What Temperature Does Silicone Rubber Melt

Neoprene also polychloroprene is a family of synthetic rubbers that are produced by polymerization of chloroprene.

What temperature does silicone rubber melt.

Neoprene is sold either as solid rubber or in latex form and is used in a wide variety of applications such as laptop sleeves orthopaedic braces wrist knee etc electrical. Rubber begins to melt at approximately 180 degrees celsius. Silicone rubbers are often one or two part polymers and may contain fillers to improve properties or reduce cost. Silicone rubber is an elastomer rubber like material composed of silicone itself a polymer containing silicon together with carbon hydrogen and oxygen silicone rubbers are widely used in industry and there are multiple formulations.

Silicone rubber has exhibits unique behavior at elevated temperatures. Neoprene exhibits good chemical stability and maintains flexibility over a wide temperature range. At high temperatures 200 450 o c silicone rubber will slowly lose its mechanical properties over time becoming brittle. Most modern shoe soles are not rubber as in natural latex based but are some form of plastic heat will melt most thermoform plastic but the problem will be making a suitable mould for the sole.

The optimum temperature for rubber is 20 c. At low temperatures around 5 c to 6 c there is a risk that rubber hardens because of crystallization. Also notice that silicone has high rubber temperature. For example if heated up to 150 c you would see very little change in the silicone even if held at this temperature for a very long time at 200 c the silicone will slowly become harder and less stretchy with time and if the silicone was heated up to a temperature beyond 300 c you would quickly see the material become harder and less.

Pure rubber once vulcanised can not be melted or the tires on your car would melt under heavy braking. After temperature cools down it resets and transforms to solid with time. This is a polymer containing silicones with atoms of oxygen carbon and hydrogen.

When adhesive silicone melts it remains intact at its place and does not flow. Silicone rubbers are usually known with the term of elastomers. The closer that your material is to the limit of your rubber temperature range the faster the material will degrade.
