USAGE

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 : Abrasion resistance Elasticity no matter with high or low hardness Tensile strength, tear strength, compression strength Chemical, oil ozone and cold resistance Impact resistance Absorption of vibration Workability and so on
	This is Cross linking and goof 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. Squeegees: PU Squeegees for Screen Printing 6. Friction Wheels: PU Disc and Friction Wheel for Textile Machine 7. Roller: All Kinds of RU Rollers 8. Parts: PU Flexible Coupling and Parts Also we can recommend and introduce the supply of prepolymer and finished products for your asking only.
