Product Description

Product Summary

Insulation & flame retardant RTV Silicone Foam is a platinum-cured addition curing Foaming Silicone Rubber tailored for electrical and electronic safety scenarios. With uniform closed-cell structure, it features excellent electrical insulation, fire resistance and low-temperature non-cracking performance. Eco-friendly and inert, it is compatible with Electronic Potting Compound and Mold Making Silicone, widely used for electrical sealing, insulation filling and fireproof buffer accessories.

Product Overview

This RTV Silicone Foam is a two-component liquid Foamed Silicone, cured by heating vulcanization after A/B liquid mixing and chemical foaming. Different from ordinary Foam Silicone , it is upgraded with flame retardant and insulating formulas, retaining lightweight, soft hand feel and thickness-free molding advantages. It delivers stable physical performance, no migration or atrophy after long-term use, and maintains flexible elasticity at -65℃ to 200℃. With non-toxic, corrosion-free and chemically inert features, it perfectly matches Industrial mold silicone rubber for mass production of safety-grade industrial silicone accessories.

Core Product Features

1. Superior electrical insulation performance, effectively isolating current and preventing short circuit risks.

2. Reliable flame retardant property, inhibiting flame spread without toxic smoke release.

3. Uniform foaming structure, low linear shrinkage and excellent rebound resilience.

4. Wide temperature adaptability, stable performance in high and low temperature alternation.

5. Eco-friendly and safe, non-radioactive and chemically inert for long-term use.

Technical Specifications

Curing Type: Addition curing Platinum cured mold silicone

Mixing Ratio: 1:1 (A/B)

Foaming Multiplier: 2–7 times adjustable

Working Temperature: -65℃~200℃

Key Performance: Insulating, flame retardant, anti-aging, low shrinkage

Safety Standard: RoHS & SGS compliant

Step-by-Step Usage

1. Stir A and B components separately to eliminate storage-induced material stratification.

2. Mix two materials at 1:1 ratio and stir fully for 2–3 minutes for uniform fusion.

3. Conduct vacuum defoaming and use the mixture quickly to avoid coagulation.

4. Complete heating vulcanization and molding to obtain flame-retardant foam products.

Application Scenarios

Suitable for electrical equipment fireproof gaskets, electronic product insulation filling layers, power equipment buffer seals, new energy device safety accessories, and matched insulation parts for electronic Potting Compound molding products.

Buyer Value

Improves finished product safety compliance, reduces electrical failure and fire risks, lowers after-sales maintenance costs, and stable batch quality ensures high yield for large-scale industrial production.

Certification & Customization

Compliant with CE, RoHS, SGS and ISO9001 standards. Support customized flame retardant grade, hardness and foaming density for electrical industry demands.
