Para Aramide p-AR

Although para-aramids are high in strength, there is some problem with chemical resistance. Homopolymer para-aramids have relatively weak resistance to strong acids and bases. Kevlar and Twaron, for instance, cannot be bleached with chlorine and are often not approved for food handling in protective gloves. The fine surface structure of Technora copolymer allows it to have much higher chemical resistance. Kevlar has new forms with increased strength and improved properties.

Co-polymer para-aramids have advantages with increased abrasion resistance and steam resistance - useful properties in many protective applications.

Typical properties of para-aramids are as follows:
