DURASTAR® DS2010 (PCTG) (POLYCYCLOHEXYLENE DIMETHYLENE TEREPHTHALATE, ACID) | ||
DURASTAR® DS2010 (PCTG) | ||
Eastman Chemical Company - Polycyclohexylene Dimethylene Terephthalate, Acid | ||
Durastar® has an excellent appearance and is nearly water-clear. Its most outstanding features are toughness, dimensional stability and chemical resistance. Exposure to aromatic oils often causes crazing or actual fracture of many polymer resins, but DS2010 maintains its physical properties when exposed to these oils, and its appearance is virtually unchanged. Durastar® is nearly clear in its natural color. | ||
