  Application of silicone masterbatch in modified plastics
  First, the function of silicone masterbatch
  1. Effectively improve processing performance, high mixing rate, activity, mold filling, mold release, reduce die head accumulation.
  2. Significantly reduce friction coefficient, improve slip, reduce processing energy consumption, improve production capacity, extend the service life of processing equipment.
  3. Improve the dispersion of the makeup filler, with good stability and non-migration.
  4. Effectively improve melting rate and deformation, reduce viscosity, improve plasticization, and prevent melt burst. Improve the lubrication, gloss, touch and wear resistance, corrosion resistance and aging resistance of plastic products, and increase the elongation and impact strength of suspended beams.
  5. Mixed with organometallic salt magnesium stearate, ammonium polyphosphate, aluminum hydroxide and pentaerythritol, it can not only polymerization with the substrate, but also synergistic reaction with silicone polymer, improve the interpermeability of the two polymers, promote the formation of carbon layer, hinder the composition of smoke and the development of flame, and achieve good flame retardant effect.
  6. Safety and environmental protection, fully in line with EU environmental standards.
  Application fields and methods of silicone masterbatch
  Suitable for PP, PE, EVA, EPDM, ABS, PA, PC, PBT, PPO, PPS, POM and other thermoplastics. It is widely used in modified plastics, halogen-free flame retardant cables, advanced soles, plastic insulation seals, large injection moulded parts, thin-walled chaotic plastic parts, plastic pipes and other fields.
  Usage: The silicone plastic additives and thermoplastic resin are directly mixed evenly in proportion, and then formed and processed. In plastic processing, it can be widely used as activity accelerator, anti-caking agent, synergistic flame retardant, lubricant, hydrophobic agent, release agent and so on. Thus improving impact resistance, lubrication, dispersion and flame retardant. For example: used as a flame retardant aid for polyethylene-aluminum hydroxide/magnesium halogen-free flame retardant systems, impact modifiers and lubricants for general polystyrene.
  The production of polyolefin cable not only has good flame retardant effect, but also can improve the appearance of the cable gloss, feel, insulation and aging resistance.
