3. Cold Resistance & Versatility Balance: While maintaining excellent cold resistance, it can also withstand high temperature (200℃ long-term), wide temperature range, suitable for both low and high temperature scenarios, improving versatility.
4. Compatibility with Core Products: Compatible with HONG YE SILICONE’s high-temperature insulation silicone and industrial Mold Silicone rubber, forming a complete low-temperature protection solution, enabling one-stop procurement. 5. Easy Operation: 1:1 simple mixing ratio, good flowability, easy to process into low-temperature components, no professional cold-resistant 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 cold-resistant performance).
2. Mix and stir thoroughly for 2-3 minutes until homogeneous, vacuum degas to remove air bubbles (ensure cold-resistant uniformity and closed-cell structure).
3. Pour the mixture into low-temperature component mold (paired with high-temperature insulation silicone), foam and cure at room temperature or by heating.
4. After full curing, the product can be directly used in low-temperature scenarios (-80℃ long-term), maintaining flexibility and stable performance, no brittle fracture.
Application Scenarios
Focus on low-temperature scenarios: Low-temperature industrial equipment sealing (paired with industrial mold silicone rubber), ultra-low-temperature insulation filling (paired with high-temperature insulation silicone), automotive low-temperature parts (paired with industrial mold silicone rubber), low-temperature electronic protection (paired with Electronic Potting Compound), and low-temperature robot components (paired with robot silicone). It helps low-temperature buyers protect equipment from cold damage and ensure stable operation.
Certifications and Compliance
Passed SGS eco-toxicity certification, RoHS compliant, SGS cold-resistant certification, excellent cold resistance and low-temperature flexibility, meeting the low-temperature procurement requirements of B2B buyers in industrial, automotive and electronic industries, facilitating export to global low-temperature markets.
Customization Options
Customizable cold resistance (long-term up to -100℃ for high-demand scenarios), low-temperature flexibility, foaming ratio and hardness, adapting to different low-temperature requirements, helping buyers optimize product low-temperature performance.
Production Process
Low-temperature-oriented production process: High-purity cold-resistant Silicone raw materials → formula optimization (add cold-resistant and flexible components) → precision mixing → cold-resistant performance test (-80℃ long-term) → standardized curing → low-temperature flexibility inspection → packaging. Strict cold-resistant testing ensures product adaptability to ultra-low-temperature environments.
