PVA
Describe:
Hot water soluable polyvinyl alcohol PVA 0588/ 0888/ 2899/ 1799/ 1788/ 2499/ 2488 for film making
Polyvinyl alcohol PVA divided into 99 series and 88 series according to the difference of polymerization and alcoholysis degree.
The dry mortar chemical additives PVA developed by us is PVA1799-2499 series and PVA1788-2488 series hybrid products, appearance in granular and powdered mixture. It combined the advantages of the series 99 and 88, overcome original disadvantage , increased the bond strength and thermal stability, accelerated dissolution in lower temperature. It greatly reduced the production cost, it as the bonding material widely used in construction, ceramics, wood, textile, etc.
