There is not a single melting point for these substances so using the term softening applies more closely to the super heating of rubber tires.
Rubber melting point.
Nbr is used in the automotive and aeronautical industry to make fuel and oil handling hoses seals grommets.
This rubber o ring temperature chart shows high and low rubber temperature range resistance for all popular materials.
Some of these are effective in production for example vulcanization accelerators while others play an important role in the finished product e g.
Pure rubber once vulcanised can not be melted or the tires on your car would melt under heavy braking.
The rubber used in creating tires is a mixture of many compounds including carbon latex rosin and chalk hardened by the addition of sulfur and other compounds.
Neoprene exhibits good chemical stability and maintains flexibility over a wide temperature range.
In rubber manufacture different chemical substances are added to the polymer mass.
What is the melting point of rubber.
Importance of the melting point of rubber chemicals.
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.
Rubber begins to melt at approximately 180 degrees celsius.
Nitrile rubber also known as nbr buna n and acrylonitrile butadiene rubber is a synthetic rubber derived from acrylonitrile acn and butadiene.
Neoprene also polychloroprene is a family of synthetic rubbers that are produced by polymerization of chloroprene.

It is a question silicone engineering get asked frequently by engineers and designers who are looking for an exact temperature point where silicone rubber will start to degrade in application.
Melting points and flame colours o r denote oxidizing and reducing conditions respectively.
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.
In the majority of cases there isn t a definitive answer that our experts can give without discussing further about the environment that the silicone.
Make sure that your material is compatible with your environment by going to our rubber properties and chemical compatibility sections.
