SLK Series Silicone Additives for Plastics
Structure：
Made from ultra-high molecular weight polysiloxane
Traits：
SLK series silicone additives for plastics used by plastics as processing aids and impart expected silicone benefits to plastics, often more efficiently than lower molecular weight silicone fluids, such as safety,steady performance, little effect on the adhesion of paints, labels or decorations, more convenient to handle, good dispersion.
Functions：
Improve therm plastic resins melt fluidity, shorten mold cycle time, lower machine wear.
．Better internal lubricate and mould release, speed throughput, lessen deformation and product rejection rate.
．Meliorate the compatibility between resin and other stuffings.
．Lower coefficient of friction obviously, be more lubricious and greater mar and abrasion resistance.
．Improve fire retardant properties, lower smoke rate, heat and carbon monoxide during production.
．Heighten products' surface smoothness and touch.
．Amend products' stretching and impact strength.

Packing, storage, transportation:
Usually inner packing is polythene film bag, outer package is polypropylene weave bag, 20KGS each bag. When stored in the dry environment at or below 35℃ in the original unopened package, it has a usable life of 48 months from the date of production. It can be transported expediently and easily as none-dangerous goods.
Usage
It should be blended with virgin polymer pellets to give the desired siloxane level in the final product. It can be added during compounding in a single screw extruder or added at the feed hopper during injection molding or extrusion.
