Analysis of the application of silicone masterbatch in modified plastics

1, the function of silicone masterbatch

It can effectively improve the processing performance, high mixing rate, flow, filling, and demoulding to reduce die accumulation.

Significantly reduce the friction coefficient, improve the slipperiness, reduce the processing energy consumption, improve the production efficiency, and extend the service life of the processing equipment.

Improve the dispersibility of pigments and fillers, with good stability and non-migration.

Effectively increase the melting rate and deformability of plastics, reduce viscosity and improve plasticization to prevent melt bursting. Improve the smoothness, gloss, touch and abrasion resistance, corrosion resistance, aging resistance of plastic products, increase elongation and cantilever impact strength.

Blending with an organic metal salt of magnesium stearate, ammonium polyphosphate, aluminum hydroxide, pentaerythritol, etc., can be polymerized with the substrate and synergistically reacted with the silicone polymer to improve the mutual permeability of the two polymers. Promote the formation of carbon layer, prevent the formation of smoke and the development of flame to achieve a good flame retardant effect.

Safe and environmentally friendly, fully in line with EU environmental standards.

2. Application fields of silicone masterbatch

Suitable for thermoplastics such as PP, PE, ABS, PA, PC, PBT, EVA, PPO, PPS and POM. Widely used in modified plastics, large injection molded parts, plastic pipes, plastic insulation seals and plastic parts.

Method of use: The silicone plastic auxiliaries are directly mixed with the thermoplastic resin in proportion, and then subjected to molding processing. In plastic processing, it can be widely used as flow promoter, anti-caking agent, synergistic flame retardant, lubricant, hydrophobic agent, mold release agent, etc. to improve impact resistance, lubricity, dispersibility, flame retardant and anti-dropping. Performance. Such as: used as a flame retardant synergist for polyethylene-aluminum hydroxide/magnesium halogen-free flame retardant system, impact modifier and lubricant for general-purpose polystyrene.

The production of polyolefin cables not only has a good flame retardant effect, but also improves the gloss, feel, insulation and aging resistance of the cable surface.

Used in high-grade shoe materials, it can make plastic soles have high wear resistance and scratch resistance.

Second, it is applied to thermoplastics with high filling and halogen-free flame retardant and high filling and strengthening system.

2. GF (glass fiber) reinforced flame retardant PA66 process; low smoke Mg(OH)2 flame retardant PA6 process; HIPS (high punch polystyrene) flame retardant modification process:

3. High-filled flame-retardant PVC modification process; and flame retardant process of other resins (PE\PP\PVC\PU\PF\AF\PET\PBT):

Third, high filling reinforced plastic modification process:

Plastic filling modification refers to adding a certain amount of inorganic or organic filler during the plastic molding process, in order to reduce the cost of the product, or to improve certain properties of the obtained plastic product, or to give some plastic filling Kind of function.
