Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam ) is a low-volatility low outgassing core product, specially developed for high-vacuum environments, electronic equipment and low-volatility scenarios. As a 2-component addition curing silicone, it is formed by chemical foaming of flowable Part A and Part B, formulated with low-volatility raw materials and anti-outgassing agents, featuring ultra-low volatility, low outgassing, fine uniform closed-cell structure, good elasticity and volatility stability. It has a volatility of ≤0.5%, no harmful volatiles, low outgassing, effectively avoiding contamination of surrounding components, solving the problem of traditional foaming materials’ high outgassing in high-vacuum scenarios. Compatible with most of our electronic and high-vacuum products, it is ideal for low-volatility components, low-outgassing buffers and high-vacuum scenarios.

How to Use
1. Take Part A and Part B according to 1:1 weight ratio, stir separately to eliminate sediment, ensure no impurities (avoid affecting volatility and low outgassing).
2. Mix and stir thoroughly for 3 minutes until homogeneous, vacuum degas to remove air bubbles (ensure low volatility uniformity and closed-cell structure, avoid volatile accumulation).
3. Pour the mixture into low-volatility component mold (paired with electronic potting compound), foam and cure at room temperature or by heating (heating helps reduce residual volatiles).
4. After full curing, the product has low volatility and low outgassing, ready for use in high-vacuum and electronic equipment scenarios.
Application Scenarios
Focus on low-volatility scenarios: High-vacuum equipment buffers (paired with electronic potting compound), electronic component low-outgassing parts (paired with high-precision mold silicone), low-volatility packaging (paired with Liquid Tank Silicone), aerospace low-outgassing components (paired with robot silicone), and low-volatility robot parts (paired with robot silicone). It helps low-volatility industry buyers avoid component contamination and ensure product stability.
Certifications and Compliance
Passed SGS eco-toxicity certification, RoHS compliant, SGS volatility certification, excellent low volatility and low outgassing, meeting the low-volatility procurement requirements of B2B buyers in electronic, aerospace and high-vacuum industries, facilitating export to global markets.
Customization Options
Customizable volatility (≤0.3% for high-demand scenarios), outgassing rate (≤0.05%/h for high-demand scenarios), foaming ratio and hardness, adapting to different low-volatility and high-vacuum requirements, helping buyers optimize low-outgassing effect.
Production Process
Low-volatility-oriented production process: High-purity low-volatility Silicone raw materials → formula optimization (add anti-outgassing agents) → precision mixing → volatility test → outgassing rate test → standardized curing → residual volatile inspection → packaging. Strict volatility testing ensures product ultra-low volatility and low outgassing.
