Altron™ 1000 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™ 1000 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™ 1000 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 Mitsubishi Chemical Advanced Materials PSU! This material offers hot water and steam performance up to 300°F.
Altron™ LSG PC stock shapes are produced from selected batches of a specific non-UV-stabilized polycarbonate resin. This polymer shows a combination of good mechanical, thermal and electrical properties combined with a good chemical resistance. The composition of the resin used for the production of the Altron™ LSG PC stock shapes complies with the regulations that apply in the Member States of the European Union (Directive 2002/72/EC, as amended) and in the United States of America (FDA) for plastic materials and articles intended to come into contact with foodstuffs. Altron™ LSG PC stock shapes have also been successfully type tested for their compliance with both United States Pharmacopeia (USP) and ISO 10993-1 guideline requirements for Biocompatibility Testing of Materials, and they come with full traceability from resin to stock shape. These features, added to a good sterilizability by means of ethylene oxide, plasma and gamma irradiation, make Altron™ LSG PC stock shapes suitable for applications in the medical, pharmaceutical and biotechnology markets.
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.
