What is the special silicone for waste discharge membrane

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

Core Definition and Composition
Silicone for waste disposal film is a composite material that combines the properties of silicone with a PET substrate. It is primarily used for waste disposal, die-cutting waste disposal, and surface protection in industrial production. Its typical structure is:

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 applications such as high-temperature die-cutting and electronic component mounting, ensuring the material remains stable and undamaged under high temperatures.
Water and Moisture Resistance
The silicone's water repellency ensures secure adhesion even in humid environments, preventing performance degradation due to moisture penetration. It is suitable for industries such as electronics and construction that require high moisture resistance.
High Strength and Tear Resistance
The PET substrate provides high tensile strength, while the silicone coating enhances tear resistance, ensuring the material resists breakage during production. It is suitable for applications requiring high tensile forces.
Excellent Adhesion
The silicone coating effectively bonds to a variety of materials (such as metal, plastic, and glass), leaving no adhesive residue when peeled off. It is suitable for temporary applications such as electronic component mounting and product transportation protection.
Environmental Protection and Recyclability
The use of a PET substrate and silicone coating reduces energy consumption and waste emissions during production, and the material is recyclable, aligning with the trend of green manufacturing.
Applications
