F664 Strengthens Foam Silicone Rubber Supply for Global Sealing

Product Overview

Foam Silicone Rubber is a two-component addition-curing liquid silicone that chemically expands once the A and B parts are mixed. It cures into a soft, lightweight, and environmentally friendly foam with no thickness restriction and straightforward processing. HONG YE SILICONE, a trusted manufacturer of RTV-2 silicone rubber and liquid silicone, supplies this Foamed Silicone with consistent batch quality to customers in more than 138 countries.

Product Features and Advantages

1. Cost-Saving Expansion — Up to 7× volume increase means less silicone per part, directly lowering your material cost.
2. Stable, Uniform Foaming — Consistent cell structure with low linear shrinkage and reliable rebound for repeatable part quality.
3. Lightweight Softness — Premium elastic feel with no migration, collapse, or shrinkage over time.
4. Eco-Friendly and Safe — Non-toxic, non-corrosive, non-radioactive, and chemically inert; suitable for body silicone and contact applications.
5. Extreme Temperature Performance — Maintains soft elasticity from -65°C to 200°C, with strong heat, cold, electrical insulation, and flame resistance.
6. Process Simplicity — 1:1 mixing, no thickness limits, and compatibility with both manual and automated production.

How to Use — Step by Step

1. Stir each component separately before use to ensure even distribution of settled materials.
2. Combine A and B at a 1:1 weight ratio and mix for 2–3 minutes until fully uniform.
3. Degas the mixture under vacuum and dispense immediately to prevent premature gelling.
4. Pour or inject into the mold and allow foaming and curing at room temperature or with gentle heating.

Application Scenarios

• Sealing & Insulation: Gaskets, sealing strips, foam sheets, Silicone Foam tubes, and printer roller sponges.
• Automotive & Home: Headrests, gear shift covers, seat cushions, sofa and mattress padding.
• Health & Wellness: Bra inserts, shoulder pads, maternity back supports, infant pillows, and senior fitness equipment.
• Model & Filling: Core filler for silicone robots, lifecasting figures, and prototype parts — complementing Mold Making Silicone and Prototype silicone workflows.
• Electronics: Lightweight damping and filling used alongside Electronic Potting Compound applications.

Value to Buyers: Reduced material spend, more consistent output, and durable sealing or cushioning that reinforces your product's quality and reputation.
