Choose such pu castor does not need any reason
Choose such pu castor does not need any reason, in a kind of spinning is held to ensure the stability of the draft, just have good resilience, and weak sex requirement tire smaller permanent opening of shape, under the same pressure of large diameter roller has good elasticity, and the curved contact surface of the roller, the friction boundary expansion, the floating area, strong control of floating fibers, is advantageous to the variable speed point jaw forward focus on comparison of vibration absorption, Laura groove can be reduced or dust miscellaneous cause fluctuations, make the tire lateral uniformity improve grip strength, is helpful to control the movement of the article to the edge of fiber. Pu castor chemistry performance is good, suitable for all types of printing ink and printing method. In all kinds of liquid, detergent, ink solvent composition has a special resistance to resistance. Pu castor also applies to the UV ink castor and glazing castor oil, etc. , especially to the boiling water, diesel, gasoline, kerosene, toluene, alcohol, lubricating oil and brine solution with good solvent resistance. But not acetone, ethyl acetate and acid alkali resistance. Where the requirements to prevent the accumulation of electrostatic generation, had better use special anti-static wheel, also can choose metal wheel ( If the ground does not require protection, ; Work environment there are many corrosive medium, should choose to have good corrosion resistance of the wheel accordingly. Hard foam is mainly used in household appliances waterproof spray foam insulation layer, the house wall, pipe insulation materials, building plank, refrigerator and cold storage insulation material, etc. ; Half hard foam used in automobile dashboard, the steering wheel, etc. Market has polyurethane foam composite materials that are used for various specifications ( Two-component premix) Mainly used for ( Cold cure) High resilience foam, half hard foam plastic, casting and spraying hard foam plastic, etc. More news and information about pu castor please click: hynews / 290. html
