The U.S. Army was primarily interested in a synthetic insulation that would be comparable to goose down in weight, compressibility, and warmth, but also retain heat while in the presence of moisture. In 1985, United States Patent 4,588,635 for "synthetic down" was filed and ultimately approved in May 1986. This original non-woven insulation ...
Polyester fiber is used as cushioning and insulating material in pillows, comforters, stuffed animals and characters, and upholstery padding. Polyester fabrics are highly stain-resistant since polyester is a hydrophobic material, making it hard to absorb liquids.

Urea-formaldehyde insulation Urea-formaldehyde foam insulation (UFFI) commercialisation dates to the 1930s as a synthetic insulation with thermal conductivity of 0.0343 to 0.0373 W/m⋅K, [ 13 ] equating to U values for 50 mm thickness of between 0.686 W/m 2 K and 0.746 W/m 2 K or R-values between 1.46 m 2 K/W and 1.34 m 2 K/W (0.26 °F⋅ft 2 ...

Thinsulate is a brand of synthetic fiber thermal insulation used in winter clothing. The word is a portmanteau of the words thin and insulate , trademarked by 3M. [ 1 ] The material is made by the 3M Corporation and was first sold in 1979. [ 2 ]
This is a list of insulation materials used around the world. Typical R-values are given for various materials and structures as approximations based on the average of available figures and are sorted by lowest value. R-value at 1 m gives R-values normalised to a 1 metre (3 ft 3 in) thickness and sorts by median value of the range.
Insulation may be categorized by its composition (natural or synthetic materials), form (batts, blankets, loose-fill, spray foam, and panels), structural contribution (insulating concrete forms, structured panels, and straw bales), functional mode (conductive, radiative, convective), resistance to heat transfer, environmental impacts, and more.
