What is the effect of humidity in the changing nylon film dimension?

Nylon film moisture absorption principle Nylon film moisture absorption principle: BOPA film is made of Polyamide 6(Nylon 6) as raw material. Polyamides contain polar amide groups (- CO-NH-), in which one -NH-group energy and one -C. The formation of hydrogen bonds is one of the important factors for the high crystallinity of polyamide. Although nylon […]
