Frequently Asked Questions — Polymer Production

Our organic peroxides, azo initiators, and polymer agents initiate and control polymerization for PVC, polyolefins, FRP, and acrylic systems. See the Polymer Production market page for application detail.

Match the initiator 10-hour half-life temperature to your processing temperature, then tune loading for target molecular weight and cure rate. Our Product Selector Tool and technical team guide the choice.

Store in a cool, well-ventilated area (many grades require refrigeration) away from heat and incompatibles, using PPE per the SDS. Full safety guidance and SDS ship with every order.
