Webbegun to melt. Since the T g only occurs in amorphous material, in a 100% crystalline material there would not be a T g. Continued heating drives the material through the T α * and T ll. The former occurs in crys-talline or semi-crystalline polymer and is a slippage of the crystallites past each other. The latter is a move-ment of coordinated ... Web11 sep. 2024 · US firm Plastic2Oil works to turn waste plastic into sulphur fuel, using the discarded material as feedstock to create an ‘ultra-low sulphur diesel’ that contains 15ppm or lower sulphur content. Currently, ultra-low sulphur diesel is primarily produced from petroleum, though Plastic2Oil provides a viable alternative with its plastic-derived ...
