NEW DUPONT VESPEL PARTS AND SHAPES FOR THE SEMICONDUCTOR INDUSTRY
DuPont Vespel announces the introduction of TP-8005, a new family of finished parts and shapes made of translucent, unfilled thermoplastic polyimide. Their high purity and resistance to plasma and heat makes TP-8005 well suited for uses within the semiconductor industry. The material is weldable and wear resistant and maintains its good dielectric properties even at permanent operating temperatures of up to 200 °C. As it is thermo-formable, TP-8005 offers finished parts and shapes with geometric flexibility and the opportunity to creatively improve the function and cost of mechanical design. The high elasticity of the material, tensile elongation at break of 79 per cent, makes the parts easy to install, even in the tightest of locations. When applied, Vespel TP-8005 can provide semiconductor equipment parts that are exceptionally pure and withstand deformation from acid bath used to rinse the semiconductor. It is therefore an advantageous alternative to less durable metal and ceramic components commonly used in such aggressive environments. Examples of the Vespel TP Family are: • Vespel TP-8005 - offers translucent polyimide parts designed specifically for semiconductor and high-purity applications. • Vespel TP-2875 - ideal for petrol and diesel fuel-pump parts, thrust washers, and other applications in lubricated environments. • Vespel TP-2346 - offers great wear resistance and is used in transmission shift pads, ATV thrust washers, and clutch buttons. • Vespel TP-1012BK - provides high-modulus parts with superior wear resistance in dry environments. Used widely in the automotive, aerospace and semiconductor industries, DuPont Vespel parts and shapes consists of five families of materials that provide a unique combination of the physical properties of plastics, metals and ceramics, while offering maximum design flexibility. Starting as the Vespel S line, the family has expanded significantly to include the introduction of Vespel TP, a new thermoplastic material developed by DuPont, and the addition of three other material families: Vespel CP (composites), Vespel chemical resistant and Vespel assemblies.
