Low Conductivity Heat Protection Silicone Sponge

Product Overview

This foamed silicone is developed for thermal management applications where ordinary insulation materials fail: moisture absorption, aging, smoke and compression collapse at high temperature. The micro-cellular structure of liquid silicone Foam traps still air to lower thermal conductivity, while the addition-cured silicone network keeps the Foam Silicone stable and elastic in hot working conditions. Compared with polyurethane foam and glass fiber that degrade or release irritants, this high-temperature-resistant Silicone Sponge is non-toxic, chemically inert and reusable, keeping insulation performance for years. With adjustable density and hardness, this RTV Silicone Foam fits into irregular gaps and complex cavities, forming effective heat insulation layers for electronic, energy and household Foaming Silicone Rubber applications.

Core Product Features & Advantages

1. Low thermal conductivity: Fine closed cells of Silicone Sponge trap still air to reduce heat transfer and save energy.
2. High-temperature resistance: Heat-resistant Foamed Silicone keeps elasticity and insulation in hot environments without melting or cracking.
3. Flame-safe insulation: Flame-retardant Foam Silicone provides an extra layer of fire protection in thermal systems.
4. Stable long-term performance: Aging-resistant Liquid Silicone Foam keeps its insulating structure under repeated heating and cooling.
5. Flexible gap filling: Soft RTV Silicone Foam fits irregular spaces and complex cavities for complete insulation coverage.
6. Safe and inert: Non-toxic, non-corrosive Addition Curing Silicone is safe for household and appliance insulation uses.

Step-by-Step Usage Instructions

1. Thorough stirring: Mix the two components of Liquid Silicone evenly for a uniform fine-cell Foaming Silicone structure.
2. Ratio blending: Combine at 1:1 ratio and stir about 3 minutes to activate the thermal insulation network.
3. Vacuum degassing: Remove air bubbles to optimize cell uniformity and insulation performance of Silicone Sponge.
4. Mold curing: Form with Mold Silicone tooling and cure to obtain heat-insulating Foamed Silicone parts.

Application Scenarios

Thermal insulation pads for new-energy battery packs and energy storage systems, pipe and duct insulation layers, electronic equipment heat protection, appliance and oven sealing gaskets, cold-chain insulation padding and high-temperature equipment protective layers. The high-stability Foamed Silicone provides reliable heat protection and energy saving for industrial and household products.

Precautions

Avoid contact with cure-inhibiting substances such as nitrogen, sulfur, phosphorus, tin, lead, cadmium and mercury; store away from direct sunlight and high-temperature baking before curing.

Packaging & Storage

25 kg sealed drums, stored dry and cool with lids closed to preserve foaming and insulation performance; shipped as non-hazardous cargo.
