Description

PVP VA64 (Polyvinylpyrrolidone/Vinyl Acetate Copolymer) is a high-performance functional polymer widely used in pharmaceutical formulations, nutraceuticals, cosmetics, coatings, and specialty industrial systems.

For global buyers, choosing a PVP/VA supplier is not only about product specifications — it is about regulatory compliance, production stability, supply security, and long-term cost control.

East Chemical focuses on providing pharmaceutical and industrial customers with compliant, traceable, and commercially reliable VA64 solutions that help reduce sourcing risks while improving formulation efficiency and manufacturing performance.

Specification

Key Application Fields

1. Solid Dosage Forms and Granulation Processes

VA64 is a superior binder for direct compression processes, preventing tablet top cracking and delamination, significantly improving the yield rate in high-speed tablet production.

2. Film Coating Protection

It can form a flexible, moisture-proof, and oxygen-barrier protective film, suitable for protecting sensitive active pharmaceutical ingredients, masking unpleasant drug odors, and not delaying drug release.

3. Innovative Drug Delivery (3D Printing, Oral Films)

Precise molecular weight control (45,000 - 70,000) makes it suitable for hot melt extrusion technology and 3D printing of pharmaceutical tablets, making it an optimal raw material.

Key Commercial Advantages

Solubility improvement can exceed 85%

Bioavailability enhancement up to 30%+

Faster dissolution and disintegration performance

Improved powder uniformity and granulation stability

Better compatibility with APIs and excipients

Reduced formulation adjustment frequency

With a glass transition temperature (Tg) of approximately 105°C, the material also maintains excellent thermal stability during industrial processing and long-term storage, helping manufacturers reduce caking risks and production instability.

Why Buyers Choose Our PVP VA64

Regulatory Compliance & Quality Assurance

For pharmaceutical and regulated industries, compliance and batch consistency directly affect product registration, formulation approval, and export operations.

Our PVP VA64 is produced under strict quality control standards and supports international compliance requirements including USP / EP / JP specifications, FDA DMF support, and REACH-related documentation. Heavy metal residues are controlled below 5 ppm, while residual solvents and impurity profiles are monitored according to pharmaceutical-grade requirements.

To ensure stable industrial use, every batch undergoes comprehensive testing including:

Molecular weight distribution

Viscosity stability

Moisture content

Residual monomer control

Solubility verification

Appearance and purity inspection

Complete COA, TDS, and MSDS documentation is available to support customer audits, import registration, and long-term procurement compliance.

Packaging

Each batch undergoes key parameter testing before shipment to ensure stable core quality indicators of

All products undergo rigorous testing before leaving the factory, and each batch comes with a standard analysis certificate, a chemical safety data sheet, and technical data sheets.

Standard packaging: 25 kg fiber drum with an inner moisture-proof liner; cold chain logistics services are available for temperature-sensitive areas.
