In sealing and damping for aviation, military, electronics, and automotive, traditional solid rubber strips suffer from "hardening/cracking at high temp, losing elasticity at low temp, insufficient flame retardancy, and large compression set causing seal failure". Ordinary EVA or neoprene foam is light but narrow in temperature range (-20~80℃), dripping and fueling fire. With escalating demands for "wide temp, high flame retardancy, low compression set, long-term sealing" in 5G base stations, power batteries, and avionics, sourcing a silicone foam with "density 0.20~0.85, -60~+280℃, UL94V-0, compression set <50%" has become the core proposition. Addressing this, Anhui IOTA Silicone Oil Co., Ltd. officially launches IOTA 4801 High Elastic Foam Silicone Strip (Alias: high-temp silicone foam pad/strip, silicone sponge strip, foam silicone rubber). Characterized by "relative density 0.20~0.85±0.05g/cm³; temp -60~+280℃; insulation H grade; flame retardancy UL94V-0 & HF-1; flame spread index ASTM E162 <25; smoke density ASTM E662 <50 (4min)/<20 (1.5min); toxic gas SMP-800C PASS; colors gray/red/black/white/brown/orange (customizable); specs customizable", backed by "microcellular 3D network + high-elastic low-deformation + wide-temp flame retardancy", it serves as the "foam-shield" for aviation, electronics, and military sealing. Molecular Architecture: Silicone 3D Network + Uniform Microcellular + Halogen-Free Flame Retardant

• Silicone 3D Network: Si-O backbone (bond energy 451kJ/mol) grants extreme -60~+280℃ stability, ozone/UV/radiation resistance. Compression set <50% after 200℃/48h, far superior to organic rubber.
• Microcellular Structure: Density as low as 0.20~0.85, uniform closed/open cells provide light weight, high elasticity, and excellent sealing — blocking particles, rain, moisture, noise, while isolating vibration in electronics and vehicles.
• Halogen-Free FR System: UL94V-0 & HF-1, flame spread <25, low smoke, SMP-800C PASS. Silica formed after short-circuit combustion remains insulating, ensuring electrical continuity.

Performance Leap: From "Solid Hard Seal" to "Microcellular Elastic Seal"

• Wide-Temp Stability: No cracking at -60℃, long-term work at +280℃.
• High Elasticity Low Set: Microcells provide resilience, compression set <50% at 200℃/48h for lasting seal.
• Ultimate FR Safety: UL94V-0, low smoke non-toxic, meeting aviation, rail, nuclear standards.
• Three防 & Insulation: Water, moisture, salt fog resistance; H-grade insulation for high-voltage safety.
• Damping & Soundproofing: Cellular structure absorbs vibration and sound.

Application Penetration: From Aviation Fuel to Home Appliance Sealing

• Aviation: Fuel/lubricant pump seals, hydraulic oil seals, FR silicone parts, oxygen system seals, diaphragms, valves.
• Electronics & Telecom: TV/oscilloscope HV caps, motor stator coil insulation, switch guards, conductive rubber sheets, keyboard switches, transformer leads.
• Instruments: Oven/furnace IR heater door seals, fridge defrost wires, refrigeration seals/hoses, instrument damping.
• Military & Transport: High-speed rail door seals, ship cabin fire seals, power battery pack seals.
• Medical: Catheters, drainage tubes, silicone bionic products.
• Appliances & Printing: Fax/printer high-temp parts, automotive machinery, kitchen appliance heat transfer equipment.

IOTA Technical Guide: Custom Color/Spec, Avoid Sun & Oil

• Customization: Colors customizable except red/gray/natural/white/black; specs per customer request.
• Taboo: Avoid sharp metal contact to prevent puncture; store in cool ventilated place, avoid sun and oil.
• Storage: Non-hazardous, routine transport.

Industry Insight: Domestic breakthroughs in silicone foam uniformity and halogen-free FR enable IOTA 4801 to fill the key supply chain link for domestic high-elastic foam silicone in aviation, electronics, and military sealing, providing import-substitution with "density 0.20~0.85 + UL94V-0 + -60~+280℃ + H-grade insulation". This confirms domestic specialty silicones are leaping toward "microcellular elastic FR foam", with growing technical say in extreme environment sealing.
