Thermal Conductivity Of Rubber Compounds

The device is presented and the calculations in order to obtain samples with controlled and homogeneous vulcanization rates are performed.

Thermal conductivity of rubber compounds.

Lasance articles design materials compounds adhesives substrates test measurement elastomer rubber technical data thermal conductivity in the may 2001 issue this column discussed the thermal conductivity of unfilled plastics. Very high thermal conductivity measurements up to 22 600 w m 1 k 1 were reported by fenton e w rogers j s. November 1 2001 clemens j. Consequently there is a vast potential for optimization of.

Vulcanization rate was found to have a significant impact on the thermal conductivity of the product thermal conductivity of rubber compounds versus the. An uncured sample was also obtained for use as a reference. The hot disk tps was chosen to perform the measurements due to its fast test times and non destructive method of testing. Due to the low thermal conductivity of rubber compounds typically in the range from 0 15 to 0 4 w m 1 k 1 and the fact that the molding of the rubber part takes place in a heated mold via an energy based crosslinking reaction the total cycle time is in the range of minutes.

2012 manipulated the curing process to produce rubber samples that had been produced with different vulcanization rate. The thermal conductivity of each of the samples was measured using the hot disk transient plane source 2500s the thermal conductivity analyzer hot disk tps 2500s is state of the art thermal. The hot disk technique is used to measure the thermal conductivity of the rubber. The thermal conductivity of a rubber compound is studied as a function of its state of curing.
