Sintepon - a non-woven fabric, which retains heat well. The material has the ability to recover shape.
Sintepuh - a non-woven material consisting of a plurality of fine polyester fibers. These fibers have cavities (microscopic, water can not penetrate into them), in addition, they are well impregnated with silicone to achieve even greater flexibility. Each individual filaments twisted into a spiral and with neighboring stseplivaetsya. Through this linkage, the material becomes elastic and warm, because there are air cushions that create additional heat. Note not used in the production of adhesive and other harmful substances to form a web.
