High Purity Bisphenol A Propoxylate CAS 62617-47-4 Reactive Polyether Raw Material for Polyurethane Elastomer & Waterproof Coating

Detailed Product Description

Bisphenol A Polyoxypropylene Ether (Propoxylated Bisphenol A, CAS 62617-47-4) belongs to reactive propoxylated polyether. It is produced via ring-opening polymerization of bisphenol A and propylene oxide without solvent addition. Different molecular weight grades are available to match different formulation demands.

Different from ordinary surfactants, it participates in crosslinking reaction during resin curing rather than simple physical blending. It effectively enhance elongation at break, impact resistance and anti-hydrolysis performance of finished products. Widely adopted in high-end polyurethane systems, anti-corrosion coatings and structural adhesives. Strict filtration process ensures clear appearance and stable quality for industrial continuous production and export orders.

Applications

1. Polyurethane Industry

   Used for PU elastomer, PU waterproof coating, PU sealant and casting PU resin. Improve tensile property, low-temperature flexibility and hydrolysis resistance.

2. Epoxy & Composite Materials

   Modifying epoxy resin and unsaturated polyester, boost toughness, decrease internal stress, apply for anti-corrosion resin and FRP products.

3. Coating & Adhesive

   Serve as toughening intermediate for solvent-free coating, structural adhesive and potting glue. Optimize adhesion to metal and plastic substrates.

4. Electronic Fine Chemicals

   Applied in electronic encapsulant, insulating potting material for better thermal stability and mechanical property.
