Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam ) is a low-temperature resistant core product, specially developed for low-temperature, ultra-low temperature and frost-prone scenarios. As a 2-component addition curing silicone, it is formed by chemical foaming of flowable Part A and Part B, formulated with low-temperature resistant components, featuring ultra-low temperature resistance, frost-resistant, fine uniform closed-cell structure, good elasticity and low-temperature stability. It can withstand long-term use at -80℃, short-term exposure to -100℃, no brittle fracture, no cracking, no performance degradation, effectively protecting equipment and components from low-temperature and frost damage. Compatible with most of our high-temperature and industrial products, it is ideal for low-temperature industrial, aerospace and cold-chain scenarios.

Product Features & Advantages
1. Ultra-Low Temperature Resistance: Long-term use at -80℃, short-term up to -100℃, lower than traditional foaming silicone (-65℃ max), solving the problem of traditional materials’ poor low-temperature resistance and brittle fracture.
2. Frost-Resistant Performance: Frost-proof, no brittle fracture, no cracking in frost-prone environments, adapting to harsh low-temperature conditions.
3. Low-Temperature & Elasticity Balance: While maintaining ultra-low temperature resistance, it retains good elasticity and structural stability, no brittle fracture at ultra-low temperature, balancing low-temperature protection and usability.
4. Compatibility with Low-Temperature Products: Compatible with HONG YE SILICONE’s high-temperature insulation silicone and industrial Mold Silicone rubber, forming a complete low-temperature protection solution, enabling one-stop procurement. 5. Easy Operation: 1:1 simple mixing ratio, good flowability, easy to process into low-temperature components, no professional low-temperature operation skills required, improving production efficiency.
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 low-temperature performance).
2. Mix and stir thoroughly for 2-3 minutes until homogeneous, vacuum degas to remove air bubbles (ensure low-temperature uniformity and closed-cell structure).
3. Pour the mixture into low-temperature component mold (paired with high-temperature insulation silicone), foam and cure at room temperature or by heating.
4. After full curing, the product can be directly used in low-temperature and ultra-low temperature scenarios, no brittle fracture, no degradation.
Application Scenarios
Focus on low-temperature scenarios: Low-temperature industrial equipment sealing (paired with industrial mold silicone rubber), aerospace ultra-low temperature components (paired with high-temperature insulation silicone), cold-chain packaging parts (paired with Liquid Tank Silicone), frost-resistant robot parts (paired with robot silicone), and low-temperature electronic protection (paired with Electronic Potting Compound). It helps low-temperature buyers protect equipment from low-temperature and frost damage.
Certifications and Compliance
Passed SGS eco-toxicity certification, RoHS compliant, SGS low-temperature certification, frost-resistant certification, excellent low-temperature and frost-resistant performance, meeting the low-temperature procurement requirements of B2B buyers in industrial, aerospace and cold-chain industries, facilitating export to global markets.
