Overview
Modified polyvinyl alcohol (PVOH) is graded according to different degrees of polymerization, hydrolysis and copolymerization monomers.
The modification of PVA is mainly to use the double bonds, ester groups and the chemical activity of the hydroxyl group after alcoholization of vinyl acetate to change the side chain group or structure, and introduce other monomers to become copolymers dominated by PVA.
General properties
The PVOH 8825RF is an anionic modified polyvinyl alcohol (PVOH) specifically formulated for the production of specialized grades of PVA films. The mechanical strength of PVA films derived from this particular PVOH variant increases proportionally with higher levels of polymerization or alcoholization.
Applications
8825RF is specifically designed to manufacture biodegradable PVA films.
8825RF can be compounded with conventional PVOH to reduce costs.
8825RF can also be used in combination with 728F to improve the overall performance of PVA films.
Package
Packed in 25 kg paper bags。
Storage
PVOH 8825RF should be stored in a ventilated and dry warehouse, away from direct sunlight and water. It should also be kept away from moisture and fire. The product must be used within 12 months of delivery, but if it is stored for more than 12 months, it is recommended to test before use.
