The price for virgin material is around $8.50 per kg, falling to $2.50 for recycled material. PET (polyethylene terephthalate) is also a low-price material manufactured in huge quantities. A spectrum of quality is available. WebThe molecular weight of polyethylene terephthalate (PET) is usually described in terms of intrinsic viscosity. This is the IV value in dl/g. The longer the polymer chains, the higher this characteristic value. This makes it possible to demonstrate molecular chains and how they can occur when moisture that is too high during the melting process. الاسره نكره ام معرفه
