First, the function of silicone masterbatch and application areas
1, silicone masterbatch function
Effectively improve the processing performance, high mixing rate, flow, filling, mold release to reduce the accumulation of die.
Significantly reduce the friction coefficient, improve the slipperiness, reduce processing energy consumption, improve production efficiency and extend processing equipment life.
Improve the dispersion of pigments and fillers, with good stability and non-migration.
Improve the melting rate and deformation of plastic effectively, reduce the viscosity, improve the plasticization, prevent the melt burst, improve the smoothness, gloss, touch and abrasion resistance, corrosion resistance, aging resistance and elongation increase of the plastic products And cantilever impact strength.
With the organic metal salt of magnesium stearate, ammonium polyphosphate, aluminum hydroxide, pentaerythritol mixture, etc., both with the substrate polymerization, but also with the silicone polymer synergistic reaction to improve the two polymer permeability Promote the formation of carbon layer, prevent the formation of smoke and flame development to achieve a good flame retardant effect.
Safety and environmental protection, in full compliance with EU environmental standards.
2, silicone masterbatch applications
It is widely used in thermoplastics such as PP, PE, EVA, EPDM, ABS, PA, PC, PBT, PPO, PPS and POM etc. It is widely used in modified plastic, halogen- Large injection molded parts, thin-walled shaped complex plastic parts, plastic pipe and other fields.
Usage: Silicone plastic additives and thermoplastic resin directly mixed in proportion, and then molding processing. In plastic processing, can be widely used as a flow promoter, anti-caking agents, flame retardants, lubricants, hydrophobic Such as: flame retardant synergist for polyethylene-aluminum hydroxide / magnesium halogen-free flame retardant system, general purpose Polystyrene impact modifiers and lubricants.
For polyolefin cable production not only has a good flame retardant effect, but also improve the gloss of the cable surface, feel, insulation and anti-aging properties.
For high-grade shoes, plastic shoes so that the end with ultra-high wear resistance and scratch resistance.
