Polyester

Polyester is the most versatile, most cost-effective and most widely used filter media

It is strong, abrasion resistant can work up to 150°C and has good resistance to most acids, solvents and oxidizing agents.

ACIDS – GOOD
ALKALIS – FAIR
OXIDIZING AGENTS – GOOD
HYDROLYSIS – POOR
SOLVENTS – GOOD

Avoid strong alkali and acid environments at elevated temperatures – the most versatile of the low temperature fibers, used in the cement, metal processing, flour and wood industries.
