2026-08-27
Product Summary
Our liquid silicone foam is a professional two-part addition curing RTV2 silicone rubber, formed by chemical foaming of fluid A and B components. It features 2–7 times high foaming ratio, uniform foam structure, low shrinkage and wide temperature resistance. Eco-friendly and easy to process, it serves industrial sealing and soft product manufacturing. We also supply mold making silicone, pad printing silicone, electronic potting compound, human body silicone and robot silicone.
Product Overview
Liquid silicone foam, also called foamed silicone, silicone foam and silicone sponge, is an eco-friendly dual-component platinum-cured silicone material. It adopts chemical foaming and high-temperature vulcanization molding, with no limitation on finished product thickness. Featuring lightweight texture, soft hand feel and simple operation, it is a versatile industrial material. As a full-line silicone manufacturer, we provide one-stop industrial silicone solutions covering multiple core product lines for global B2B buyers.
Technical Specifications
This industrial-grade foamed silicone adopts standard 1:1 mixing ratio for A/B components. It delivers a controllable foaming expansion of 2 to 7 times volume with ultra-low linear shrinkage and stable rebound performance. The continuous service temperature ranges from -65℃ to 200℃, maintaining stable soft elasticity. It features excellent chemical inertness, insulation, flame retardancy and zero radiation, fully complying with global industrial safety standards.
Product Features & Competitive Advantages
Different from ordinary foam materials, our liquid silicone foam owns superior stability and usability. It achieves uniform foaming pores without migration or atrophy after curing. The non-toxic, non-corrosive formula ensures safe application for household, automotive and body-contact products. With integrated heat resistance, cold resistance and electrical insulation, it adapts to harsh working environments. Stable batch quality reduces defective rates and cuts long-term production costs for manufacturers.
Application Scenarios & Buyer Benefits
It is widely used for industrial sealing accessories such as gaskets, sealing strips, foam boards and printing sponge rollers. It also produces silicone insoles, sofa cushions, automotive headrests, children pillows and fitness device parts. Additionally, it acts as high-quality filling material for robot silicone crafts. Its simple processing flow improves production efficiency and reduces raw material waste for global clients.
Step-by-Step Usage Instructions
1. Fully stir component A and component B separately to eliminate material stratification caused by long-term storage. 2. Mix A and B at a standard 1:1 ratio and stir evenly for 2–3 minutes to ensure uniform glue blending. 3. Perform vacuum defoaming and use the mixed liquid immediately to avoid premature coagulation.
Certifications & Compliance
The product strictly complies with ISO9001, CE and RoHS international quality and environmental standards. Every batch undergoes professional pre-production testing and pre-shipment inspection to guarantee stable and reliable quality.
Customization Options
Customized foaming ratio, hardness and formula adjustments are available to meet personalized industrial application requirements across different industries and production processes.
Packaging & Storage Notes
Standard packaging: A component 25KG, 200KG, 250KG drums; B component 25KG, 200KG drums. It is transported as non-dangerous goods. Store in sealed, cool and dry conditions. Avoid direct sunlight, high-temperature baking and contact with water, sulfur, phosphorus, tin and heavy metal substances.
FAQ
Q1: What causes curing failure of addition curing liquid silicone foam?
A1: This silicone foam is highly sensitive to specific impurities. Contact with water, sulfur, phosphorus, tin and heavy metal compounds will inhibit curing. Long-term sun exposure and high-temperature baking will damage structural stability.
Q2: What is your core advantage over other suppliers?
A2: We provide controllable 2–7 times stable foaming ratio, zero shrinkage and migration, uniform foam pores and full international certifications, with consistent batch quality matching our mold making silicone and pad printing silicone products.
