F666 Two-Component Liquid Foam Silicone for Seals

Product Overview

Foamed Silicone Rubber is a two-component addition-curing liquid silicone designed for chemical foaming. Once Component A and B are combined, the mixture expands into a soft, lightweight, and environmentally friendly foam that can be cast at any thickness with simple handling. HONG YE SILICONE, a global supplier of RTV-2 silicone rubber and liquid silicone products, produces this foamed silicone with stable, repeatable quality for buyers in over 138 countries.

Product Features and Advantages

1. Higher Yield per Kilogram — With expansion from 2× up to 7×, you turn less silicone into more finished volume, lowering per-unit cost.
2. Consistent Cell Quality — Stable foaming with uniform cells and low linear shrinkage means reliable part dimensions and performance.
3. Lightweight with Premium Feel — Soft, elastic hand-feel without migration, collapse, or shrinkage during service.
4. Environmentally Responsible — Non-toxic, non-corrosive, non-radioactive, and chemically inert; safe even for body silicone and skin-contact uses.
5. Wide-Temperature Reliability — Retains softness and elasticity from -65°C to 200°C, with strong heat, cold, electrical insulation, and flame resistance.
6. Operator-Friendly — Simple 1:1 ratio, no thickness limits, and compatibility with both manual and automated dispensing.

How to Use — Step by Step

1. Stir each component separately before use to redistribute any settled fillers evenly.
2. Combine A and B at a 1:1 weight ratio and mix for 2–3 minutes to a uniform consistency.
3. Degas the mixture under vacuum and use it promptly to prevent premature gelling during production.
4. Pour or pump into the mold and allow foaming and curing at room temperature or with gentle heat.

Application Scenarios

• Seals and Gaskets: O-rings, sealing strips, foam sheets, silicone foam tubes, and printer roller sponges.
• Automotive and Furniture: Headrests, gear shift covers, seat cushions, sofa and mattress padding.
• Apparel and Care: Bra inserts, shoulder pads, maternity back supports, infant pillows, and senior fitness equipment.
• Model and Display: Filler for silicone robots, lifecasting figures, and prototyping — complementing mold making silicone and prototype silicone workflows.
• Electronics: Lightweight damping and filling used alongside electronic potting compound applications.

Buyer Value: Reduced raw material cost, improved product consistency, and long-lasting sealing or cushioning performance that strengthens your end-product quality.

Certifications and Compliance

Produced under ISO9001 quality management with UL and CE certifications, our foamed silicone meets recognized international safety and environmental standards, easing qualification for buyers in regulated markets.

Customization Options

Custom grades include adjustable hardness and expansion ratio, color matching, tuned viscosity for automated lines, enhanced flame-retardant versions, and food-contact or medical-grade formulations tailored to your requirements.

Production Process

Incoming raw material inspection → precision batching → vacuum mixing and degassing → lab testing of viscosity, expansion, and hardness → sealed drum packaging → final inspection before shipment. Our 48 production lines and 23+ years of experience ensure supply stability.

FAQ

Q: How consistent is the foaming quality between batches? A: We use precision batching and strict laboratory testing, so expansion ratio, cell structure, and hardness remain consistent across production batches.

Q: Can the product be colored? A: Yes. Standard pigmentation and custom color matching are available to meet your brand or application needs.

Q: Is this material suitable for food-contact products? A: We offer specialized food-grade formulations that comply with relevant contact standards. Please specify your compliance requirement when requesting a quote.

Q: What packaging sizes are available? A: Component A is packed in 25/250/200 kg drums and Component B in 20/25/200 kg drums, allowing flexible ordering for prototype and volume production.

Q: How is shipping handled? A: The product is transported as non-hazardous goods in sealed containers. Keep it in a cool, dry place away from sunlight and heat after receipt.
