PURPOSE: To provide a far infrared radiator which permits ready preparation of a product having a large radiation area by the use of a small amt. of a raw material, is so flexible that cutting, etc., are facile, does not break when let fall and is free from water absorption and bacterium invasion, and which comprises a synthetic rubber and, blended therein, a powdery ceramic material capable of radiating far infrared rays.
CONSTITUTION: A fine powder of a ceramic material capable of radiating far infrared rays is blended in a synthetic rubber in the blending step of the synthetic rubber manufacturing process, and subjected to procedures similar to those customary for preparing sheet-form synthetic rubbers, thereby obtaining a sheet-form far infrared radiator comprising the synthetic rubber and, blended therein, fine powder of the ceramic material. Due to the sheet form, the far infrared radiator provides a large radiation area by the use of a small amt. of a raw material. Also, the radiator can be cut or blanked into any desirable size and shape with extreme readiness. The radiator does not break when let fall, and is hygienic since it is free from water absorption and bacterium invasion. The radiator has high heat resistance, so that a radiator article stable at a temp. as high as about 200°C can be produced.
