Product Summary (200 characters)
Our liquid silicone foam is a two-part addition curing RTV2 silicone rubber, made of flowable A and B components with chemical foaming technology. It features 2–7 times controllable foaming ratio, uniform pores, low shrinkage and -65℃ to 200℃ temperature resistance. Eco-friendly and easy to process, it supports industrial sealing and cushioning production. 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 a high-performance dual-component platinum-cured silicone material. It forms lightweight, soft foam after chemical foaming and high-temperature vulcanization, with no restriction on finished product thickness. Featuring simple operation, stable performance and environmental safety, it is a cost-effective industrial material for mass production. As a full-line silicone supplier, we provide integrated silicone solutions for global B2B buyers.
Technical Specifications
This industrial foamed silicone adopts 1:1 standard mixing ratio for A/B components. It delivers 2–7 times stable volume expansion with ultra-low linear shrinkage and excellent rebound performance. It maintains permanent soft elasticity at -65℃ to 200℃, with reliable electrical insulation, flame retardancy and chemical inertness. Non-toxic, non-corrosive and radiation-free, it meets global industrial safety production standards.
Core Product Features & Advantages
Different from ordinary foam materials, our RTV silicone foam has stable and uniform foaming structure without migration or atrophy after curing. It owns outstanding heat and cold resistance, adapting to extreme working environments. The eco-friendly formula supports long-term repeated use, effectively reducing product replacement frequency. Strict batch quality control ensures stable performance, helping manufacturers lower defective rate and overall production costs.
Application Scenarios & Buyer Value
It is widely used for industrial sealing parts such as gaskets, sealing strips, foam boards and printing sponge rollers. It also produces automotive interior accessories, sofa cushions, silicone insoles, kids pillows and fitness equipment components. In addition, it serves as premium filling material for robot silicone crafts. Its simple processing flow greatly improves production efficiency and reduces raw material waste.
Step-by-Step Usage Instructions
1. Stir component A and B separately to eliminate material settlement caused by long-term storage. 2. Mix the two components at 1:1 ratio and stir evenly for 2–3 minutes. 3. Conduct vacuum defoaming and use the mixture quickly to avoid premature coagulation.
Certifications & Customization
The product complies with ISO9001, CE and RoHS international standards with full batch inspection. Customized foaming ratio and hardness formulas are available to meet personalized industrial application needs.
Packaging & Storage Guidelines
Standard packaging: A component 25KG/200KG/250KG drums; B component 25KG/200KG drums. Transported as non-dangerous goods. Store in sealed, cool and dry places. Avoid sunlight exposure, high-temperature baking and contact with water, sulfur, phosphorus and heavy metal substances.
FAQ
Q1: Why does addition curing liquid silicone foam fail to cure?
A1: Curing failure is mainly caused by contact with water, sulfur, tin and heavy metal impurities. Long-term sun exposure and high-temperature baking will also damage foam stability.
Q2: What is your core competitive advantage?
A2: We provide controllable 2–7 times stable foaming effect, zero shrinkage and migration, uniform pores and full certifications, with consistent quality same as our mold making silicone and pad printing silicone products.
