Product Summary
Liquid silicone foam is a high-performance two-part addition curing RTV2 silicone rubber, foamed via chemical reaction of fluid A and B components. It delivers 2–7 times controllable foaming ratio, uniform pores, low shrinkage and stable elasticity at -65℃ to 200℃. Eco-friendly and easy to process, it suits industrial manufacturing. We also offer mold making silicone, pad printing silicone, electronic potting compound, human body silicone and robot silicone.
Product Overview
Also known as foamed silicone and silicone sponge, liquid silicone foam is an eco-friendly platinum-cured dual-component silicone material. It forms lightweight, ultra-soft foam after chemical foaming and high-temperature vulcanization, with no thickness limitation for finished products. Featuring simple operation and stable performance, it reduces production difficulty and material waste, ideal for mass flexible product manufacturing. As a full-range silicone manufacturer, we provide complete industrial silicone material solutions for global B2B buyers.
Technical Specifications
This industrial-grade silicone foam adopts a standard 1:1 mixing ratio for A and B components. It supports 2–7 times stable volume expansion with ultra-low linear shrinkage and excellent rebound resilience. It maintains lasting soft elasticity under long-term service in -65℃ to 200℃ extreme temperature environments. Non-toxic, non-corrosive and radiation-free, it features superior chemical inertness, electrical insulation and flame retardant properties, fully meeting global industrial safety standards.
Product Features & Competitive Advantages
Different from ordinary foam materials, our RTV silicone foam achieves uniform foaming structure with zero migration and atrophy after curing. It integrates excellent heat resistance, cold resistance, insulation and flame retardancy, adapting to complex working conditions. The eco-friendly formula ensures safe contact use, while strict batch QC guarantees stable and consistent quality. Matching the reliability of our mold making silicone and pad printing silicone, it effectively lowers clients’ defective rates and long-term production costs.
Application Scenarios & Buyer Value
Widely applied in multiple industries, it produces industrial gaskets, sealing strips, foam boards and printing sponge rollers. It also manufactures automotive interior accessories, sofa cushions, silicone insoles, kids pillows and fitness equipment parts. Additionally, it serves as premium filling material for robot silicone crafts. Its simplified processing workflow greatly improves production efficiency and cuts raw material consumption for global manufacturers.
Step-by-Step Operation Guide
1. Fully stir component A and B separately to eliminate material stratification caused by long-term storage. 2. Mix the two components at 1:1 ratio and stir evenly for 2–3 minutes to ensure full blending. 3. Conduct vacuum defoaming and use the mixed glue immediately to avoid premature coagulation.
Certifications & Compliance
The product complies with ISO9001, CE and RoHS international quality and environmental standards. Every batch undergoes strict pre-production testing and pre-shipment inspection to ensure reliable global industrial application.
Customization Options
Customizable foaming ratio, hardness and formula parameters are available to meet personalized production demands for different industrial scenarios.
Packaging & Storage Instructions
Standard packaging: A component 25KG/200KG/250KG drums; B component 25KG/200KG drums. Transported as non-dangerous goods. Store in sealed, cool and dry environments. Avoid sunlight exposure, high-temperature baking and contact with water, sulfur, phosphorus and heavy metal impurities.
FAQ
Q1: What causes curing failure of addition curing liquid silicone foam?
A1: This platinum-cured silicone foam is sensitive to specific impurities. Contact with water, sulfur, tin and heavy metal substances will inhibit curing. Long-term sun exposure and high-temperature baking will also damage structural stability.
Q2: Why choose our foamed silicone over competitors?
A2: We provide stable 2–7 times controllable foaming effect, uniform pores, zero shrinkage migration and full international certifications, with consistent batch quality across our entire silicone product lineup.
