Altron™ PC 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 Altron™ PC machine grade polycarbonate stock shapes an excellent choice for electrical/electronic applications (See Figures 12 and 13). Its strength, impact resistance and transparency also make it an ideal material for certain transparent structural applications such as sight glasses and windows.
Altron™ PC machine grade polycarbonate is stress relieved making it ideal for close tolerance machined parts. Our stock shapes are produced from polycarbonate resins which meet the requirements of ASTM D 3935.
A food grade polycarbonate that is compliant with FDA and Canada AG regulations is available upon request. Please contact Mitsubishi Chemical Advanced Materials for size availability and minimum quantities. A glass fiber reinforced polycarbonate grade is available upon request.
Consider Sultron PSU! This material offers hot water and steam performance up to 300°F.
Altron™ 1000 PC 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.
