Following is the product of four or polyurethane applications Introduction:
First, a solvent resistance polyurethane elastomer Preparation
China's invention patents CN101130597A
This patent introduces a solvent resistance polyurethane elastomer of preparation, from polyester polyol with diisocyanate step by step or more of curing reaction. Polyester polyols by acid and polyol preparation, polyol can choose ethylene glycol, two glycol, butanediol, glycerol, Trimethylolpropane, propylene glycol and the new alcohol in a Group E Or several kinds. A flexible system of Jindao solvents (such as alcohol, toluene and xylene, acetone, cyclohexanone, butanone, etc.) for 48 hours, the growth rate of weight <70%. The elastomers can be used for printing and screen printing drum Blade films.
Second, a high water content of a new type of preparation and application of polyurethane
World Intellectual Property Organization, patent WO2008022798A1
The patent on a new polyurethane material, it has a high water content and flexibility of body or cell. Widespread use, its patent on the preparation process.
3, multi-isocyanate component and the preparation of Rigid Polyurethane Foam
