Industrial RTV2 Addition Foamed Silicone

Liquid silicone foam is a professional two-part addition curing RTV2 silicone rubber, made of flowable A and B components via chemical foaming. It delivers 2–7 times controllable foaming ratio, uniform pores, low shrinkage and stable flexibility at -65℃ to 200℃. Eco-friendly and easy to process, it fits industrial sealing and soft product manufacturing. We supply matched mold making silicone, pad printing silicone, electronic potting compound, human body silicone and robot silicone.

 

Also known as foamed silicone and silicone sponge, liquid silicone foam is a high-performance platinum-cured dual-component silicone material. It is formed by chemical foaming and high-temperature vulcanization, featuring ultra-light texture, soft hand feel and no limitation on finished product thickness. With simple operation, stable physical properties and eco-friendly formula, it avoids material waste and supports continuous mass production, serving as a cost-effective solution for global industrial flexible manufacturing.

This industrial-grade addition curing silicone adopts a standard 1:1 mixing ratio for A and B components. It achieves 2–7 times stable volume expansion with ultra-low linear shrinkage and excellent rebound resilience. It maintains long-term stable soft elasticity in extreme temperatures ranging from -65℃ to 200℃. Non-toxic, non-corrosive and radiation-free, it features superior chemical inertness, electrical insulation and flame retardancy, fully complying with global industrial safety standards.

Different from ordinary foam materials, our RTV silicone foam features evenly distributed foam pores and zero migration or atrophy after curing. It integrates excellent heat resistance, cold resistance, insulation and flame retardant performance, adapting to complex and harsh working conditions. The safe and non-toxic formula supports direct human contact applications. Strict batch quality control ensures consistent stability, keeping the same high quality as our mainstream mold making silicone and pad printing silicone products, effectively reducing clients’ defective rates and production costs.

Widely applied in multiple industries, it manufactures industrial gaskets, sealing strips, foam boards and printing sponge rollers. It also produces automotive interior accessories, sofa cushions, silicone insoles, kids pillows and fitness equipment parts. In addition, it acts as premium filling material for robot silicone crafts. Its simplified processing workflow improves production efficiency, shortens processing cycles and cuts raw material consumption, bringing obvious cost-saving benefits for global B2B manufacturers.

1. Fully stir component A and component B separately to eliminate material stratification caused by long-term storage. 2. Mix the two components at a standard 1:1 ratio and stir evenly for 2–3 minutes to ensure full uniform blending. 3. Conduct vacuum defoaming for the mixed glue and use it immediately to prevent premature coagulation affecting production.

The product strictly complies with ISO9001, CE and RoHS international quality and environmental standards. Every batch undergoes rigorous pre-production testing and pre-shipment full inspection to ensure stable and reliable global industrial application.

Customizable foaming ratio, hardness and formula parameters are available to meet personalized production demands for different industrial scenarios and processing technologies.

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 direct sunlight exposure, high-temperature baking and contact with water, sulfur, phosphorus and heavy metal impurities.

Q1: Why does addition curing liquid silicone foam fail to cure?

A1: This platinum-cured silicone foam is highly sensitive to specific impurities. Contact with water, sulfur, tin and heavy metal substances will inhibit curing reaction. Long-term sunlight exposure and high-temperature baking will also damage foam structural stability.

Q2: What makes your foamed silicone competitive?

A2: We provide stable 2–7 times controllable foaming performance, uniform pores, zero shrinkage migration and complete international certifications, with consistent batch quality across our full silicone product lineup.
