polymer processing

Not just about Eastman Chemical Company products but the trade name is perfect for properties of copolyesters. There is one more which I know SK Chemicals (in Poland known from PET installation) and maybe someone else but sorry if I skip it. Some information from chemistry. Amorphous transparent copolyester is produced by the reaction of terephthalic acid (TPA) with ethylene glycol (EG) which a certain amount of EG is replaced with cycloheksane dimethanol (CHDM). The most important factor is the proportion between EG and CHDM. When we increase the CHDM level we prevent crystallization, increase chemical resistant, transparency, and improve processability (lower melt temp., less restricted drying). For the reason I am involved in polymer field I promote even I do not know about it polymers. The key point is to replace glass, on the other hand to replace polymers such as: PMMA, SAN, etc. in the packaging segment. These materials have some adventures comparing to copolyesters, primo the
