LYSI -406

Technical Datasheet | Supplied by DKSH
LYSI-406 distributed by DKSH is siloxane polymer masterbatch. This is a pelletized formulation with 50% ultra-high molecular weight siloxane polymer dispersed in polypropylene (PP). It is widely used as an efficient additive for PP compatible resin system. It improves the processing properties and surface quality such as surface slip, better resin flow ability, mold filling & release, less extruder torque, lower coefficient of friction, greater mar, scratch and abrasion resistance. The dosage level of LYSI-406 is 0.5-5% (w/w). It is used in classical melt blending process like single/twin screw extruders and injection molding. The shelf life of this additive is 24 months.
