Silicone Masterbatch RJ-S104

RJ-S104 is ultra-high molecular weight polysiloxane dispersed in Thermoplastic Polyurethane. It is widely used as an additive in resin compatible system to improve processing properties and surface quality. With RJ-104, properties like liquidity, de-molding, dispersion are highly improved. Meanwhile, the coefficient of friction is lowered and surface become smoother, thereby improving anti-friction properties, scratch and abrasion resistance.

Thermoplastic Polyurethane

This product can be used in variety of applications, including:
Due to its standard particle form, RJ-S104 can improve thermoplastic polyurethane\'s properties in many aspects as an additive:
  • It is suitable for directly injection molding, extrusion, and blown film after mixing with the plastic particles.
  • It can obviously improve the processing fluidity, reduce torque and enhance throughput.
  • It can enhance surface smoothness and improve the mold filling ability and de-molding properties when injection molding.
  • It can also enhance surface gloss and reduce die drool.
  • With low migration and no exudation, RJ-S104 will not affect printing and coating properties.
  • RJ-S104 can be used with all known additives, used together with fillers can promote the dispersion of fillers.
  • RJ-S104 can used as the food contact additive, the polyolefin part of RJ-S104 is compliance with article 177.1520(c)3 of FDA, siloxane part is compliance with 181.28 of FDA.
According to state and international transportation regulation, RJ-S104 is not a dangerous product.| The standard packaging is craft paper bag, 25kg/bag net weight.| For other quantitative packaging availability, please contact our marketing representat
