Product Summary
Product Overview
Liquid Silicone Foam is a professional addition curing dual-component silicone rubber, commonly known as Foamed Silicone and silicone sponge. Composed of flowable A and B liquid components, it forms lightweight, ultra-soft elastic foam through precise chemical foaming and high-temperature vulcanization. The material supports unlimited product thickness, features simple processing and stable physical performance. It never suffers from migration, atrophy or permanent deformation after long-term repeated use, becoming an ideal eco-friendly flexible material for global mass industrial production.
Technical Specifications
This industrial-grade RTV2 foamed silicone adopts standard 1:1 weight mixing ratio. It realizes stable 2–7 times adjustable volume expansion with ultra-low linear shrinkage rate and excellent compression resilience. The cured foam maintains stable soft elasticity under long-term extreme high and low temperature environments. With non-toxic, non-corrosive and non-radiative features, it owns superior chemical inertness, electrical insulation and flame retardancy, fully complying with international industrial safety and environmental standards.
Product Features & Competitive Advantages
Different from traditional foam materials, our platinum-cured liquid silicone foam delivers uniform foaming pores and excellent structural stability. It is lightweight with delicate skin-friendly hand feel, maintaining perfect elasticity without shrinkage after long-term compression and aging. Adopting imported eco-friendly formula, it ensures safe contact for civilian and industrial products. Strict batch quality control ensures consistent stable quality, same as our high-quality mold making silicone and pad printing silicone, effectively reducing factory defective rate and long-term production costs.
Operation Steps
1. Thoroughly stir component A and component B separately to eliminate material stratification and precipitation caused by long-term sealed storage.
2. Mix A and B components strictly at 1:1 ratio and stir evenly for 2–3 minutes to achieve full homogeneous blending.
3. Complete vacuum defoaming immediately after mixing and use the mixed silicone quickly to avoid premature curing and ensure standard foaming quality.
Application Scenarios & Buyer Value
This multi-functional industrial silicone foam is widely used to produce industrial sealing gaskets, sealing strips, foam boards and printing sponge rollers. It is also extensively applied in automotive interior parts, household sofa cushions, silicone insoles, maternity back pads, children pillows and fitness equipment accessories. In addition, it serves as high-quality lightweight filling material for robot silicone and silicone craft products. Simple and efficient processing greatly improves production efficiency and reduces raw material waste for global manufacturers.
Certifications and Compliance
The liquid silicone foam strictly complies with ISO9001 quality system, CE safety certification and RoHS environmental protection standards. Each production batch undergoes comprehensive professional testing and pre-shipment inspection to ensure stable and reliable global industrial application.
Customization Options
We support personalized customization of foaming ratio, foam density, hardness and formula parameters to meet diverse production needs in automotive, electronic, 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 in sealed, cool and dry indoor environment. Avoid direct sunlight exposure, high-temperature baking, and contact with water, sulfur, phosphorus and heavy metal impurities to prevent curing failure.
FAQ
Q1: Why does the liquid silicone foam fail to cure normally?
A1: Platinum addition-cured silicone is highly sensitive to impurities. Contact with water, sulfur, tin, heavy metals and harmful chemicals will inhibit curing reaction. Long-term sunlight exposure and high-temperature baking will also damage foam internal structure and cause foaming failure.
Q2: What industrial advantages does this foamed silicone have over competitors?
A2: It features adjustable stable foaming performance, uniform pore structure and zero deformation. With ultra-wide temperature resistance and excellent insulation performance, it adapts to complex working conditions. It can be matched with electronic Potting Compound, mold making silicone and other silicone materials to realize one-stop procurement and reduce overall production costs.
