Abstract: A material with high thermal conductivity for insulating electronic parts is formed by exposure to a compressive shearing force of a compound containing 50 to 95% by volume heat conductive, inorganic powder and 5 to 50% by volume bonding agent. The bonding agent contains at least 0.2 to 30% by volume polytetrafluoroethylene (PTFE), preferably 1.0 to 20%, and synthetic rubber, where the volume ratio of rubber is 1/4 or more of the PTFE. The compressive shearing force fibrillates the PTFE and disperses the inorganic powder so that there is an even aggregation of heat conductive material. Other ingredients such as vulcanizing agents, vulcanizing accelerators, stabilizers, processing aids, flame retardents, coloring agents, and solvents may be added. The material may be reinforced with a woven or non-woven fabric or staple fibers.

Abstract: A method of producing a shoulder pad blank having a thick-walled portion and a thin-walled portion comprising cutting a sheet of shoulder pad stock material sinusoidally into two intermediate blanks each having a plurality of ridges spaced a predetermined distance from each other, and then cutting the ridges sinusoidally along their length.
