    1. What is the Urethane Elastomer?
    (1) Definition :
    Polyurethane elastomer is flexible, and posse's elasticity nature likes rubber. The following is molecular structure.
    (2) Polyurethane characteristics :
    It is good for :
    1. Abrasion resistance
    2. Elasticity no matter with high or low hardness
    3. Tensile strength, tear strength, compression strength
    4. Chemical, oil ozone and cold resistance
    5. Impact resistance
    6. Absorption of vibration
    7. Workability and so on

    This is Cross linking and good curing agent for PU elasticity. The finished products as following:
    1. Caster: PU Caster and Wheels
    2. Seals: PU Hydraulic Seals and Packages
    3. Spring: PU Rod , Sheet , Bar and Film
    4. Blade: PU Drum Blade for Copier and Laser Printer
    5. Roller: All Kinds of PU Rollers
    6. Parts: PU Flexible Coupling and Parts

    Also we can recommend and introduce the supply of prepolymer and finished products for your asking only.
