VEHICLE WIPER BLADE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18158633 titled 'VEHICLE WIPER BLADE
Simplified Explanation
The abstract describes a patent application for a vehicle wiper blade made of polyurethane. The polyurethane used in the blade contains specific reactants and has specific molecular properties when ionized with a mass spectrometer. The concentration of a polyfunctional alcohol in the polyurethane is also specified.
- The vehicle wiper blade is made of polyurethane.
- The polyurethane contains specific reactants, including an isocyanate compound and an alcohol.
- The isocyanate compound includes diisocyanate and tri- or higher functional polyfunctional isocyanate.
- The alcohol includes tri- or higher functional polyfunctional alcohol.
- The diisocyanate has an aromatic ring in its molecule.
- The molecular properties of the polyurethane, when ionized with a mass spectrometer, are specified as M1, M2, and M3.
- The ratios of M2/M1, M3/M1, and M2/M3 fall within specific ranges.
- The concentration of the polyfunctional alcohol in the polyurethane is specified as 0.12 mmol/g to 0.65 mmol/g.
Potential applications of this technology:
- Manufacturing of vehicle wiper blades

Original Abstract Submitted
A vehicle wiper blade comprises a blade support part and a lip part coupled swingably with the blade support part via a neck. The lip part comprises polyurethane. The polyurethane comprises a reactant of a composition including an isocyanate compound which includes diisocyanate and tri- or higher functional polyfunctional isocyanate, and an alcohol which includes tri- or higher functional polyfunctional alcohol. The diisocyanate has an aromatic ring in a molecule. When a molecule of the polyurethane is ionized with a mass spectrometer of a direct sample injection system, then obtained M1, M2 and M3 satisfy the following relation: M2/M1 is 0.001 to 0.028, M3/M1 is 0.020 to 0.110, and M2/M3 is 0.013 to 0.300, and a concentration of the polyfunctional alcohol in the polyurethane is 0.12 mmol/g to 0.65 mmol/g.
