Product Summary

HONG YE SILICONE’s Liquid Foamed Silicone is a high-temperature resistant 2-component addition curing silicone, featuring exceptional high-temperature stability (long-term use at 250℃, short-term resistance up to 300℃), no aging, no deformation, no performance degradation under high temperature. It has fine uniform closed-cell pores, -65℃-250℃ temperature range, 1:1 easy operation, passed SGS high-temperature certification, compatible with high-temperature insulation silicone and industrial mold silicone rubber, serving B2B buyers in high-temperature working scenarios.

Product Overview

HONG YE SILICONE’s Liquid Foamed Silicone (foaming silicone rubber, silicone foam) is a high-temperature resistant core product, specially developed for harsh high-temperature environments. As a 2-component addition curing silicone, it is formed by chemical foaming of flowable Part A and Part B, formulated with high-temperature resistant silicone raw materials and heat-stabilizing components, featuring excellent thermal stability, fine uniform closed-cell structure, good elasticity and high-temperature durability. It can maintain stable performance even in long-term high-temperature operation (250℃), no brittle fracture, no volume change, no harmful gas release, effectively protecting high-temperature equipment and components. Compatible with most of our high-temperature series products, it is ideal for high-temperature filling, sealing and protection scenarios.

Product Features & Advantages

1. Exceptional High-Temperature Resistance: Long-term use at 250℃, short-term resistance up to 300℃, much higher than traditional foaming silicone (200℃ max), solving the problem of traditional materials’ easy aging and deformation under high temperature.

2. Superior Thermal Stability: No volume change, no brittle fracture, no performance degradation after long-term high-temperature exposure, thermal stability lasting, ensuring long-term protection of high-temperature equipment.

3. High-Temperature & Safety Balance: High-temperature resistance while ensuring no harmful gas release, non-toxic, safe for high-temperature working environments, meeting high-safety standards for high-temperature scenarios.

4. High-Temperature Compatibility: Compatible with HONG YE SILICONE’s high-temperature insulation silicone and industrial mold silicone rubber, forming a complete high-temperature protection solution, enabling one-stop procurement for high-temperature buyers.

5. Easy Operation: 1:1 simple mixing ratio, good flowability, easy to process into high-temperature components, no professional high-temperature operation skills required, improving production efficiency.

How to Use

1. Take Part A and Part B according to 1:1 weight ratio, stir separately to eliminate sediment, ensure no impurities (avoid affecting high-temperature stability).

2. Mix and stir thoroughly for 2-3 minutes until homogeneous, vacuum degas to remove air bubbles (ensure high-temperature uniformity and closed-cell structure).

3. Pour the mixture into high-temperature equipment mold or gap (paired with high-temperature insulation silicone), foam and cure at room temperature or by heating (100℃ for 1h).

4. After full curing, the product can be directly used in high-temperature scenarios, maintaining stable performance at 250℃, no aging or deformation.

Application Scenarios

Focus on high-temperature scenarios: High-temperature industrial equipment sealing (paired with industrial mold silicone rubber), high-temperature insulation filling (paired with high-temperature insulation silicone), automotive engine components (paired with industrial mold silicone rubber), high-temperature electronic protection (paired with electronic potting compound), and high-temperature robot parts (paired with robot silicone). It helps high-temperature buyers protect equipment from high-temperature damage and ensure stable operation.

Certifications and Compliance

Passed SGS eco-toxicity certification, RoHS compliant, SGS high-temperature certification, excellent high-temperature resistance and thermal stability, meeting the procurement requirements of B2B buyers in high-temperature, industrial and automotive industries, facilitating export to global high-temperature markets.

Customization Options

Customizable high-temperature resistance (long-term up to 300℃ for high-demand scenarios), foaming ratio, hardness and viscosity, adapting to different high-temperature working requirements, helping buyers optimize product high-temperature performance.

Production Process

High-temperature-oriented production process: High-purity high-temperature resistant silicone raw materials → formula optimization (add heat-stabilizing components) → precision mixing → high-temperature performance test (250℃ long-term) → standardized curing → thermal stability inspection → packaging. Strict high-temperature testing ensures product adaptability to harsh high-temperature environments.
