Properties and applications


This page give info on how to select a tubing for your special application:
Types, useful temperature range, chemical resistance, properties and characteristics to look for.

LEGEND:

A No damage after 30 days of constant exposure.
B Little or no damage after 30 days of constant exposure.
CSome effect after 7 days of constant exposure . Effects may include: cracking crazing , loss of strength, discoloration, softening, or swelling. Effects are normally reversible.
DNot recommended for contionous use. Immediate damage may occur.
