1. Release agent
Function: By utilizing its non-stick properties with rubber and plastic, methyl silicone oil can effectively prevent the material from sticking to the mold and improve the demolding efficiency.
Application scenarios: Widely used in processes such as polyurethane microporous elastomers, rubber products (such as brake pads), and plastic molding (such as EVA shoe materials), especially suitable for high temperature or complex mold structures.
Advantages: Compared with traditional release agents, its high temperature resistance (up to 200°C) and stability can reduce mold residues and extend mold life.
2. Lubricants and processing aids
Internal lubrication: Directly added to plastics (such as ABS, polyester) to improve melt fluidity, reduce processing resistance, and reduce equipment wear.
External lubrication: Used as a surface lubricant to treat rubber and plastic products (such as seals) to reduce friction coefficient and improve wear resistance.
3. Surface treatment and post-processing
Gloss enhancement: Methyl silicone oil can be applied on the surface of rubber and plastic products to form a hydrophobic film, improve gloss and weather resistance, and is suitable for automotive accessories, decorative materials, etc.
Antistatic treatment: Surface treatment reduces the electrostatic adsorption of rubber and plastic products and improves the performance of industrial parts (such as conveyor belts).
4. Modification of rubber products
Silicone rubber production: As the basic raw material of silicone rubber (such as VMQ, PMQ), it forms an elastomer through vulcanization process, giving it high and low temperature resistance (-50~200℃) and electrical insulation properties.
Performance optimization: Adjusting the degree of vulcanization can control the mechanical properties of rubber such as hardness and tensile strength, and is suitable for sealing rings, shock absorbing components, etc.
5. Defoamer
Application process: In rubber and plastic processing (such as foaming material production), adding methyl silicone oil emulsion can quickly eliminate foam and ensure uniform product structure.
Summary
Methyl silicone oil is used in the rubber and plastic industry through demoulding, lubrication, surface treatment and other multi-dimensional applications, significantly improving processing efficiency and product performance.
