Tire rubber melting temperature.

The rubber in tires is vulcanized meaning that is in fact one big molecule. A common method is to chop the tires into half inch pieces and mix the pieces with liquid nitrogen at a temperature of minus 148 degrees fahrenheit minus 100 degrees celsius. Total tire recycling using proprietary and patented process. Tire temperatures are the easiest and most cost effective link you have to the action at the tire contact patch.

It will not melt. Scientists have figured out that for every 10 degrees fahrenheit that the temperature rises the tire pressure will increase by one pound per square inch psi. When heated to a high enough temperature in an inert atmosphere away from air oxygen the rubber will decompose sometimes partially resulting in an oily ooze. 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.

It doesn t sound like much but there s typically only 30 35 psi in the tires of passenger vehicles. 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 begins to melt at approximately 180 degrees celsius. 220 268 432 488 polyethylene ld.

At low temperatures around 5 c to 6 c there is a risk that rubber hardens because of crystallization. The air pressure in tires increases as the temperature goes up. The optimum temperature for rubber is 20 c. At ambient temperature old tires can be turned into crumb rubber.

Melting points and ignition temperatures. Americans discard approximately 100 million tires every year which begs some type of recycling method to prevent overloading landfills. Pure rubber once vulcanised can not be melted or the tires on your car would melt under heavy braking.
