Product Summary
Product Overview
Liquid Silicone Foam is a professional-grade addition curing silicone material formulated with dual flowable A/B liquid components. It forms ultra-light, soft and highly elastic foam through controllable chemical foaming and high-temperature vulcanization. The material imposes no thickness restrictions on finished products and features simple operation workflow and excellent long-term stability, without atrophy, migration or structural deformation. As a reliable multi-purpose industrial material, it complements our full silicone product lineup to deliver complete one-stop material support for global B2B manufacturers.
Technical Specifications
This industrial RTV2 foamed silicone adopts a standard 1:1 weight mixing ratio for A and B components. It delivers stable adjustable foaming volume ranging from 200% to 700% with minimal linear shrinkage and superior resilience. The cured foam retains consistent soft elasticity under long-term extreme high and low temperature conditions. Featuring non-toxic, non-corrosive and non-radioactive properties, it possesses excellent chemical inertness, electrical insulation and flame retardant capability, fully compliant with international industrial safety norms.
Product Features & Competitive Advantages
Compared with conventional sponge and foam materials, our liquid foamed silicone achieves highly consistent foaming uniformity and outstanding structural stability. It is lightweight with premium soft tactile performance, resisting permanent deformation and shrinkage after repeated compression and long-term aging. Adopting high-purity platinum-cured formula, it ensures full environmental safety for both industrial and civilian contact scenarios. Supported by strict batch-to-batch quality control, its stable quality matches our premium mold making silicone and pad printing silicone standards, helping global clients reduce defective rates and cut long-term manufacturing costs.
Operation Steps
1. Fully stir component A and component B separately before use to eliminate layering and precipitation caused by long-term storage.
2. Mix the two components strictly at 1:1 ratio and stir thoroughly for 2–3 minutes to achieve uniform blending.
3. Complete vacuum defoaming promptly and apply the mixed silicone immediately to avoid premature coagulation that affects foaming uniformity.
Application Scenarios & Buyer Value
This versatile silicone foam is extensively used to manufacture industrial sealing gaskets, sealing strips, foam boards and printer sponge rollers. It is also ideal for producing automotive interior accessories, household sofa cushions, silicone insoles, fitness equipment parts and safe soft products for children. In addition, it serves as premium lightweight filling material for robot silicone artworks and flexible silicone models. Optimized processing greatly boosts production efficiency, shortens molding cycles and minimizes raw material waste for mass-production factories.
Certifications and Compliance
The liquid silicone foam strictly complies with ISO9001 quality management system, CE safety standards and RoHS environmental protection regulations. Every production batch undergoes rigorous performance testing and hazard inspection to guarantee stable, reliable and safe application across global industrial and consumer product fields.

Packaging & Storage Instructions
Standard packaging: Component A in 25KG/200KG/250KG drums; Component B in 20KG/25KG/200KG drums. Classified as non-dangerous goods for global transportation. Store materials in fully sealed, cool and dry indoor environments. Keep away from direct sunlight, high-temperature baking, and avoid contact with sulfur, phosphorus, tin, heavy metal substances and water to prevent curing failure.
FAQ
Q1: What causes abnormal curing and foaming failure of liquid silicone foam?
A1: Platinum addition-curing silicone is highly impurity-sensitive. Contact with water, sulfur, tin, heavy metals and harmful chemical contaminants will suppress the curing reaction. Prolonged sunlight exposure and continuous high-temperature heating will also damage the internal foam structure and cause performance failure.
Q2: What core production benefits can this foamed silicone bring to industrial buyers?
A2: It delivers stable adjustable foaming effect, ultra-uniform pores and zero shrinkage deformation. With wide temperature adaptability and excellent insulation and flame retardant properties, it effectively reduces production defects and processing costs. It can be perfectly matched with electronic Potting Compound, mold making silicone and other silicone materials to realize efficient one-stop raw material procurement.
