| 15503, 5506, 5592 and 5595 are also available with a polyester (PET) film on one side to provide a non-tacky surface. Product numbers are 5503S, 5506S, 5591S, 5592S and 5595S. 2 Only “S” version is available in 0.5 mm thickness. 3 “S” designation signifies a polyester film on one side to provide a non-tacky surface. “H” designation signifies a product with one non-tacky surface without the use of a PET film. |
4 5591S and 5592S have similar bulk thermal conductivity, but the 5591S has ultra-soft firmness. The 5592S is considered to have soft firmness. 5 5591S, 5592S and 5595S versions tested. |
