Injection Molding Liquid Silicone Rubber
5.5Mpa Injection Molding Liquid Silicone Rubber For Voltages 10 To
500KV
DESCRIPTION
Injection Molding Liquid Silicone Rubber (LSR) is a type of silicone rubber that is specifically designed for injection molding processes. LSR is a unique material that can be molded into complex shapes and intricate parts with high precision and accuracy. The injection molding process involves injecting LSR into a mold cavity under high pressure, where it takes the shape of the mold and cures into a solid material. LSR has excellent mechanical properties, including high elongation, tear resistance, and compression set resistance, making it ideal for use in applications that require durability, flexibility, and heat resistance. Injection molding LSR is a highly efficient and cost-effective process that offers short cycle times, low waste, and high production rates. The unique properties of LSR make it suitable for a wide range of applications, including medical devices, automotive components, consumer goods, and electronics, among others.

FEATURES
APPLICATIONS
1. Medical Devices: LSR is often used to create medical-grade components such as seals, gaskets, tubing, and implants. Its biocompatibility, high purity, and ability to withstand sterilization make it a reliable choice for medical applications.
2. Automotive Industry: Injection molding LSR is used for producing
parts such as seals, gaskets, and connectors in the automotive
industry. LSR's heat resistance, durability, and ability to retain
its shape make it an ideal material for parts that are subject to
high stress and temperature.
3. Consumer Goods: LSR has a wide range of applications in consumer
goods such as kitchenware, baby products, and personal care items.
Its flexibility, heat resistance, and non-stick properties make it
ideal for molds and parts that require durability and ease of use.
4. Electronics Industry: Injection molding LSR is also used for
producing parts such as keypads, seals, and connectors for the
electronics industry. Its electrical insulating properties and
resistance to heat, UV, and weathering make it an excellent
material for these applications.
FAQ
1. What is the shelf life of Injection Molding Liquid Silicone
Rubber?
The shelf life of Injection Molding Liquid Silicone Rubber can vary
depending on the manufacturer, storage conditions, and the specific
type of LSR. Generally, LSR has a shelf life of 12-18 months when
stored in a sealed container in a cool and dry environment.
2. Can Injection Molding Liquid Silicone Rubber be recycled?
Yes, Injection Molding Liquid Silicone Rubber can be recycled using
specialized processes such as pyrolysis or mechanical recycling.
However, the process can be challenging due to the unique
properties of LSR, and the recycled material may not have the same
quality as the original material.
3. What temperatures can Injection Molding Liquid Silicone Rubber
withstand?
Injection Molding Liquid Silicone Rubber can withstand temperatures
ranging from -50°C to 200°C, depending on the specific type of LSR.
The material's thermal stability and insulation properties make it
suitable for high-temperature applications in various industries.
4. How is Injection Molding Liquid Silicone Rubber different from
thermoplastic elastomers?
Injection Molding Liquid Silicone Rubber is a thermoset material
that cures into a solid form, while thermoplastic elastomers are
thermoplastic materials that can be melted and reformed multiple
times. LSR has better properties such as heat resistance,
compression set resistance, and biocompatibility, making it a
preferred choice for specific applications.
