What is Silicone Rubber?
Silicone rubber is a high-performance elastomer derived from silicon, oxygen, carbon, and hydrogen. Its unique molecular structure features a siloxane backbone (Si-O bonds) with organic side groups such as methyl, vinyl, or phenyl, 赋予 it a rare combination of durability, flexibility, and chemical stability. This hybrid organic-inorganic composition sets it apart from traditional rubbers, enabling exceptional performance across extreme conditions.
Key Features
Temperature Resistance: Withstand -60°C to 250°C, maintaining elasticity and integrity in both freezing and scorching environments.
Chemical Stability: Resistant to oils, solvents, ozone, UV radiation, and weathering, making it ideal for harsh industrial settings.
Electrical Insulation: Excellent dielectric properties ensure safe use in high-voltage applications.
Biocompatibility: Non-toxic and inert, approved by regulatory bodies like the FDA for medical and food contact uses.
Mechanical Flexibility: High elongation and low compression set provide long-lasting sealing and cushioning capabilities.
Types of Silicone Rubber
High-Temperature Vulcanized (HTV):
Processed at elevated temperatures using peroxide or platinum catalysts.
Used in automotive gaskets, electrical insulation, and medical devices due to its dimensional stability.
Room Temperature Vulcanized (RTV):
Cures without heat, available in one-part (RTV-1) or two-part (RTV-2) systems.
Ideal for adhesives, sealants, and mold-making in construction and electronics.
Liquid Silicone Rubber (LSR):
Low-viscosity, injectable material with precise molding capabilities.
Popular in medical devices, automotive sensors, and consumer goods for its transparency and high purity.
Applications
Medical: Implants, catheters, and prosthetics leverage its biocompatibility.
Automotive: Gaskets, seals, and engine components endure heat and chemicals.
Electronics: Insulation for wires, connectors, and LED encapsulation.
Food & Beverage: FDA-approved tubing, baking mats, and bottle nipples.
Aerospace: Seals and coatings for extreme temperature and pressure resistance.
