商品

Chitin, a natural polysaccharide, is the second most abundant natural biopolymer in the world, after cellulose.

Carcinogenic compounds in elastomers: 1,3-butadiene and isoprene used in elastomer manufacturing, classified as carcinogenic by IARC.

Polymers, natural or synthetic, are vital in medical advancements, contributing to device and pharmaceutical development in therapy.

Chitosan is a naturally occurring polysaccharide ideally suited for use in medical supplies, devices, therapeutics, and diagnostics. The unique natural characteristics of chitosan include its cationic, biocompatible, biodegradable, non-toxic, non-immunogenic, and antimicrobial properties.
