The present invention brings about an increase in the thermal conductivity of an elastomer molded article over a preexisting value. The method according to the present invention is a method that uses at least one of a liquid crystalline polymer and a precursor therefor as a thermal conductivity modifier for an elastomer. That is, the thermal conductivity modifier for an elastomer according to the present invention contains at least one of a liquid crystalline polymer and a precursor therefor. The thermal conductivity modifier may contain only at least one of a liquid crystalline polymer and a precursor therefor or may contain at least one of a liquid crystalline polymer and a precursor therefor along with an additional component. The method and thermal conductivity modifier according to the present invention can bring about an increase in the thermal conductivity of an elastomer molded article over a preexisting value.

Heat-transmitting modifier for elastomer, heat-transmission-modified crystalline elastomer, method for using crystalline polymer and precursor thereof, method for heat-transmission modification of elastomer, heater body, and heated body

A method of manufacturing and mass-producing a seamless heat-resistant resinous tube with a uniform tube wall thickness and circumference, which includes the steps of coating the precursor solution of a tube material to the surface of a core at a thickness greater than the tube wall thickness; passing a metallic die having a wider inside diameter than the diameter of the core along the outside of the core by utilizing the resistant force of the precursor solution without restricting the metallic die or the core, thus forming a tube around the core; treating the tube around the core to give it strength as a tube; and separating the tube from the core.
