Polyvinyl Alcohol (PVA) FAQ & Professional Terminology - FAQ
Q1: What is the main raw material of Polyvinyl Alcohol (PVA) and why is it significant?
PVA is synthesized by the hydrolysis of polyvinyl acetate, which is derived from vinyl acetate monomers. This ensures strong chemical resistance and environmental compatibility for a wide range of industries.
Q2: What does "degree of hydrolysis" mean in PVA?
The degree of hydrolysis quantifies the portion of acetate groups converted to hydroxyl groups on the polymer chain. Higher hydrolysis yields better water resistance and increased crystallinity.
Q3: What is the tensile strength range of industrial-grade Polyvinyl Alcohol (PVA)?
Typically, 25–41 MPa as per ISO 527 tensile testing for film samples—the exact value depends on grade and hydrolysis level.
Q4: What international standards apply for PVA packaging and shipment?
Commonly ISO 9001 for quality, REACH for chemical safety, FDA for food/medical, and RoHS standards for electronics applications.
Q5: What are the typical viscosities of PVA in water-based solutions?
Viscosity usually ranges from 4.5–90 mPa·s (4% solution at 20°C), tailored by adjusting polymerization processes per application.
Q6: What is the usual delivery lead time for bulk PVA orders?
Most manufacturers provide delivery within 7–15 working days, with expedited options for urgent bulk orders.
