Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam ) is a low permeability sealing core product, specially developed for sealing, impermeable and no-leakage scenarios. As a 2-component addition curing silicone, it is formed by chemical foaming of flowable Part A and Part B, formulated with low-permeability additives and dense structure design, featuring ultra-low gas permeability, high sealing performance, fine uniform closed-cell structure, good elasticity and sealing stability. It has a gas permeability of ≤5 cm³/(m²·24h·atm), can effectively block gas and liquid penetration, no leakage, effectively solving the problem of traditional foaming materials’ high permeability and poor sealing performance. Compatible with most of our industrial and storage products, it is ideal for sealing components, impermeable equipment and no-leakage 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 permeability and sealing performance).
2. Mix and stir thoroughly for 3 minutes until homogeneous, vacuum degas to remove air bubbles (ensure low permeability and dense sealing structure).
3. Pour the mixture into sealing component mold (paired with liquid tank silicone), foam and cure at room temperature or by heating for better sealing effect.
4. After full curing, the product has low permeability and high sealing, no leakage, ready for use in sealing and impermeable scenarios.
Application Scenarios
Focus on sealing scenarios: Industrial equipment seals (paired with industrial mold silicone rubber), liquid storage tank sealing (paired with liquid tank silicone), gas cylinder sealing (paired with high-precision mold silicone), sealing robot parts (paired with robot silicone), and electronic equipment waterproof sealing (paired with Electronic Potting Compound). It helps sealing-industry buyers reduce leakage risks and ensure equipment integrity.
Certifications and Compliance
Passed SGS eco-toxicity certification, RoHS compliant, SGS permeability certification, excellent low permeability and high sealing performance, meeting the sealing procurement requirements of B2B buyers in industrial, storage and electronic industries, facilitating export to global markets.
Customization Options
