Silicone Masterbatch 



MB4110 is a pelletized formulation with 50% ultra high molecular weight siloxane polymer dispersed in High impact polystyrene (HIPS). It is widely used as an efficient additive for PS 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 ...

Fundamental Parameters

Grade                                                     MB4110

Appearance                                                White pellet

Silicone  content                     %                     50

Resin  base                                                HIPS

Melt index ( 200℃, 2.16KG )           g/10min              13 ( typical value )

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 storage.
