PROFESSIONAL PLASTICS, INC. The Nation’s Largest Supplier of High-Performance Engineering Materials High-Performance Plastic Materials Guide Polyimide Materials (PI) Vespel ® SP-1 Polyimide Vespel ® SP-1 polyimide offers a combination of temperature resistance, chemical resistance, mechanical toughness, natural lubricity, wear-resistance and insulation properties. This material provides operating temperatures from cryogenic to 300°C (570°F), great plasma resistance, plus a UL rating for minimal electrical and thermal conductivity. Vespel® SP-1 is the unfilled base resin grade. SP-1 provides maximum physical strength, elongation, and toughness as well as the best electrical and thermal insulation values. Vespel in manufactured in plates up to 10” x 10”. Meldin® 7001 Polyimide A thermosetting polyimide, Meldin® 7001 is made from the unfilled base resin. This grade offers the maximum mechanical properties and high chemical resistance. Meldin® 7001 is ideal for electrical and thermal insulating applications. More ductile than ceramics, and lighter weight than metals. This polyimide material is formed using high-pressure mold presses, automatic resin-feeding systems, and computer- controlled hydraulics. Meldin 7001 series features operational temperatures of up to 600ºF for continuous operation and 900ºF for intermittent exposure, and tight tolerances of ±0.001 in. Protomid® S1 Polyimide Shapes Protomid ® polyimide shapes provide superior high-temperature resistance, excellent wear and friction properties, good electrical and physical properties, and chemical inertness. Protomid® polyimide delivers outstanding resistance to creep and lubricated or unlubricated performance, ultra-low outgassing, excellent mechanical strength and impact resistance. Protomid® offers superior tensile strength and flexural modulus of temperature, and due to its outstanding creep resistance at high temperature, applied where very
