Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam) is an oil-resistant & grease-resistant anti-swelling core product, specially developed for oil-contacting equipment, automotive components and oil-contact scenarios. As a 2-component addition curing silicone, it is formed by chemical foaming of flowable Part A and Part B, formulated with oil-resistant modifiers and anti-swelling agents, featuring ultra-strong oil and grease resistance, no swelling, no oil absorption, fine uniform closed-cell structure, good elasticity and oil stability. It has no swelling, volume change ≤0.8% after 72h oil immersion, effectively resisting oil and grease erosion, solving the problem of traditional foaming materials’ swelling in oil-contact scenarios. Compatible with most of our oil-contact and automotive products, it is ideal for oil-resistant components, oil-contact buffers and oil-contact scenarios.

Compatibility with Oil-Contact Products: Compatible with HONG YE SILICONE’s industrial Mold Silicone rubber and robot silicone, forming a complete oil-resistant solution, enabling one-stop procurement. 5. Easy Operation: 1:1 simple mixing ratio, good flowability, easy to process into oil-resistant components, no professional oil-resistant 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 oil resistance and anti-swelling).
2. Mix and stir thoroughly for 3 minutes until homogeneous, vacuum degas to remove air bubbles (ensure uniform oil resistance and closed-cell structure, no oil penetration).
3. Pour the mixture into oil-resistant component mold (paired with industrial mold silicone rubber), foam and cure at room temperature or by heating (heating helps enhance oil stability).
4. After full curing, immerse in oil for 72h to test (volume change ≤0.8%) to confirm qualification, then use in oil-contact scenarios.
Application Scenarios
Focus on oil-contact scenarios: Oil-contacting equipment oil-resistant buffers (paired with industrial mold silicone rubber), automotive component oil-contact parts (paired with robot silicone), oil-resistant packaging (paired with Liquid Tank Silicone), oil machinery components (paired with high-precision mold silicone), and oil-resistant robot parts (paired with robot silicone). It helps automotive and oil-contact industry buyers protect equipment from oil and grease erosion.
Certifications and Compliance
Passed SGS eco-toxicity certification, RoHS compliant, SGS oil resistance test certification, excellent oil and grease resistance, meeting the oil-resistant procurement requirements of B2B buyers in automotive, oil-contact and machinery industries, facilitating export to global markets.
Customization Options
Customizable oil resistance (resistant to high-temperature oil for high-demand scenarios), volume change (≤0.5% after 72h oil immersion for high-demand scenarios), foaming ratio and hardness, adapting to different oil-contact requirements, helping buyers optimize oil-resistant effect.
Production Process
Oil-resistant-oriented production process: High-purity oil-resistant Silicone raw materials → formula optimization (add oil-resistant modifiers and anti-swelling agents) → precision mixing → oil resistance test → immersion test → standardized curing → oil stability inspection → packaging. Strict oil testing ensures product ultra-strong oil and grease resistance and no swelling.
