Product Abstract
HongYe silicone rubber.High Temperature Resistant Foaming Silicone Rubber is specialized RTV liquid silicone foam made of Platinum cured mold silicone, categorized as industrial-grade Foaming SiliconeRubber with stable foaming effect between -65℃~200℃. Its finished Silicone Sponge retains stable elasticity under continuous high-temperature working condition with superior flame retardancy and insulation. Mainly used for high-heat equipment sealing strip, oven cushion and automotive engine peripheral shock pads, helping buyers solve high-temperature aging problem of traditional foaming rubber and extend component service life.
Product Overview
This high-temperature resistant Foamed Silicone is double-component addition curing liquid foamed silicone, developed targeting harsh high-temperature industrial working environment, different from regular LiquidSilicone Foam. After A/B liquid blending and thermal vulcanization foaming, formed porous silicone foams own excellent thermal stability, becomes preferred raw material for high-temperature sealing parts, also matches electronic potting auxiliary filling alongside Silicone Potting Compound application.
Core Product Features & Advantages
Outstanding thermal stability: Long-term stable elasticity within -65℃~200℃, no softening or collapse under lasting high heat.
Excellent flame retardant & insulation: Good electrical insulation, self-extinguishing property, fit electric equipment auxiliary sealing.
Consistent foaming stability: Fixed foaming ratio, uniform pores, finished size controllable for standardized batch production.
Anti-aging & anti-shrink: No atrophy after long-term high-temp usage, avoid frequent part replacement.
Safe inert material: Non-toxic chemical composition, no corrosion to metal and plastic mating parts.
Step-by-Step Usage Instructions
Separate stirring: Fully agitate A and B raw materials respectively to eliminate standing layering.
Ratio mixing: Mix A:B=1:1, stir uniformly for 2-3 minutes.
Vacuum processing: Remove inner air bubbles via vacuum, implement mould filling quickly.
Heating vulcanization: Constant temperature curing to finish chemical foaming and shaping.
Application Scenarios
Produce high temp resistant sealing gasket, industrial oven silicone foamed tube, auto high-temperature buffer pad; cooperate with ElectronicEncapsulation Adhesive for electronic module gap filling. Industrial manufacturers use this product to improve high-temperature equipment safety and lower after-sales maintenance expense.
Precautions
Avoid sun exposure and overheating storage; isolate sulfur, heavy metal substances and water to prevent incomplete foaming curing.
Packaging & Storage
Multiple barrel specs:20/25/200KG, non-dangerous goods shipment, sealed cool dry preservation.
