Product Description



Poly(vinyl alcohol)  ( PVOH PVA , or  PVAl ) is a  water - soluble   synthetic polymer . It has the idealized formula [CH 2 CH(OH)] n . It is used in  papermaking textile warp sizing , as a thickener and emulsion stabilizer in  PVAc  adhesive formulations, in a variety of coatings, and  3D printing . It is colourless (white) and odorless. It is commonly supplied as beads or as solutions in water.  Without an externally added crosslinking agent, PVA solution can be gelled through repeated freezing-thawing, yielding highly strong, ultrapure,  biocompatible   hydrogels  which have been used for a variety of applications such as  vascular stents cartilages contact lenses , etc..

 

Product Applications


PVA is used in a variety of medical applications because of its biocompatibility, low tendency for protein adhesion, and low toxicity. Specific uses include cartilage replacements, contact lenses, and eye drops.Polyvinyl alcohol is used as an aid in suspension polymerizations. Its largest application in China is its use as a protective colloid to make polyvinyl acetate dispersions. In Japan its major use is the production of Vinylon fiber.This fiber is also manufactured in North Korea for self-sufficiency reasons, because no oil is required to produce it. Another application is photographic film.

PVA-based polymers are used widely in additive manufacturing. For example, 3D printed oral dosage forms demonstrate great potential in the pharmaceutical industry. It is possible to create drug-loaded tablets with modified drug-release characteristics where PVA is used as a binder substance.

Medically, it may also used as the embolic agent in a Uterine Fibroid Embolectomy (UFE)
