Product Summary
Product Overview
Liquid Silicone Foam , also named Foamed Silicone rubber, is typical two-component heating vulcanized silicone material. Made of fluid A and B raw materials, it turns into soft and lightweight finished products through chemical foaming reaction. Free from thickness limitation, the material delivers comfortable hand feeling and easy operation process. As eco-friendly raw material, it can be well matched with robot silicone and Pad Printing Silicone, serving various sealing, buffering and filling manufacturing demands across multiple fields.
Product Features & Advantages
It reaches 2 to 7 times volume expansion after foaming with stable molding effect. Uniform internal structure brings low linear shrinkage and superb rebound performance, without shrinkage or deformation in long usage. The lightweight property lifts product comfort while maintaining stable toughness. Featured non-toxic, non-corrosive and non-radioactive traits, it holds fine chemical inertness. It keeps soft elasticity steadily within -65℃ to 200℃, and possesses reliable heat resistance, cold resistance, electrical insulation and flame retardant capacity.

Application Scenarios
It is widely applied to produce sealing rings, gaskets, foam boards and sponge tubes for printing rollers. It also makes flexible daily goods like silicone insoles, sofa cushions, car interior accessories, maternity back pads and kids pillows. Besides, it acts as ideal filling material for simulation products made from human body silicone and simulation robot models.
Buyer Core Value
Simple processing flow cuts labor cost and raises production efficiency. Adjustable foaming ratio satisfies diversified production needs and reduces raw material consumption. Stable physical performance lowers defective rate and extends product service life. Good compatibility with multiple core silicone products realizes one-stop purchasing and boosts overall product competitiveness.
Certifications and Compliance
All products conform to RoHS and SGS environmental standards. Supported by ISO9001 quality management system and CE certification, all finished goods meet international export criteria, safe for industrial production and daily contact use.
Customization Options
We provide personalized customization on foaming density, hardness and size specification. Formula adjustment is available to enhance flame retardancy and insulation performance, fitting diverse production demands matched with various silicone series products.
Production Process
We carry out strict raw material screening before production. Precise proportioning and foaming test ensure stable material performance. Semi-finished products will be inspected roundly, and final goods pass comprehensive check before delivery. Pre-production samples can be offered to confirm quality consistency.
Notes
Avoid direct sunlight exposure and high temperature baking. Prevent contact with sulfur, nitrogen, phosphorus, heavy metal substances and moisture, so as not to affect normal curing and inherent performance.
