- This ester peroxide compound is a new type of initiator used for the aqueous suspension polymerization of vinyl chloride. When combined with LQ-CUPN (Cumyl peroxyneodecanoate) and LQ-LPO (Lauroyl peroxide), it enhances reactivity, working efficiently within a polymerization temperature range of 40-65°C.
- It also serves as a curing agent for unsaturated polyesters, particularly for high-end products requiring a wide temperature range. When combined with LQ-TBPB and LQ-CH335, it offers superior curing properties.
