What temperature can a silicone hose withstand?

Silicone hose is very popular for its resistance to extreme temperatures. Silicone has a high heat-carrying capacity, is not easy to melt, and has high heat resistance. Most silicones have a working temperature range of -60°C to +250°C. Making it suitable for various industrial applications involving extreme temperatures.

There are special types of silicone that can withstand a wider temperature range. High-temperature silicone rubber can withstand temperatures up to +300°C.

How hot can silicone tubing get before it melts?
The first thing you’ll notice is that the silicone tubing won’t melt due to temperature alone!

For example, if you heat it to 150°C, you will find that the silicone tubing shows little change, even if you keep it at this temperature for a long time, at 250°C, the silicone tubing will change over time. Slowly hardening and reducing elasticity, although the melting point and ignition point of the material are usually not reached in most automotive applications, the effect of high temperature on silicone tubing does exist. With prolonged high temperatures, it will slowly lose its mechanical properties and become brittle.

Why is the silicone hose heat-resistant?

Silicone has low thermal conductivity. This means it transfers heat much more slowly than some other materials, giving it excellent heat resistance. It can also be described as having good “thermal stability,” meaning it retains its structure and properties over a wide range of temperatures.

Its heat resistance largely depends on the highly stable chemical structure of the material. The backbone of siloxane is a stable structure that does not allow the material to degrade in the presence of heat. With such outstanding properties, it’s no wonder that silicone has such a wide range of applications and uses.

Silicone rubber is a new type of polymer elastic material, which has excellent high-temperature resistance (250-300°C) and low-temperature resistance (-40-60°C), good physiological stability, and can withstand repeated harsh conditions. And disinfection conditions, with excellent resilience and small permanent deformation, breakdown voltage (20-25KV/mm), ozone resistance, and UV resistance. Radiation resistance and other characteristics, special silicone rubber has oil resistance
