Outstanding Impact Resistance

PC is the only engineering plastic that is transparent. It is a non-crystalline plastic with outstanding impact resistance and can be used under a broad range of temperatures. PC also has superior creep resistance, and because of its low water absorption, has excellent dimension stability. Its electrical properties are also extremely good, but because of its low resistance to chemicals and propensity for stress cracks, care must be exercised.

Uses

• Optics-related components
• Electric/electronic devices components
• Medical devices components
• Food devices components

Characteristics

• PC (NC)-I has superior transparency.
• PC has superior impact resistance, as well as excellent heat and cold resistance.
• PC (BK) is a light-proof grade.

Grade List

Grade	Characteristics
