Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam) is an oil-resistant oil-contact core product, specially developed for hydraulic equipment, automotive engines 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 resistance, resistance to hydraulic oil, lubricating oil and engine oil, fine uniform closed-cell structure, good elasticity and oil stability. It has no swelling (volume change ≤1.5% after 72h oil immersion), no degradation, no oil absorption, effectively adapting to oil-contact environments, solving the problem of traditional foaming materials’ swelling in oil-contact scenarios. Compatible with most of our automotive and hydraulic products, it is ideal for oil-resistant components, oil-contact buffers and oil-contact 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 oil resistance and stability).
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 (hydraulic oil ISO VG 46) for 72h to test (volume change ≤1.5%) to confirm qualification, then use in oil-contact scenarios.
Application Scenarios
Focus on oil-contact scenarios: Hydraulic equipment oil-resistant buffers (paired with industrial mold silicone rubber), automotive engine oil-contact parts (paired with robot silicone), oil-resistant packaging (paired with Liquid Tank Silicone), hydraulic machinery components (paired with high-precision mold silicone), and oil-resistant robot parts (paired with robot silicone). It helps automotive and hydraulic industry buyers adapt to oil-contact environments and protect equipment.
Certifications and Compliance
Passed SGS eco-toxicity certification, RoHS compliant, SGS oil resistance certification, excellent oil resistance and stability, meeting the oil-resistant procurement requirements of B2B buyers in automotive, hydraulic and oil-contact industries, facilitating export to global markets.
Customization Options
Customizable oil resistance (resistant to high-temperature engine oil for high-demand scenarios), volume change (≤1.0% after 72h 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 (hydraulic oil/lubricating oil/engine oil) → immersion test → standardized curing → oil stability inspection → packaging. Strict oil testing ensures product ultra-strong oil resistance and no swelling.
