MACHINE GRADE polycarbonate (PC) is a transparent amorphous thermoplastic which offers very high impact strength and high modulus of elasticity. The material has a 290°F (145°C) heat deflection temperature at 264 psi, absorbs very little moisture and resists acidic solutions. These properties, in addition to good electrical characteristics, make MACHINE GRADE polycarbonate stock shapes an excellent choice for electrical/electronic applications. Its strength, impact resistance and transparency also make it an ideal material for certain transparent structural applications such as sight glasses and windows.
MACHINE GRADE polycarbonate is stress relieved making it ideal for close tolerance machined parts. Quadrant stock shapes are produced from polycarbonate resins which meet the requirements of ASTM D 3935.
A food grade polycarbonate that is compliant with FDA, NSF, Canada AG and USP Class VI regulations is available upon request. Please contact Cope Plastics for size availability and minimum quantities. A glass fiber reinforced polycarbonate grade is available upon request.
MACHINE GRADE polycarbonate is machine grade, not optically clear. It can be both mechanically and vapor polished to improve optical clarity. Caution: During machining, never use coolants with an aromatic base.
