What is Vespel SP 1?
DuPont™ Vespel® SP-1 is an unfilled Polyimide offering superior wear and insulation properties with operating temperatures from cryogenic to 260°C (500°F). Vespel® SP-1 has low electrical conductivity and the highest elongation and purity of the SP family.
Is vespel a peek?
Vespel® offers low friction and superior wear performance. While PEEK offers good all-around friction and wear resistance, Vespel® provides a low wear rate and a low, constant CF. Vespel® parts can even run dry if lubrication fails, making them a common choice for bearings and other high-wear applications.
Is vespel machinable?
VESPEL® shapes are relatively easy to machine because of their inherent mechanical strength, stiffness and dimensional stability at machining temperatures. In addition, they can be machined with stan- dard metalworking equipment to produce parts to tolerances once considered too close for plastic materials.
Who makes vespel?
DUPONT PRODUCTS
DUPONT PRODUCTS & SERVICES Vespel® S products are highly durable polyimides used in demanding applications where exceptional thermal resistance (cryogenic to 349°C), low wear and/or low friction, strength and impact resistance are desired as custom parts or stock shapes.
Where is vespel used?
Vespel is mostly used in aerospace, semiconductor, and transportation technology. It combines heat resistance, lubricity, dimensional stability, chemical resistance, and creep resistance, and can be used in hostile and extreme environmental conditions.
How do you clean vespel?
Burrs can be removed using the same methods used on metal parts. DuPont™ Vespel® parts may also be tumbled in vibratory or rotating deburring equipment, along with abrasive media, tumbling detergent and water. Thin walls or pointed surfaces with angles less than 90° may experience chipping if tumbled.
What is DuPont Vespel?
DuPont™ Vespel® Polyimide is an extremely high temperature, creep resistant plastic material that is often used in high heat environments where thermoplastic materials lose their mechanical properties.
What is a Vespel insert?
Vespel® S products are highly durable polyimides used in demanding applications where exceptional thermal resistance (cryogenic to 349°C), low wear and/or low friction, strength and impact resistance are desired as custom parts or stock shapes.
What is the Vespel® SP-1?
Vespel® SP-1 has low electrical conductivity and the highest elongation and purity of the SP family. Available as stock shapes. For Vespel® SP-1 chemical resistance view our chart. Semiconductor manufacturers often find components fabricated from Vespel® SP-1 shapes useful in production processes.
What is the class of a Vespel?
Vespel® SP-1 is specified as Class 1 per AMS 3644G. Length, width, thickness, and diameter tolerances vary by size, by manufacturer, brand, and grade.
What is the tensile strength of DuPont Vespel?
Typical Properties OF DuPont™ Vespel® SP-1 Polyimide ASTM Method Units SP-1 Unfilled Tensile strength 23°C (73°F) D1708 / D638 MPa (kpsi) 86.2 (12.5) Tensile strength 260°C (500°F) D1708 / D638 MPa (kpsi) 41.4 (6.0) Elongation at break 23°C (73°F) D1708 / D638 % 7.5
Why choose DuPont™ Vespel® seals?
The inherent resistance of DuPont™ Vespel® to stress relaxation allows it to maintain much of its apparent modulus over extended periods of time, resulting in long-term sealing performance. Want to lean more? Download DuPont™ Vespel® for Valve Seats and Seals white paper.
