e.g. amines), acids, alkalis and heavy metal compounds (e.g. accelerators,
driers and metal soaps). Please refer to the Safety Data Sheet (SDS) for further information
on the safe storage, use and handling of LQ-CH335-B90. This information should be thoroughly
reviewed prior to acceptance of this product.
。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.
