Advantages and application range of liquid silicone rubber (LSR)

1. Advantages of LSR liquid silicone
Excellent physical properties
High elasticity and resilience: LSR has excellent elasticity and can quickly return to its original shape after being stressed, which is suitable for application scenarios that require frequent deformation.
High and low temperature resistance: It can maintain stable performance in the extreme temperature range of -60℃ to 250℃, suitable for high temperature disinfection and low temperature environment.
Aging resistance: It has excellent UV resistance, oxidation resistance and weather resistance, and has a long service life.
Biocompatibility and safety
Non-toxic and odorless: It meets food grade and medical grade standards and is suitable for products that come into direct contact with the human body.
Low allergenicity: It has low irritation to the skin and mucous membranes and is widely used in medical and maternal and child products.
Chemical stability
Corrosion resistance: It has excellent tolerance to chemicals such as acids, alkalis, and salts, and is suitable for the chemical and medical fields.
Waterproof and moisture-proof: The surface is highly hydrophobic and can effectively prevent moisture penetration.
Processing performance
Good fluidity: The liquid form is easy to form through injection molding, extrusion and other processes, and is suitable for the design of complex structures.
Fast curing: It can be vulcanized quickly under the action of catalyst to improve production efficiency.
High transparency: It can produce transparent or translucent products to meet the appearance requirements.
Environmental protection
Recyclable: Some LSR materials can be recycled and reprocessed to reduce environmental impact.
Low emission: The emission of volatile organic compounds (VOC) during the production process is low, which complies with environmental regulations.
