Tianyi New Material (300169) has recently obtained two invention patent certificates issued by the State Intellectual Property Office, namely styrene butadiene rubber foam board and its preparation method, an improved cross-linked polyvinyl chloride structural foam and its preparation method. . The announcement shows that the two patented technologies are directly related to the company's main technology. Among them, the styrene butadiene rubber foam sheet and the preparation method thereof can improve the environmental performance, mechanical properties, elasticity, and cold resistance of the soft foam product. In addition, an improved cross-linked polyvinyl chloride structural foam and a preparation method thereof relate to a structural foam core material which constitutes a composite sandwich structure and can provide high-strength, light-weight, sound-insulating, and flame-retardant properties as a sandwich structure. Into a building curtain wall, you can reduce the weight of the wall, improve the thermal insulation effect of the wall, and have good sound insulation, flame retardant and corrosion resistance. The announcement shows that the above-mentioned patented technology has been applied to the company's existing product production, and the acquisition of the patent is expected to have no major impact on the company's production and operation within the next year, but it will help the company to give full play to the advantages of independent intellectual property rights and enhance the company's core competitiveness. . recision automotive circuit connectors,, electrical appliances,transmission bearings ,detecting head,ABS insert mould , POM Insert mould, PA66 Insert Mould, PA6+GF insert mould Dongguan Hongke Plastic Precision Mould Co.,Limited , https://www.hongkemolds.com
