DOWSIL™ Si Powder Resin Modifiers are halogen-free powdered siloxanes recommended as processing aids in highly filled thermoplastic formulations such as halogen free flame-retardant wire and cable, window profiles, pipes, etc. Benefits observed include reduced die drool and torque, increased/maintained impact and tensile strength, lower water absorption, improved scratch and mar, higher LOI, and lower heat release rate, smoke, and rate of toxic gas evolution.

DOWSIL™ Si Powder Resin Modifiers are 100% active, halogen-free, siloxane powders. They are available with either methacrylate functionality or no additional organo-reactivity. The organic reactivity controls the compatibility, and, often, the performance of DOWSIL™ Si Powder Resin Modifiers in selected plastic applications.
