Q: What is liquid silicone rubber?
A: Liquid silicone rubber is a synthetic material composed of silane monomer and cross-linking agent, which exists in liquid form. It has the characteristics of high elasticity, high temperature resistance, chemical corrosion resistance, etc., and is widely used in manufacturing molds, seals, industrial components, etc.

Q: What are the advantages of liquid silicone rubber?
A: Liquid silicone rubber has excellent softness, high temperature resistance, weather resistance and chemical stability. It is easy to process, highly flexible and capable of manufacturing complex-shaped products.

Q: What are the applications of liquid silicone rubber?
A: It is widely used in mold manufacturing, seals, electronic products, medical equipment, food processing equipment and other fields. It is also used in 3D printing, injection molding, infusion molding and other processes.

Q: What is the curing process of liquid silicone rubber?
A: The curing of liquid silicone rubber is accomplished by adding a catalyst or a cross-linking reaction initiated under specific conditions (such as heating or room temperature curing). This reaction causes it to change from a liquid to a solid state.

Q: How to use liquid silicone rubber?
A: Liquid silicone rubber usually needs to be mixed, stirred and filled into the mold or workpiece, and cured. Before use, follow the instructions and operating guidelines provided by the manufacturer.

Q: How durable is liquid silicone rubber?
A: The durability of liquid silicone rubber usually depends on factors such as the specific formula, curing method, and environment. Generally, it has better durability and stability.

Q: What should I pay attention to when cleaning and maintaining liquid silicone rubber?
A: Products made with liquid silicone rubber are generally easy to clean and can be cleaned with mild detergent and water. Keep it away from direct sunlight and extreme temperatures to extend its lifespan.
