PEarlene silicone gum containing masterbatches provide improved processability (extrusion rate, mold fill and power consumption) and performance (mar and scratch resistance) when used to compound or extrude certain plastics, copolymers or elastomeric formulations.

PEarlene silicone gum masterbatches are a family of functional masterbatches containing high levels of ultra- high- molecular- weight polysiloxane which are melt compounded into a thermoplastic polymer.

Typical usage levels are from 0.2% to 1.6% by weight of silicone gum.
The product line consists of several silicone gum masterbatches based on polyolefins (PE and PP) as well as PC.

Polymer Modification:
PEarlene SiPP MB-05 silicone (PP: polypropylene homopolymer)

These masterbatches modify the rheological characteristics of the resin or compound, which may allow for increased throughput in fabrication operations as well as reduction in drive torque and machine head pressure. These masterbatches are typically used at 0.2 to 1.6 % by weight of silicone gum.
