Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam ) is a high-tear-strength core product, focusing on durability and anti-tearing performance. As a 2-component addition curing silicone, it is formed by chemical foaming of flowable Part A and Part B, formulated with high-toughness components, featuring ultra-high tear strength, fine uniform pore structure, good elasticity and excellent durability. It can withstand repeated stretching and friction without tearing or breaking, effectively extending the service life of products. Compatible with most of our core products, it is ideal for high-wear, high-stress scenarios requiring long-term stable use.

Product Features & Advantages
1. Ultra-High Tear Strength: Tear strength up to 15 kN/m, much higher than traditional foaming silicone (8-12 kN/m), strong toughness, can withstand repeated stretching and friction without tearing, solving the problem of traditional foaming materials’ poor tear resistance and short service life.
2. Excellent Durability: No easy aging, no brittle fracture, no performance degradation after long-term use, service life is 3-4 times that of ordinary foaming silicone, reducing replacement costs for buyers.
3. Tear Strength & Elasticity Balance: While maintaining high tear strength, it retains good elasticity and flexibility, can adapt to irregular shapes and frequent deformation, ensuring performance without losing flexibility.
4. Durability Compatibility: Compatible with HONG YE SILICONE’s industrial Mold Silicone rubber and robot silicone, forming a complete durable solution, enabling one-stop procurement for high-durability buyers. 5. Easy Operation: 1:1 simple mixing ratio, good flowability, easy to process into various durable components, no professional 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 tear strength and durability).
2. Mix and stir thoroughly for 2-3 minutes until homogeneous, vacuum degas to remove air bubbles (ensure tear strength uniformity and product performance).
3. Pour the mixture into the mold or gap (paired with industrial mold silicone rubber), foam and cure at room temperature or by heating.
4. After full curing, the product has high tear strength and durability, can be directly used in high-wear, high-stress scenarios.
Application Scenarios
Focus on high-durability scenarios: Industrial high-wear components (paired with industrial mold silicone rubber), robot moving parts (paired with robot silicone), automotive wear-resistant sealing (paired with industrial mold silicone rubber), electronic component durable protection (paired with Electronic Potting Compound), and high-stress filling parts (paired with Liquid Tank Silicone). It helps high-durability buyers improve product service life and reduce maintenance costs.
Certifications and Compliance
Passed SGS eco-toxicity certification, RoHS compliant, excellent tear strength and durability, meeting the high-durability procurement requirements of B2B buyers in various industries, facilitating export to global durable product markets.
Customization Options
Customizable tear strength (up to 20 kN/m for high-demand scenarios), foaming ratio, hardness and viscosity, adapting to different wear and stress requirements, helping buyers optimize product durability.
Production Process
High-tear-strength-oriented production process: High-purity high-toughness Silicone raw materials → formula optimization (enhance tear strength) → precision mixing → tear strength test → standardized curing → durability inspection → packaging. Strict tear strength control ensures the durability of each batch.
