さとしては、３〜8mm程度のものが好ましい。Elastomer fiber blended with this has an elongation of 500% or more,
It has an elastic recovery rate of 90 to 99%. Elastomer fibers with an elongation of 500% or less do not provide the desired large tear strength, elastic recovery rate of 90% or more, and because the elastomer-blended silicone composition is heat-crosslinked to form a product, the temperature of 150 ° C It is desirable to withstand one hour or more. Examples of elastomer fibers that can be used include polyurethane fibers, nitrile rubber fibers, polybutadiene-styrene fibers, polyamide elastic fibers, polyester elastic fibers,
Polyurethane elastomer fibers are particularly preferred. The thickness of the fiber is preferably in the range of about 10 to 1000 denier, and when using 10 denier or less, it is difficult to disperse it in the silicone rubber solution, and when it is 1000 denier or more, it is on the surface of the human body model as a product. It is not preferable because it shows unevenness. Usually around 50 denier is used. The fiber length is preferably about 3 to 8 mm.

る量を配合してもさほど改善されない。The blending amount of the elastomer fiber is about 1 per 100 parts by weight of the silicone rubber in view of the smooth appearance of the sheet surface.
It is preferably about 20 to 20 parts by weight, particularly about 8 parts by weight. If it is less than 1 part by weight, the intended purpose cannot be achieved, and if it is compounded in an amount exceeding 20 parts by weight, it is not so much improved.
