How to use plastic fill modification?

Plastic fill modification refers to the addition of non-metallic minerals, organic materials, metal powders, and other fillers to the pure resin in order to improve the various properties of the plastic resin, in order to achieve the required technical indicators or increase the cost performance.

Definition of filler

ASTM (American Society for Testing and Materials) defines a filler as a relatively inert substance added to plastics to improve strength and properties, or to reduce costs. Therefore, plastic fillers often choose non-metallic minerals.

As the name implies, non-metallic mineral fillers for plastics are generally considered to be naturally occurring in the field of non-metallic mineral materials that have been artificially mined, processed and characterized by the above defined properties and added to plastics, and are usually made into powders.

Basic properties of the filler

       Ø Maintain chemical and physical stability during plastic processing and use;

Ø Improve certain properties of the resin: increase rigidity, improve heat resistance, and improve electrical insulation;

Ø Improve weather resistance and increase dimensional stability;

Ø Coloring power, thermal conductivity, electrical conductivity, flame retardancy;

Ø Low price.

So it is widely used in plastic recycling machine area. For the good function, and good sales.

STPLAS machinery not only sale plastic recycling granulating machine for fill modification, but also sale Plastic Compounding Machine, mixing machine, plastic crushing washing drying system.
