Silicone powder, a plastic lubricant, is a functional additive widely used in the plastics processing industry. Here is a detailed introduction:

I. Basic Information

Definition: Silicone powder is a powdered additive typically made from siloxane polymers and ultrafine inorganic fillers through a special process. It effectively improves the flowability and release properties of plastics during processing, and also imparts certain special properties to plastic products.

Appearance: Generally a white or light yellow powder with a fine texture and no obvious odor.

II. Working Principle

Reducing Surface Friction: The siloxane segments in the silicone powder molecules can form a low-friction lubricating film on the plastic surface. When the plastic flows in processing equipment (such as injection molding machines, extruders, etc.), this lubricating film can greatly reduce the friction between the plastic and the metal surface of the equipment, as well as between the plastic molecules themselves, thereby making the plastic flow smoother, reducing processing energy consumption, and improving production efficiency.

Improved demolding performance: During the molding process of plastic products, silicone powder can form a lubricating interface between the mold and the plastic product, effectively preventing the plastic product from sticking to the mold during demolding, ensuring that the product can be demolded smoothly, reducing the defect rate, and also extending the service life of the mold.
