HongYe silicone rubber.Our flame retardant liquid Foamed Silicone is platinum cured Addition Curing Silicone belonging to RTV Silicone Foam and Silicone Expanding Foam range, with controllable foaming ratio from 2 to 7 times original volume. Formulated with high-efficiency flame resistant ingredients, finished Silicone Sponge owns outstanding self-extinguishing performance plus wide temperature stability from -65℃ to 200℃. Widely applied in electrical insulation gaskets, new energy equipment buffer strips and automotive wiring sealing parts, it helps electronics manufacturers comply with international fire safety standards and reduce equipment fire hidden danger.
Product Overview
Flame retardant foaming silicone is two-part flowable Liquid silicone rubber, differing from ordinary industrial Mold Silicone and common Condensation Curing Silicone Mold Rubber. After A/B 1:1 mixing and heating vulcanization, chemical foaming forms uniform porous Silicone Foam . It matches the assembly demand of Silicone Potting Compound for electronic modules, serving as auxiliary filling insulation material for high-fire-risk industrial products.
Core Product Features & Advantages
Reliable flame retardant property: Self-extinguishing without continuous combustion, meeting industrial fire-proof specification.
Adjustable foaming multiple: Expand 2~7 times volume freely to realize diversified density production.
Stable physical property: Even pore distribution, low linear shrinkage, no migration or long-term shrink deformation.
Extreme temperature adaptability: Remain soft elasticity continuously at -65℃~200℃ with fine electrical insulation.
Eco inert material: Non-toxic, non-corrosive and radiation-free, safe for closed electronic component application.
Step-by-Step Usage Instructions
Pre-stirring: Stir A and B components separately to disperse stored sediment and uneven filler.
Mixing treatment: Blend raw materials at fixed 1:1 ratio, fully stir for 2-3 minutes to get homogeneous compound.
Vacuum defoaming: Pump out internal air bubbles and pour into mould rapidly to prevent early coagulation.
Heat vulcanization: Constant temperature heating to complete foaming and full curing molding.
Application Scenarios
Produce new energy battery insulation pads, electrical cabinet sealing strips, automotive wire harness foamed sleeves and household appliance fireproof cushion; coordinate with ElectronicEncapsulation Adhesive for high voltage equipment gap filling, lowering after-sale maintenance cost for electrical manufacturers.
Precautions
Avoid direct sunlight exposure and long-time high-temperature baking; isolate sulfur, tin, phosphorus, heavy metals and water to avoid incomplete curing.
Packaging & Storage
A component:25/200/250KG per barrel; B component:20/25/200KG per barrel; shipped as non-dangerous goods, sealed and stored in cool dry warehouse.
