  plastic recycling machinery for plastic composition has a great demand. The basic ingredient is composed of plastic resin, known as matrix material. According to the actual needs of the plastic material in general also contain many other ingredients, known as additives, these additives to improve performance or process performance materials. Thermoplastics are sometimes used in the form of pure resin, thermosetting plastic is completely added additives to form. Plastic material with additives of many varieties, including fillers, reinforcing agents, plasticizers, lubricants, antioxidants, heat stabilizers, light stabilizers, flame retardants, colorants, antistatic agents, curing agents, foaming agents and certain other additives. The basic requirements for effective aid is functionally stable under the conditions of use of plastics processing, and resin bonded firmly, without dialysis and blooming, non-toxic, odorless, affordable. Dialysis means an additive to other plastics materials in contact with the migration phenomenon. Dialysis occurs because the additives have some solubility in the resin matrix material, may also have some solubility in the materials in contact. Blooming refers to a plastics additives to the product surface migration phenomenon, generally refers mainly plasticizers and lubricants. When the additive is completely dissolved at the processing temperature in the resin, but only partially dissolved at room temperature, the molded article will blooming phenomenon when using or storing at room temperature. Different plastic components, different degree of processing plastic granulator on it.
Plastic filler is to improve certain physical properties, such as thermal conductivity, swelling, heat resistance, hardness, shrinkage, dimensional stability, etc., may also be mixed with or in order to improve the mechanical properties of the material to improve certain, sometimes , the filler is mainly used to reduce the material cost.
