Top choice for extreme cold sealing materials in silicone and rubber/plastic product manufacturing

I. Product Overview

Ningdao Rubber's ultra-low-temperature silicone rubber, engineered for extreme cold conditions with a specialized organic silicon formula.Product does not crystallizeMaintains excellent resilience at 55°C and retains full usability down to 70°C, with a minimum temperature limit of-105℃Perfectly solves the problems of low-temperature brittleness and seal failure in standard silicone.

Meets ASTM international testing standards; core performance matches leading imported brands. Requires no formula changes or mold replacements for seamless substitution. Supports personalized customization of hardness, temperature resistance, oil resistance, and color. Ideal core material for low-temperature sealing components in aerospace, automotive, petrochemical, defense, and cold chain industries.
