Product Description
liquid silicone foam is a premium industrial two-part addition curing RTV2 silicone rubber, manufactured through controllable chemical foaming of fluid A and B components. It delivers a flexible 2–7 times adjustable foaming ratio, ultra-uniform internal pore structure, ultra-low shrinkage rate and stable resilient elasticity across -65℃ to 200℃ working temperatures. As a non-toxic, eco-friendly and easy-to-process flexible material, it fits large-scale industrial sealing, cushioning and filling production. We also supply professional Mold Making Silicone, Pad Printing Silicone, Electronic Potting Compound, Human Body Silicone and robot silicone for full industrial silicone solutions.
Product Overview
Also named Foamed Silicone and Silicone Sponge, liquid Silicone Foam is a high-grade platinum-cured dual-component silicone material designed for modern flexible manufacturing. After precise chemical foaming and high-temperature vulcanization, it forms ultra-light and super-soft foam without finished product thickness limitations. Featuring intuitive operation, stable physical performance and low material loss rate, it effectively reduces manufacturing difficulty and production costs, perfectly suitable for mass production of various soft silicone products. As a full-range silicone material supplier, we provide systematic customized silicone solutions for global B2B industrial buyers.
Technical Specifications
This industrial-grade foamed silicone adopts a standard 1:1 weight mixing ratio for A and B components. It supports stable and controllable 2–7 times volume expansion with minimal linear shrinkage and outstanding rebound resilience. The cured foam maintains consistent soft elasticity during long-term service under extreme low and high temperature environments from -65℃ to 200℃. Completely non-toxic, non-corrosive and radiation-free, it features excellent chemical inertness, reliable electrical insulation and superior flame retardancy, fully complying with global industrial safety and environmental standards.
Product Features & Competitive Advantages
Different from ordinary EVA, PU and common sponge materials, our RTV2 liquid silicone foam achieves highly uniform foaming structure with zero shrinkage, zero migration and zero atrophy after long-term compression and aging. It integrates excellent heat resistance, cold resistance, insulation and flame retardant properties, adapting to complex outdoor, mechanical and high-low temperature working conditions. The eco-friendly platinum-cured formula ensures safe human contact application. Supported by strict batch-to-batch quality control, its stable quality is consistent with our mature mold making silicone and pad printing silicone series, helping global manufacturers greatly reduce defective rates and long-term operational costs.
Application Scenarios & Buyer Value
Widely deployed across multiple industrial fields, this silicone foam is used to produce industrial sealing gaskets, anti-collision strips, foam boards and printer sponge rollers. It is also widely applied in automotive interior soft accessories, household sofa cushions, silicone insoles, children’s protective pillows and fitness equipment soft parts. In addition, it serves as high-quality lightweight filling material for humanoid robot silicone crafts and artistic silicone models. Its simplified and mature processing workflow significantly improves production efficiency and reduces raw material waste for global processing factories.
Step-by-Step Operation Guide
1. Fully stir component A and component B separately before use to eliminate material stratification and precipitation caused by long-term storage.
2. Mix the two liquid components strictly at a 1:1 ratio and stir evenly for 2–3 minutes to achieve complete homogeneous blending.
3. Perform vacuum defoaming treatment on the mixed silicone and use it immediately to prevent premature coagulation affecting foaming quality.
Certifications & Compliance
The liquid silicone foam fully complies with ISO9001 quality management system, CE safety certification and RoHS environmental protection standards. Each production batch undergoes rigorous pre-production formula testing and pre-shipment full inspection to guarantee stable and reliable performance for global industrial export applications.
Customization Options
We support personalized customization of foaming ratio, foam density, hardness, color and formula parameters. Custom-tailored solutions are available to meet unique production demands for automotive, electronics, daily consumer goods and intelligent equipment industries.
Packaging & Storage Instructions
Standard packaging: A component 25KG/200KG/250KG drums; B component 25KG/200KG drums. The product is transported as non-dangerous goods. Store materials in sealed, cool and dry indoor environments. Strictly avoid direct sunlight exposure, high-temperature baking, and contact with water, sulfur, phosphorus and heavy metal impurities to prevent curing failure.
FAQ
Q1: What factors lead to curing failure of addition curing liquid silicone foam?
A1: Platinum-cured RTV2 silicone foam is highly impurity-sensitive. Contact with water, sulfur, tin substances and heavy metal contaminants will suppress the curing reaction. Long-term sunlight exposure and high-temperature heating will also damage foam structural stability and cause incomplete foaming.
Q2: What are your core advantages compared with other foamed silicone suppliers?
A2: We provide stably controllable 2–7 times foaming effect, ultra-uniform pore structure, zero shrinkage and no material migration. With complete international certifications and stable batch consistency, our foamed silicone matches the high quality of our full silicone product lineup, bringing higher yield rate and cost-saving benefits for buyers.
