Liquid Silicone Foam | Two-Component Foamed Silicone Rubber

Product Overview

Liquid Silicone Foam is a two-component addition curing silicone rubber that chemically expands when Components A and B are mixed. Also known as foamed silicone or silicone foam, this platinum-cured RTV silicone foam delivers a lightweight, soft, and eco-friendly material with no thickness limitations. As a leading manufacturer of RTV-2 silicone rubber and mold making silicone, HONG YE SILICONE provides consistent foaming performance trusted by buyers across 138+ countries.

Product Features and Advantages

1. High Expansion Ratio — Foams to 2× original volume, up to 7× maximum, significantly reducing material cost per unit volume.
2. Uniform Cell Structure — Consistent foaming with excellent stability, low linear shrinkage, and superior rebound resilience.
3. Lightweight & Soft — Premium elastic hand-feel with no migration or shrinkage over time.
4. Eco-Friendly & Safe — Non-toxic, non-corrosive, non-radioactive, and chemically inert; suitable for sensitive applications including human body silicone components.
5. Wide Temperature Tolerance — Maintains soft elasticity from -65°C to 200°C, with outstanding heat, cold, electrical insulation, and flame-retardant properties.
6. Easy Processing — No thickness limitation; simple 1:1 mix ratio compatible with standard dispensing and pouring equipment.

How to Use — Step by Step

1. Stir Components A and B separately and thoroughly before use to ensure uniform material distribution.
2. Mix A and B at a 1:1 weight ratio and stir for 2–3 minutes until fully homogeneous.
3. Degas the mixture under vacuum and use promptly to avoid pre-curing or condensation affecting production.
4. Pour or dispense into the mold or target area; allow foaming and curing at room temperature or with gentle heating.
