Description

Poly(Styrene-Co-Divinylbenzene) is a synthetic, cross-linked copolymer widely utilized as a robust, porous matrix for separation and purification processes. This material is essential for applications requiring high chemical stability and consistent particle morphology. It is a critical component for manufacturers and research facilities in the pharmaceutical, biotechnology, and water treatment industries.

Application

• Primary matrix for ion exchange resins used in water softening, demineralization, and ultrapure water production.
• Stationary phase support for chromatographic separation in High-Performance Liquid Chromatography (HPLC) and Size-Exclusion Chromatography (SEC).
• Solid support for peptide synthesis and other solid-phase organic synthesis (SPOS) applications.
• Base material for adsorbent resins in the removal of organic contaminants from process streams and wastewater.
• Catalyst support in various chemical manufacturing processes.
• Used in the formulation of specific polymer composites and specialty coatings.
