Description

Poly(2-Hydroxypropyl Methacrylate) is a synthetic polymer derived from the monomer 2-hydroxypropyl methacrylate, known for its excellent biocompatibility and film-forming properties. This polymer is a critical component in advanced material science, offering a unique combination of hydrophilicity, chemical resistance, and the ability to be functionalized. It is essential for formulators and manufacturers in the pharmaceutical, biomedical, and personal care industries who require a versatile, high-performance polymer for controlled-release systems, contact lenses, and specialty coatings.

Application

• Biomedical Devices: A key material for manufacturing soft contact lenses, intraocular lenses, and other implantable medical devices due to its high oxygen permeability and biocompatibility.
• Drug Delivery Systems: Used in the formulation of hydrogels and micro/nanoparticles for controlled and sustained release of active pharmaceutical ingredients (APIs).
• Personal Care & Cosmetics: Serves as a film-forming agent, thickener, and stabilizer in nail polishes, hair sprays, and skin care formulations.
• Adhesives & Sealants: Imparts flexibility, adhesion, and water resistance in pressure-sensitive adhesives and specialty sealants.
• Coatings & Inks: Utilized as a binder or additive in water-based coatings, printing inks, and overprint varnishes to enhance gloss, durability, and chemical resistance.
• Chromatography Media: Acts as a base matrix or functional layer for high-performance liquid chromatography (HPLC) columns and solid-phase extraction.
