| CALIBRE 303 10 TNT | ||
| Dow Plastics - Calibre 303 10 TNT Polycarbonate | ||
| Polycarbonate is one of the toughest, most dimensionally stable thermoplastics over a wide temperature range. Polycarbonate has exceptionally high impact strength. Polycarbonate is unaffected by water below 140°F and can be used in boiling water on a limited basis. Polycarbonate is unaffected by greases, oils detergents, aliphatic hydrocarbons, most mineral acids, and the higher alcohols. It is attacked by chlorinated hydrocarbons, and most aromatic solvents, esters, and ketones. Polycarbonate has a blue tinted transparency with a 89% light transmission. | ||
| APPLICATIONS | ||
| Fasteners - Washers - Spacers - Lenses - Housings. | ||
| PRODUCT DESCRIPTION | ||
| CALIBRE 300 series resins are general purpose, UL listed polycarbonate resins. CALIBRE 300 series resins exhibit an excellent physical property balance of heat resistance, and impact strength. | ||
