JVP aims to design and provide resins that meet customer needs by combining resin production technology that covers a wide range of degree of polymerization as well as a wide degree of hydrolysis with functional monomer copolymerization denaturation technology.
JMR is the general term for resins with a degree of polymerization and a degree of hydrolysis ranges that differ from that of general POVAL. They and are largely classified into an ultra low degree of polymerization resins and a low degree of hydrolysis resins.
An ultra low degree of polymerization is a degree of polymerization from 100 to 400 (the degree of polymerization of general POVAL is 400 to 4000).
A low degree of hydrolysis is a degree of hydrolysis from 0 to 80 mol% (the degree of hydrolysis of general POVAL is 80 mol% or higher). JMR has many interesting properties that differ from those of general POVAL.
- D Polymer
- A Series
- Other denatured POVAL
Denatured POVAL is the general name for POVAL that has functional groups other than hydroxyl and acetate groups of general POVAL. JVP has a commercialized D Polymer, which has carbonyl groups, and an A Series, which has carboxyl groups. Many other kinds of denatured POVAL are also available upon request.
Pharmaceutical grade POVAL
Pharmaceutical grade POVAL is polyvinyl alcohol (PVA) that can be used for pharmaceutical excipients.
The PVA is produced using our manufacturing control and quality control, which are compliant with the Internal- Initiative GMP standards guideline of the Japan Pharmaceutical Excipients Council (JPEC). The PVA is best suited for ingredients in cosmetics and pharmaceutical products.
Sodium-free POVAL contains a negligible amount of heavy metals. The principal metallic constituent, sodium (Na), is kept under 1 ppm.
