Description

Poly(vinyl butyral)

Poly(vinyl butyral) is a versatile, high-performance polymer used in pharmaceutical, industrial, and medical applications for its adhesive, film-forming, and optical properties. As a copolymer of Vinyl alcohol and Butyraldehyde, Poly(vinyl butyral) exhibits excellent solubility in organic solvents and is widely used in coatings, drug delivery systems, and medical device manufacturing. Poly(vinyl butyral)

• Is a non-ionic, thermoplastic polymer with strong adhesive and film-forming properties
• Is used in pharmaceutical coatings, controlled-release systems, and medical device applications
• Exhibits excellent flexibility, chemical resistance, and moisture resistance
• Is ideal for use in coatings, films, and adhesives where clarity and stability are important
• Is manufactured under Good Manufacturing Practice (GMP) certified conditions
• Is supplied with complete regulatory documentation including Certificate of Analysis (CoA) and technical data

Poly(vinyl butyral) (PVB) is produced through the reaction of Poly(vinyl alcohol) with Butyraldehyde under acidic conditions. The resulting polymer can be customized by adjusting the degree of Butyral substitution level and molecular weight to achieve the desired balance of flexibility, strength, and solubility.

In pharmaceutical and medical applications, Poly(vinyl butyral) is used in:

• Film coatings for tablets and capsules to control drug release or provide protection against moisture
• Controlled-release oral dosage forms where a consistent and prolonged release is required
• Ophthalmic solutions for sustained delivery of eye medications
• Adhesives and coatings in medical devices requiring flexibility, clarity, and biocompatibility
• Drug-eluting coatings for medical implants and stents

The polymer’s ability to form clear, tough films with high mechanical strength and adhesion properties makes it an ideal candidate for use in protective coatings, encapsulation systems, and as a binder in various drug delivery platforms.

CarboMer supplies Poly(vinyl butyral) in different molecular weights and degrees of substitution, enabling customization for specific formulation needs, including film coating systems, tablets, or controlled-release formulations.

The material is packaged in sealed, tamper-evident, moisture-resistant containers. Available in R&D, pilot, and commercial-scale volumes. Minimum order quantities (MOQ), lead times, and documentation including CoA and SDS are provided upon request.

Each batch is tested for identity (NMR, FTIR), molecular weight, butyral content, viscosity, loss on drying, and microbial purity. All shipments include Certificates of Analysis (CoA), Safety Data Sheets (SDS), and full traceability documentation.

As with all CarboMer functional polymers and excipients, Poly(vinyl butyral) is supported by formulation expertise, regulatory compliance, and global sourcing to ensure success in a wide range of drug delivery and medical applications.
