Description

Poly(epichlorohydrin)

Poly(epichlorohydrin) is a high-performance, elastomeric polymer used in pharmaceutical, biomedical, and industrial applications for its chemical resistance, gas impermeability, and thermal flexibility. Synthesized by the polymerization of Epichlorohydrin, this homopolymer or copolymer is valued for its flexibility, oxidative stability, and compatibility with a wide range of formulation systems. Poly(epichlorohydrin)

• Is a Chlorine-containing polyether with excellent resistance to fuels, oils, and oxygen
• Is used in elastomeric pharmaceutical closures, seals, medical tubing, and barrier layers
• Exhibits good low-temperature performance and long-term aging stability
• Is suitable for compounding, injection molding, extrusion, and film applications
• Is manufactured under Good Manufacturing Practice (GMP) certified conditions
• Is supplied with complete regulatory documentation including Certificate of Analysis (CoA) and technical data

Poly(epichlorohydrin) is available as both a homopolymer and copolymer (e.g., with ethylene oxide or allyl glycidyl ether), offering tunable hardness, flexibility, and cure profile. The polymer backbone consists of repeating epichlorohydrin units, which impart polarity and enhanced compatibility with pharmaceutical and medical-grade materials.

In health-related and pharmaceutical applications, Poly(epichlorohydrin) is used in:

• Pharmaceutical stoppers and closures requiring high gas barrier properties
• Medical device components, including tubing, gaskets, and diaphragms
• Controlled release drug delivery matrices and depot systems
• Adhesives and coatings for use in clinical packaging or inhalation devices
• Laboratory and diagnostic tubing or seals exposed to reactive chemicals

Poly(epichlorohydrin) is particularly useful in applications where chemical exposure and gas permeability must be minimized. It exhibits high elasticity at low temperatures and maintains its mechanical integrity under oxidative stress and long-term aging.

CarboMer supplies Poly(epichlorohydrin) in various molecular weights, cure systems, and processable forms, including solid rubber, liquid prepolymer, and masterbatch formats. Custom formulations are available based on customer specifications.

The material is packaged in sealed, contamination-controlled containers to preserve physical and chemical properties. Available in R&D, pilot, and commercial-scale volumes. Minimum order quantities (MOQ), lead times, and documentation, including CoA and SDS are available upon request.

Each batch is tested for identity (NMR, FTIR), molecular weight (GPC), chlorine content, residual monomers, thermal stability (TGA), and mechanical properties. All shipments are accompanied by Certificates of Analysis (CoA), Safety Data Sheets (SDS), and full traceability documentation.

As with all CarboMer functional polymers and elastomers, Poly(epichlorohydrin) is supported by formulation expertise, regulatory support, and secure global logistics to meet the needs of demanding pharmaceutical and medical applications.
