Description
VESPEL Resin is a high performance polymer mostly used in aerospace, semiconductor and transportation technology. Combining heat resistance, lubricity, dimensional stability, chemical resistance and creep resistance, it works well in hostile and extreme environmental conditions.
Unlike most plastics, VESPEL Resin does not produce significant outgassing (even at high temperatures) which makes it useful for lightweight heat shields and crucible support. It also performs well in vacuum applications and extremely low cryogenic temperatures. However, VESPEL does absorb a small amount of water, which results in a longer pump time while placed in a vacuum.
Although there are polymers that surpass individual properties of this polyimide, the combination of these factors is VESPEL’s primary advantage.
