Product Overview
Liquid silicone foam is a premium industrial-grade addition curing silicone material composed of two flowable A and B liquid components. It forms ultra-light, super-soft and highly resilient foam through precise chemical foaming and high-temperature vulcanization. The material supports unlimited finished product thickness, features intuitive processing steps and exceptional long-term structural stability without migration, atrophy or deformation after repeated use. As a multi-functional industrial foam material, it complements our full silicone product series to support one-stop customized manufacturing services for global B2B industrial buyers.
Technical Specifications
This industrial RTV2 foamed silicone adopts a standard 1:1 weight mixing ratio for A and B components. It achieves stable adjustable foaming volume from 200% to 700%, featuring ultra-low linear shrinkage rate and outstanding rebound performance. The cured foam maintains consistent soft and elastic properties under long-term extreme high and low temperature environments. With non-toxic, non-corrosive and non-radioactive characteristics, it provides excellent chemical inertness, superior electrical insulation and reliable flame retardancy, fully meeting international industrial safety and environmental standards.
Product Features & Competitive Advantages
Different from traditional PU foam and ordinary sponge materials, our liquid foamed silicone achieves highly uniform foaming pores and excellent structural stability. It features lightweight texture and skin-friendly soft touch, resisting permanent shrinkage and deformation after long-term compression and aging tests. Adopting high-purity platinum-cured formula, it guarantees full environmental safety for industrial assembly and daily product contact. With strict batch quality control, its stable performance is consistent with our high-standard mold making silicone and pad printing silicone, helping global manufacturers lower defective rates and optimize overall production costs.
Operation Steps
1. Fully stir component A and component B separately before use to eliminate material stratification and precipitation caused by long-term sealed storage. 2. Mix the two liquid components strictly at a 1:1 ratio and stir thoroughly for 2–3 minutes to achieve complete homogeneous blending. 3. Perform vacuum defoaming immediately after mixing and use the compound silicone quickly to avoid premature coagulation and ensure uniform foaming effect.
Application Scenarios & Buyer Value
This multi-purpose silicone foam is widely manufactured into industrial sealing gaskets, sealing strips, foam boards and printer sponge rollers. It is also widely applied for automotive interior parts, household sofa cushions, silicone insoles, fitness equipment accessories and children soft protective products. Additionally, it serves as high-quality lightweight filling material for robot silicone crafts and flexible silicone models. Its simplified processing workflow effectively improves production efficiency, shortens molding cycles and reduces raw material waste for large-scale industrial factories.
Certifications and Compliance
This liquid silicone foam complies strictly with ISO9001 quality management system, CE safety certification and RoHS environmental protection regulations. Every production batch undergoes comprehensive performance testing and hazardous substance inspection to ensure stable, safe and reliable performance for global industrial and consumer product applications.

Packaging & Storage Instructions
Standard packaging: Component A in 25KG/200KG/250KG drums; Component B in 20KG/25KG/200KG drums. Transported as non-dangerous goods for global shipping. Store in fully sealed, cool and dry indoor conditions. Avoid direct sunlight exposure and high-temperature baking, and prevent contact with sulfur, phosphorus, tin, heavy metal substances and water to avoid curing failure.
FAQ
Q1: What causes abnormal curing and foaming failure of liquid silicone foam?
A1: Platinum addition-curing silicone is extremely sensitive to impurity contamination. Contact with water, sulfur, tin, heavy metals and harmful chemical substances will inhibit the curing reaction. Long-term sunlight exposure and continuous high-temperature baking will also damage foam internal structure and lead to foaming failure.
Q2: What core production benefits can this foamed silicone bring to industrial buyers?
A2: It provides stable adjustable foaming performance, ultra-uniform pore structure and zero shrinkage deformation. Featuring wide temperature resistance, excellent insulation and flame retardant properties, it greatly reduces product defects and production costs. It can be perfectly matched with electronic potting compound, mold making silicone and other silicone materials to realize efficient one-stop raw material procurement.
