Discs are commonly made of multiple layers of poly carbonate. Therefore it would be safe to assume that Blu-Ray discs are made of the same materials.

yes, i m very much interested in the type of chemical composition that is used to produce the blu-ray dvd media. As we are looking forward to a new media to support, we do very much welcome input on this matter.

currently as we know, TFP is one of the main ingredient for DVD, so as for blu-ray, we are still finding the opportunity

do send mail to us at truchemic@gmail.com if you could kindly share us the info. or looking for forward business opportunity in the chemical supply line.

"A BD-ROM (prerecorded) is a sandwich of multiple layers of materials and either one or two data layers (single or dual-layer). A single-layer (SL) disc begins with the substrate (polycarbonate) molded with a spiral track of pits and lands extending from the inside to the outside diameter of the disc. Added to this substrate are a reflective layer (aluminum or silver alloy), a cover layer (polycarbonate film, silicone and others) and finally a transparent protective hard coating (silicon dioxide resin, silicone and others). To seal and prevent it from absorbing water, which might warp the disc, the substrate is also topped with a moisture barrier (silicon nitride and others).

The structure of a dual-layer (DL) disc is more complex. First comes the substrate with its track of pits and lands [data layer 0], a reflective layer (silver alloy), a spacer layer (pressure sensitive adhesive, photo curable acrylate adhesive and others) imprinted with a second track of pits and lands [data layer 1], a semi-reflective layer (silver alloy), a cover layer and then a protective hard coating."
