Product Overview
liquid silicone Foam – HighPerformance, EcoFriendly Expansion Material for Industrial & Consumer Applications
HONG YE JIE’s Liquid Silicone Foam is a premium, platinumcured, twopart additiontype silicone rubber designed for highefficiency foaming applications. This advanced RTV Silicone Foam expands up to 7 times its original volume with uniform cell structure, offering exceptional softness, lightweight feel, and superior durability. Ideal for rapid prototyping, mold making, and functional components, it replaces traditional polyurethane and foam materials with a safer, more sustainable alternative. Trusted globally across industries including automotive, medical, electronics, and consumer goods, our Foamed Silicone delivers consistent performance under extreme temperatures (65°C to +200°C), excellent electrical insulation, flame resistance, and zero migration or shrinkage.
As a core product in our Mold Making Silicone Rubber, Addition Curing Silicone, and Food grade mold silicone portfolio, this liquid foam is FDAcompliant and environmentally safe—perfect for healthcare devices, baby products, and foodcontact applications. With over 15 years of export experience and ISO9001/CE/UL certifications, HONG YE JIE ensures reliable quality and scalability for B2B buyers worldwide.

How to Use – StepbyStep Guide
1. PreMix: Stir each component (A & B) thoroughly before use to avoid uneven distribution.
2. Mix Ratio: Combine A and B in a 1:1 weight ratio. Mix for 2–3 minutes until fully homogenized.
3. Degassing: Vacuum degas for 1–2 minutes to eliminate air bubbles.
4. Pour & Cure: Pour into mold or cavity; cure at 150°C for 45 minutes.
5. PostCure: Optional extended cure (180°C, 2 hours) enhances thermal and mechanical properties.
⚠️ Do Not: Expose to UV light, high heat (>200°C), or contact with sulfur, nitrogen, tin, lead, mercury, or waterbased contaminants.

FAQ
Q: Is this liquid silicone foam safe for medical use?
Q: Can I use it for foodcontact products?
A: Absolutely — the Food Grade Mold Silicone version is FDAcompliant and nontoxic.
Q: What’s the difference between your liquid foam and PU foam?
A: Unlike polyurethane, our Foam Silicone doesn’t degrade, emit odors, or cause allergies; it’s recyclable and far more durable.
Q: How long does it take to cure?
A: Full cure in 45–60 minutes at 150°C; faster with higher temperatures.
Q: Do you support small orders?
A: Yes — we accept MOQs starting from 5 kg, ideal for startups and prototyping projects.
