Vespel® vs Meldin® Test Blanks - suitable for material qualification and testing purposes. Vespel® SP Polyimide Rods & Plates are high-performance polyimide shapes offer a broad combination of temperature resistance, chemical resistance, mechanical toughness, natural lubricity,wear-resistance and insulation properties. DuPont Vespel SP-1 parts provide operating temperatures from cryogenic to 300°C (570°F), great plasma resistance, plus a UL rating for minimal electrical and thermal conductivity.
Vespel ® is a registered trade name of Ei DuPont DeNemours.
Meldin® 7000 Series Polyimide Rods & Plates offer superior mechanical properties & high chemical resistance. Meldin® is ideal for electrical and thermal insulating applications. More ductile than ceramics, and lighter weight than metals, Meldin® is a popular choice for structural parts in aerospace and other applications where metal replacement is desirable. Operates from Cryogenic to 315°C (600°F) & Intermittently to 482°C (900°F)
Meldin ® is a registered trade name of Saint Gobain Performance Products.
FEATURES AND BENEFITS
Meldin® 7000 series polyimide shapes offer a new option for material design engineers who require the superior performance of an isostatic or compression-molded polyimide shape, without the extreme costs associated with Vespel®.
Most customers have realized significant costs savings by testing and qualifying Meldin into applications that previously had been limited to Vespel. Meldin provides high performance combined with a more economical cost basis.
