SILICONE RUBBER COMPOSITION RADIATING FAR INFRARED RAY

摘要

PURPOSE: A silicone rubber composition radiating a far infrared ray is provided, to prevent the deterioration of the thermal conductivity and the insulating property due to the generation of pin hole. CONSTITUTION: The silicone rubber composition comprises a silicone rubber; a curing agent; a coloring agent; and at least one powder selected from the group consisting of ferrite powder, jade powder, SiO2 powder and elvan powder, as a far infrared ray-radiating material, in the ratio of 60-90 : 5-35 : 1-2 : 3-4 by weight. Preferably the ratio of ferrite powder and SiO2 powder is 60-80 : 20-40 by weight; the ratio of ferrite powder, SiO2 powder and jade powder is 60-80 : 10-20 : 10-20 by weight; and the ratio of SiO2 powder, jade powder and elvan powder is 60-80 : 7-15 : 6-10 by weight.
