Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam) is a heavy oil-resistant core product, specially developed for oil-contact equipment, automotive components and oil-resistant 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, no swelling, no oil absorption, fine uniform closed-cell structure, good elasticity and oil-resistant stability. It is resistant to engine oil, hydraulic oil, lubricating oil and other heavy oils, volume change ≤1% after 72h oil immersion, no performance degradation, effectively resisting oil erosion, solving the problem of traditional foaming materials’ swelling and oil absorption in oil-contact scenarios. Compatible with most of our oil-resistant products, it is ideal for oil-resistant components, oil-contact buffers and oil-resistant scenarios.
