If a seal is held at a high
temperature for a period of time, the elastomer will deteriorate to some
extent. In particular, the compression set and volume will change. The
hardness of the elastomer changes in two stages. At first, the seal will
become softer. bearing oil seals Preferential.This can cause problems
because the elastomer may flow through the clearance gap. Second, if the
seal remains too hot, chemical changes will occur with the elastomer
and the it will become harder.mechanical seal.
Choosing the right material for a high temperature seal is very important . Viton? seals resist hardening and embrittlement for more than 10,000 hours in air up to 204°C, and they withstand surges up to 315°C. Also, with the thermal capability of Viton?, shaft sealsome users can increase operating temperatures to improve productivity or gain other production advantages.
Kalrez? is an even better choice for a high temperature seal. Even after long-term exposure to temperatures up to 316°C (600°F), Kalrez? retains its elasticity and recovery properties better than other elastomers.bearing oil seals Preferential.
Our engineers are always happy to talk to you about designing an o-ring or seal to resist heat. The more resistance to heat an elastomer is, the more the cost goes up. It is more cost effective to carefully choose the elastomer with the right temperature tolerance than to buy the very best elastomer that will withstand the most heat.bearing oil seals Preferential.
