    Hydrosize® HP-1632
    High Temperature Sizing Solutio    n

    Description: Hydrosize® HP-1632 is a high temperature aqueous polyimide sizing that is essentially solvent-free and HAPS free. HP-1632 has excellent thermal and thermo-oxidative stability with the onset of degradation approaching 500°C (932°F) and a glass transition temperature (Tg) greater than 245°C. HP-1632 has excellent adhesion properties and is abrasion resistant.

    Hydrosize® HP-1632 was designed to withstand the compounding conditions and form strong interfacial bonding with PEEK, polyimides, high temperature polyamides and other high performance resins. The sizing (and thus the interface) will remain stable during extended high temperature continuous use conditions.

    Technical Support: Hydrosize® Technologies, Inc. scientists have extensive knowledge and practical experience with binders and sizings, their application to fibers, and their influence on composite properties. Please do not hesitate to request our assistance. The test methods used to determine the reported properties are available upon request.

    Storage: To ensure maximum stability and properties this dispersion should be stored between 5°C (4 1°F) and 35°C (95 °F). Prevent freezing. The product should be stored indoors in tightly closed containers away from heat sources and sunlight. If frozen, warm to room temperature and mix well before using. All storage areas should conform to local fire and building codes. Hydrosize® HP-1632 should be stored away from all sources of flame or combustion.

    Standard Package: Non-returnable, lined fiberwall drums of 450 lbs. net weight.

    Safety: Read and understand the Material Safety Data Sheet before working with this product.
