Thinsulate
Thinsulate is a trademark of 3M Corporation for a heat-insulating nonwoven fabric made from man-made fibers , which is mainly used as an insert for clothing , e.g. B. gloves or winter jackets is used. The word is a compound term from (English) thin & insulate (German: thin & dämmen). The material was first launched in 1979.
properties
Thinsulate fibers have a diameter of around 15 micrometers (microns), making them finer than ordinary polyester fibers and should therefore be able to be processed with a higher density. As with all insulation materials, the space between the fibers reduces the (out) flow of heat, so that a pleasant amount of heat is retained while moisture, such as sweat , can escape.
The manufacturer states that - with the same fabric thickness - Thinsulate insulates once or twice as well as goose down , while it absorbs much less water and is also elastic .
Thinsulate nonwovens are made from various polymer blends. Mostly it is mainly polyethylene terephthalate (PET) or a mixture of it with polypropylene (PP). Other grades sometimes also contain polyethylene terephthalate-polyethylene isophthalate copolymer and modacrylic fibers .
Thinsulate is also used in the inner roof cover of the youngest Porsche Boxster . This additional layer should not only reduce heat loss, but also the noise level in the vehicle by 50%.
