Silicone Masterbatch



MB4112 is a pelletized formulation with 50% ultra high molecular weight siloxane polymer dispersed in Linear low density polyethylene (LLDPE). It is widely used as an efficient additive for PE compatible resin system to improve the processing properties and surface quality, such as better resin flow ability , mold filling & release, less extruder torque , lower coefficient of friction , greater mar and abrasion resistance ...

Dosage                             % (w/w)                0.5~5


Improve processing properties including better flow ability , reduced extrusion die drool , less extruder torque , better molding filling & release

Improve surface quality like surface slip, lower Coefficient of friction, Greater abrasion & scratch resistance

Faster throughput , reduce product defect rate.

Enhance stability compare with traditional processing aid or lubricants  


How to use  

Addition levels between 0.5~5.0% are suggested . It can be used in classical melt blending process like Single /Twin screw extruders, injection molding. A physical blend with virgin polymer pellets is recommended .


25Kg / bag , craft paper bag


Transport as non-hazardous chemical. Store in a cool , well ventilated place .

Shelf life

Original characteristics remain intact for 24 months from the production date , if kept in recommend st
