What is the silicone for waste discharge membranes?

Waste discharge membrane-specific silicone is a special silicone material used in industrial production processes such as waste discharge, die-cutting waste discharge, and surface protection. It is usually made of PET (polyethylene terephthalate) as the base material, combined with a silicone coating, and has the characteristics of high temperature resistance, water resistance, high strength, good adhesion, and environmental recyclability.

Core Definition and Composition: Waste Discharge Membrane-Specific Silicone is a composite material combining the properties of silicone with a PET substrate. It is primarily used for waste discharge, die-cutting waste removal, and surface protection in industrial production. Its typical structure is as follows:

Substrate Layer: PET (Polyethylene Terephthalate) film, providing mechanical strength and stability.

Coating: Silicone coating, imparting properties such as high temperature resistance, water resistance, and high adhesion.

Core Features and Advantages

High Temperature Resistance: The silicone coating can withstand short-term temperatures of 220°C and long-term temperatures of 150°C, making it suitable for high-temperature die-cutting, electronic component fixing, and other applications, ensuring the material does not deform or break under high temperatures.

Water and Moisture Resistance: The water-repellent properties of silicone allow the material to maintain stable adhesion in humid environments, preventing performance degradation due to moisture penetration. Suitable for industries with high moisture resistance requirements, such as electronics and construction.

High Strength and Tear Resistance: The PET substrate provides high tensile strength, and the silicone coating enhances tear resistance, ensuring the material is not easily broken during production. Suitable for applications requiring high tensile strength.

Good Adhesion: The silicone coating effectively bonds to various materials (such as metal, plastic, and glass) and leaves no residue upon peeling. Suitable for applications requiring temporary adhesion, such as electronic component fixing and product transport protection.

Environmental Protection and Recyclability: Using a PET substrate and silicone coating reduces energy consumption and waste emissions during production. The material is recyclable, aligning with green manufacturing trends.

Application Scenarios
Manufacturing: Equipment Isolation and Protection: Used for surface protection of machinery and equipment to prevent scratches or contamination. Die-cutting Waste Removal: Serves as a support structure in the die-cutting process, assisting in waste removal and improving production efficiency.

Electronics Industry: Electronic Component Fixing: Used to fix precision components such as circuit boards and chips, ensuring stability during high-temperature welding or assembly processes.

Screen Protection: Serves as a process protection film for mobile phone lenses, polarizers, and LCD optical lenses, preventing scratches or contamination.

Construction Industry: Construction Site Marking and Warning: Used for affixing safety signs or warning labels; highly weather-resistant and suitable for long-term use.

Logistics Industry: Cargo Fixing and Transportation Protection: Used for wrapping and securing goods, improving transportation safety and reducing damage rates.
