High-Stability Liquid Silicone Foam for Global Industrial Sea

Product Overview

Liquid Silicone Foam is a platinum-cured, two-component addition curing silicone rubber designed for chemical foaming. When Components A and B are combined, this liquid foaming silicone rubber expands into a soft, lightweight, and environmentally friendly material with no restriction on finished part thickness. HONG YE SILICONE, a trusted global supplier of RTV-2 silicone rubber and liquid silicone products, manufactures this foamed silicone under strict ISO9001 quality controls for buyers in over 138 countries.

Product Features and Advantages

1. Exceptional Expansion — Up to 7× volume increase means less raw material per part, directly lowering production costs.
2. Consistent Foam Quality — Uniform cell distribution, stable foaming, low linear shrinkage, and reliable rebound performance batch after batch.
3. Lightweight Comfort — Soft, elastic hand-feel without migration, compression set, or shrinkage over service life.
4. Safe & Inert — Non-toxic, non-corrosive, non-radioactive, and chemically stable — suitable for human body silicone and skin-contact applications.
5. Extreme Temperature Resistance — Retains flexibility and sealing performance from -65°C to 200°C, with inherent heat, cold, electrical insulation, and flame-retardant properties.
6. Process-Friendly — Simple 1:1 ratio, room-temperature or heat-cured, works with manual pouring or automated dispensing equipment.

How to Use — Step by Step

1. Pre-mix Component A and Component B individually to reverse any settling during storage.
2. Combine A and B at 1:1 weight ratio and stir continuously for 2–3 minutes to a uniform consistency.
3. Degas the mixed material under vacuum, then dispense immediately to prevent premature gelation.
4. Cast or inject into the mold; allow foaming and full cure at ambient or elevated temperature.

Application Scenarios

This versatile silicone foam supports a wide range of industries:

• Seals & Gaskets: O-rings, sealing pads, foam strips, foam boards, silicone foam tubing, copier and printer roller sponge sleeves.
• Comfort Products: Silicone insoles, sofa and mattress padding, automotive headrests, gear knob covers, seat cushions.
• Apparel & Wellness: Bra padding, shoulder pads, senior fitness equipment (joint massagers, exercise balls), maternity back supports, infant pillows.
• Specialty Filling: Internal filler for silicone robots, lifecasting mannequins, and prosthetic devices.
• Electronics: Lightweight filler and damper compatible with electronic potting compound assemblies.

Why Buyers Choose It: High expansion cuts material cost; uniform cells improve part consistency; wide temperature range extends product lifespan and reduces warranty claims.
