Line 41: * '''Bottom layer:'''..Glass Within this last specification mentioned above, the 2 thermoplastic layers together with the LED Interlayer will reach a total thickness of about 2mm. The usually very economical PVB is the most used [[Laminated glass\|lamination interlayer]]. Its lamination is based on a nip roller pre-heating step followed by an autoclaving process with a final stage ideally below 125 °C and 14 athmospheres. However, polyester has a better adhesion to [[Thermoplastics polyurethanes (TPU)\|TPU]], to [[Ethylene-vinyl acetate\|EVA]] or to EVASafe[[http://www.bridgestone.com/products/diversified/evasafe/index.html\| EVASAfe]], which are often laminated using simple vacuum tables. EVASafe contain some hygroscopic crosslinking agent, which will allow its partial crosslinking to active sites of the substrates. TPU may be used up to 125 °C. EVASafe should be used below 110 °C. ==References==
