Optimized Liquid Silicone Foam Offers Stable Foaming Performance

Product Overview

Liquid Foam Silicone is an addition-cured, two-component silicone rubber engineered for chemical foaming. When the A and B liquid parts meet, the compound expands into a soft, featherlight, environmentally safe foam with no limit on part thickness. HONG YE SILICONE, a veteran manufacturer of Mold Making Silicone and RTV-2 silicone rubber, brings 23+ years of silicone expertise to every batch of this Foamed Silicone, trusted by buyers across the Americas, Europe, Asia, and Africa.

Product Features and Advantages

1. Cost-Efficient High Expansion — Foams to 2× naturally and up to 7× at maximum, cutting silicone consumption per finished part and improving your cost position.
2. Dependable Foaming Consistency — Even cell distribution and stable expansion deliver uniform parts with minimal shrinkage and strong rebound.
3. Featherlight Softness — Lightweight with premium elastic hand-feel, free of migration or shrinkage during service.
4. Safe and Inert — Non-toxic, non-corrosive, non-radioactive, chemically stable — suitable for Human Body Silicone and skin-contact products.
5. Built for Temperature Extremes — Maintains soft elasticity from -65°C to 200°C with excellent heat, cold, electrical insulation, and flame resistance.
6. Easy to Process — No thickness restriction, simple 1:1 ratio, and compatibility with manual or automated dispensing systems.

How to Use — Step by Step

1. Thoroughly stir each component first so any settled material is evenly redistributed.
2. Mix A and B at a 1:1 weight ratio, stirring for 2–3 minutes until completely uniform.
3. Vacuum-degas the mixture and dispense immediately to avoid thickening that could halt production.
4. Pour or inject into the mold and let the material foam and cure at room temperature or with gentle heating.

Application Scenarios

• Sealing Systems: Gaskets, sealing pads, sealing strips, foam boards, Silicone Foam tubes, and copier/printer roller sponges.
• Automotive Interiors: Headrests, gear lever covers, seat cushions, and cabin padding.
• Daily Comfort: Silicone insoles, sofa cushions, mattresses, and padded home accessories.
• Health and Wellness: Bra inserts, shoulder pads, maternity back supports, infant pillows, and senior fitness equipment.
• Model and Filler Use: Core filling for silicone robots, lifecasting figures, and prototype props — an ideal companion to Prototype silicone and liquid silicone molding.

Value for Buyers: Lower material spend via high expansion, higher output consistency via uniform cells, and lower warranty risk via long-term temperature durability.

Certifications and Compliance

ISO9001-certified production with UL and CE certifications supports global compliance. Our Addition Curing Silicone grades meet widely recognized safety and environmental requirements, easing qualification and customs clearance in major export markets.

Customization Options

We offer adjustable hardness and expansion ratio, custom colors, low-viscosity grades for automated lines, enhanced flame-retardant versions, and food-contact or medical-grade formulations to match your exact application.

Production Process

Raw material incoming inspection → precision batching of A/B → vacuum compounding and degassing → laboratory testing (viscosity, expansion, hardness) → sealed drum packaging → final inspection before shipment. Supported by 48 production lines and a mature quality system.

FAQ

Q: Can I get a sample before ordering? A: Yes. We always arrange pre-production samples before mass production and complete final inspection before shipment, so you can validate quality first.

Q: What is the pot life after mixing? A: Pot life is generally 20–60 minutes at room temperature depending on grade and ambient conditions. Degas and dispense promptly for best results.

Q: Are flame-retardant grades available? A: Yes. We provide enhanced flame-retardant formulations for applications with stricter fire-safety requirements.

Q: How should leftover material be handled? A: Keep both components in sealed containers in a cool, dry place. Do not return partially mixed material to the original drums, as contamination can affect curing.

Q: Does part thickness affect performance? A: No. The product is not limited by thickness, giving you freedom to design thin gaskets or thick cushion blocks with consistent foam quality.
