The polymer (PP, PA, BAS, etc.) is used as the base resin, and the inorganic filler (calcium carbonate, talcum powder, etc.) is added and is mixed with the resin uniformly, to reach the aim of reducing material cost, increasing product rigidity, improving the heat resistance temperature of the product, and reducing thermal shrinkage, etc.
The plastic particles, additives and powders are fed into the filler modification extruder in the form of multiple feeding, high precision of proportioning, avoiding material layering and bridging. The simple formulation can also adopt premix process by high speed mixer, and then fed into twin screw extruder.
The assembly structure of barrels and screw elements can be adjusted according to the requirements of plastic compounding and dispersion, side feeding, exhaust and vacuum, etc, to meet their different process requirements.
