Polypropylene

Polypropylene has one of the best chemical resistance ratio.

Under dry, non-abrasive aggressive conditions is polypropylene the excellent fiber. 

It is a very low density fiber (0.91). Due to their chemical structure, the fibers don't hydrolyze,

ACIDS - EXCELLENT
ALKALIS – EXCELLENT
OXIDISING AGENTS - FAIR
HYDROLYSIS - EXCELLENT
SOLVENTS – GOOD

Sensitive to UV light - is used in the food, pharmaceutical, chemical industry.
