Product Overview
Liquid Foamed Silicone is a high-elasticity platinum addition-curing RTV2 silicone rubber designed for industrial sealing, cushioning and thermal insulation applications. Composed of two pourable A and B liquid components, it forms lightweight, soft and highly elastic foam through controlled chemical foaming and heat vulcanization. It supports flexible product thicknesses and is easy to process, while maintaining stable physical properties over long-term use. Resistant to migration, atrophy and structural fatigue, it is a reliable flexible material for global B2B mass production and custom manufacturing.
Technical Specifications
Our industrial liquid foamed silicone uses a standard 1:1 mixing ratio for A and B components. It delivers adjustable volume expansion from 200% to 700%, with ultra-low linear shrinkage and excellent compression recovery. The cured foam retains stable soft elasticity during continuous high and low temperature cycling. It is chemically inert, non-corrosive and non-toxic, with reliable electrical insulation and good flame resistance, meeting international industrial safety and environmental compliance standards.
Product Features & Competitive Advantages
Compared with traditional PU foam and ordinary sponge materials, our liquid foamed silicone provides finer and more uniform cell structure, as well as stronger structural stability. It is lightweight with a comfortable soft touch and resists permanent deformation and aging shrinkage after thousands of compression cycles. The high-purity eco-friendly formula is safe for industrial assembly and consumer product contact. Strict batch-to-batch quality control ensures consistent performance, helping manufacturers reduce reject rates and long-term production costs.
Step-by-Step Operation Guide
1. Stir component A and component B separately to remove sediment and layer separation caused by long-term storage.
2. Mix the two liquid components at a precise 1:1 ratio and stir uniformly for 2–3 minutes until fully homogeneous.
3. Perform vacuum degassing immediately after mixing and apply the silicone mixture quickly to avoid premature curing and ensure uniform foaming results.
Application Scenarios & Buyer Value
This versatile foamed silicone is widely used to produce industrial sealing gaskets, sealing strips, Silicone Foam boards, foam tubes and sponge rollers for printing and copying equipment. It is also suitable for automotive interior parts, household mattresses, sofa cushions, silicone insoles, maternity back support pads and children protective pillows. In addition, it serves as premium filling material for humanoid robot silicone and simulation art silicone products. The simplified process improves production efficiency and reduces raw material waste for large-scale factories.
Certifications and Compliance
Our liquid foamed silicone 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 application in global industrial fields.

Packaging & Storage Instructions
Standard packaging: A component 25KG/200KG/250KG drums; B component 25KG/200KG drums. Classified as non-dangerous goods for international transportation. Store in fully sealed, cool and dry conditions. Avoid direct sunlight and high-temperature baking, and prevent contact with sulfur, phosphorus, heavy metals and water to avoid 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 inhibit normal curing. Long-term sun exposure and excessive high temperature will also damage foam cell uniformity and structural stability.
Q2: Why choose your liquid foamed silicone for industrial production?
A2: Our silicone foam offers stable and adjustable foaming performance, low shrinkage deformation and wide temperature tolerance. With certified quality and consistent batch output, it supports one-stop sourcing together with Mold Making Silicone and Electronic Potting Compound, helping buyers streamline the supply chain and reduce overall production costs.
