Product Overview
liquid silicone foam is an advanced addition-curing RTV2 silicone rubber designed for industrial cushioning, sealing and insulation usage. Consisting of two free-flowing A and B liquid components, it forms ultra-light, soft and highly resilient foam after precise chemical foaming and heat vulcanization. This material supports unlimited product thickness, requires simple processing, and maintains stable physical performance for long-term use. It never suffers from material migration, atrophy or structural fatigue, making it a reliable flexible material for global B2B mass production and customized manufacturing. Technical Specifications
This industrial-grade Foamed Silicone adopts a standard 1:1 mixing ratio for A and B components. It delivers controllable 200% to 700% volume expansion with extremely low linear shrinkage and outstanding compression recovery. The finished foam retains stable soft elasticity under continuous high and low temperature cycling. Featuring non-corrosive, non-radioactive and inert chemical properties, it provides superior electrical insulation and flame retardant performance, fully meeting international industrial safety and environmental compliance standards.
Product Features & Competitive Advantages
Compared with conventional foam and sponge materials, our platinum-cured liquid Silicone Foam provides more uniform foam pores and exceptional structural stability. It features lightweight texture and premium soft touch, resisting permanent deformation and aging shrinkage after thousands of compression cycles. Adopting high-purity eco-friendly formula, it is safe for industrial assembly and daily consumer product contact. Strict batch-to-batch quality inspection ensures consistent stable quality, greatly reducing defective rates and long-term operational costs for manufacturers worldwide.
Step-by-Step Operation Guide
1. Thoroughly stir component A and component B individually to eliminate sedimentation and layer separation caused by long-term storage.
2. Mix the two liquid components at a precise 1:1 ratio and stir uniformly for 2 to 3 minutes to achieve full homogenization.
3. Complete vacuum degassing immediately after mixing and apply the silicone mixture promptly to avoid premature curing and guarantee consistent foaming results.
Application Scenarios & Buyer Value
This multi-functional foamed silicone is widely utilized to produce industrial sealing gaskets, sealing strips, foam sheets, silicone foam tubes and printing sponge rollers. It is also extensively used for automotive interior parts, household mattresses, sofa cushions, silicone insoles, maternity back support pads and children protective pillows. Moreover, it serves as high-quality filling material for robot silicone and artistic silicone products. Simplified processing procedures effectively boost production efficiency and minimize raw material waste for large-scale factories.
Certifications and Compliance
This liquid silicone foam complies with ISO9001 quality management system, CE safety standards and RoHS environmental regulations. Every production batch undergoes rigorous performance testing and pre-shipment quality control to ensure stable, safe and reliable global industrial application.

Packaging & Storage Instructions
Standard packaging: A component 25KG/200KG/250KG drums; B component 25KG/200KG drums. Classified as non-dangerous goods for global transportation. Store in fully sealed, cool and dry conditions. Keep away from direct sunlight, high-temperature baking, and avoid contact with sulfur, phosphorus, heavy metals and water to prevent curing inhibition.
FAQ
Q1: What causes uneven foaming or curing failure?
A1: Platinum addition-cured silicone is highly sensitive to external contaminants. Contact with water, sulfur, tin and heavy metals will stop normal curing. Long-term sun exposure and excessive high temperature will also destroy foam uniformity and structural stability.
Q2: Why choose our liquid silicone foam over other suppliers?
A2: Our Foam Silicone features adjustable stable foaming, zero shrinkage deformation and wide temperature adaptability. With certified quality and stable batch consistency, it supports one-stop sourcing with our Mold Making Silicone and Electronic Potting Compound, helping buyers simplify supply chains and reduce overall production costs.
