Product Overview
Liquid Foamed Silicone rubber is a high-grade platinum addition-curing RTV2 silicone rubber tailored for industrial sealing, shock absorption and thermal insulation. It comprises two flowable A and B liquid parts. Through regulated chemical foaming and heat vulcanization, it turns into ultra-light, soft and resilient foam. No restriction is placed on finished product thickness, and the whole processing workflow is simple. It keeps stable physical properties throughout long-term use, free of material migration, atrophy or structural fatigue, which makes it a trusted flexible material for global B2B mass production and custom fabrication.
Technical Specifications
This industrial foamed silicone adopts a standard 1:1 mixing ratio for A and B components. It supports adjustable volume expansion from 200% to 700%, featuring ultra-low linear shrinkage and excellent compression recovery. The cured foam maintains stable soft elasticity under repeated high and low temperature cycling. It has chemically inert, non-corrosive and non-toxic properties, offering reliable electrical insulation and good flame retardancy, complying fully with international industrial safety and environmental compliance standards.
Product Features & Competitive Advantages
Different from traditional PU foam and ordinary sponge materials, our platinum-cured liquid foamed silicone forms finer, evenly distributed pores and stronger structural stability. It is lightweight with a smooth soft touch and can withstand thousands of compression cycles without permanent deformation or aging shrinkage. Adopting high-purity eco-friendly formulation, it is safe for industrial assembly and consumer product contact. Strict batch quality testing ensures stable performance, lowering reject rates and long-term manufacturing costs for global manufacturers.
Step-by-Step Operation Guide
1. Stir component A and component B separately to eliminate sediment and layer separation caused by long-term storage.
2. Mix A and B at the precise 1:1 proportion and stir evenly 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 guarantee uniform foaming results.
Application Scenarios & Buyer Value
This versatile foamed silicone is widely used to produce industrial sealing gaskets, sealing strips, Silicone Foam sheets, foam tubes and sponge rollers for printing and copying machines. It is also applied in automotive interior accessories, household mattresses, sofa cushions, silicone insoles, maternity back cushions and children protective pillows. Additionally, it acts as premium filling material for humanoid robot silicone and simulation art silicone products. The simplified processing 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. Each production batch undergoes strict performance testing and pre-shipment QC inspection to guarantee stable, safe and reliable application in global industrial scenarios.

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 environments. Avoid direct sunlight and high-temperature baking. Prevent contact with sulfur, phosphorus, heavy metals and water, or curing inhibition will occur.
FAQ
Q1: What leads to uneven foaming or curing failure?
A1: Platinum addition-cured silicone is highly sensitive to 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 select HONG YE SILICONE liquid foamed silicone for your manufacturing?
A2: Our silicone foam features controllable and stable foaming performance, low shrinkage deformation and broad temperature resistance. With certified quality and consistent batch performance, we support one-stop procurement with our Mold Making Silicone and Electronic Potting Compound, helping buyers streamline supply chains and reduce overall production costs.
