Dupont Vespel SP-211 sheets/ vespel® 211 sheets

Dupont Vespel SP-211 sheets/ vespel® 211 sheets Descrition:

Polyimide (Pl) is a polymer containing imide structure in the main chain of molecular structure. Polyimide is a very large family, which can be divided into homobenzoic PI, soluble PI, Polyamide-imide (PAI) and polyetherimide (PEI) four categories, the main chain of high-performance PI is mostly aromatic ring and heterocyclic ring as the main structural unit. Polyimide is one of the organic polymer materials with excellent comprehensive properties, high temperature resistance of more than 400 ° C, long-term use temperature range -260~330 ° C, no obvious melting point, high insulation performance belongs to F to H class insulation materials. Mechanical properties, good fatigue resistance, good self-lubrication; Abrasion resistance, small friction coefficient and not affected by humidity and temperature, high impact strength, but sensitive to notch.

Common Dupont Vespel SP-211 sheets/ vespel® 211 sheets models:

Vespel® SP-1 tubes (tan): Basic specification with highest mechanical strength and electrical properties

Vespel sp-21 (black): with 15% graphite filling specification, provides abrasion characteristics and heat resistance,

Vespel SP211(black): Fill with 15% graphite and 10%PTFE. The lowest static friction coefficient is obtained. Suitable for use in medium temperature environment.

Vespel SP22(black) is filled with 40% graphite for the smallest expansion coefficient and highest creep resistance.

Vespel SP3(black): with 15% molybdenum disulfide filling specifications, suitable for friction sliding requirements in vacuum or inert gas.
