Introduction

GreenPVA®  Polyvinyl Alcohol  PVA 


CAS No9002-89-5

Molecular formula[C2H4O]n

Product Description:

The various types of polyvinyl alcohol (PVA) are generated by alcoholysis reaction of polyvinyl acetate that is polymerized from vinyl acetate. Its polymerization degree is between 85% to 99.9% in the shape of flake, granular and powder, PVA of more than 99.5% alcoholysis degree can be dissolved in hot water of 95℃ , 88% can be dissolved in normal temperature water. Aqueous PVA has good spinnability, film-forming properties, bindablility and emulsibility. It is mainly used for producing synthetic fibre, PVA film, plastic, bonding agent and also for textile sizing, paper-making, process leather, building, dispersion agent for making PVC etc.

Notes:1. ◎: general use  2. ☆:Use under the situation  3. ●: powder more suitable


Usage:

Polyvinyl alcohol (PVA) can be widely used dry powder, powder putty, dry-mixed mortar, oilfield auxiliary chemical, in powder building materials, caking agent&bond of plastering anhydrite. Especially suitable to be used as interior & exterior wall putty and construction mortar, the main function is bonding, improving the flexility, water-retaining property, reducing friction, enhancing the work efficiency and quality(to prevent the crack &fall off from the floated coat, add adhesive strength and smooth texture).


Packing: in 25kgs paper/PP bag with or without pallets. Or in

500kgs/800kgs/1000kgs big bag on pallets.
