Pingxiang Rongjian Environmental Protection Chemical Packing Co., Ltd.

Hiabrub Rubber (Hengshui) Mechanical Technology Co., Ltd. (hereinafter referred to as "Haibo Rubber") was formerly a state-owned holding enterprise and is now a high-tech enterprise specializing in the research and development, customized production, and provision of system solutions for high-performance rubber and plastic products. The company adheres to the business philosophy of "building on integrity, establishing trust through quality, and establishing business through innovation", continuously introducing international cutting-edge processes and intelligent manufacturing technologies, simultaneously promoting energy conservation, reduction of waste, and lean production, and continuously enhancing the capabilities of large-scale, standardized, and flexible delivery. Relying on its independent research and development capabilities and strict quality control system, the company's products have been widely used in fields such as national defense and military industry, chemical industry, metallurgy, food processing, energy equipment, and high-end equipment manufacturing, and have received high recognition from industry customers. Main products include: Special industrial pipe series (such as food-grade hygiene pipes, high-temperature steam pipes, chemical corrosion-resistant pipes, wear-resistant concrete conveying pipes, high-pressure well control pipes for oil drilling, large-diameter marine oil and gas transportation composite pipes, PTFE-lined metal composite pipes, engine fuel conveying pipes, high-temperature hot oil pipes, etc. ); 3D printing dedicated high-performance wires (covering the full range of original factory raw materials such as PETG, PLA, ABS, 100% prohibited recycled materials); Precision rubber and plastic sealing components (including O-rings, Y-shaped sealing rings, UHS-type oil seals, various elastic gaskets, food-grade sealing pads, NBR/FKM/EPDM material mechanical seals and engine-specific sealing systems); Petroleum drilling dedicated high-pressure elbows and multi-material (metal/ engineering plastic) high-precision machining parts. The company has passed ISO 9001: 2015 quality management system certification and continuously improves comprehensive management systems such as environment, occupational health and safety. Looking to the future, Haibo Rubber will continue to strengthen R&D investment, optimize the full-cycle customer service mechanism, and strive to become a trusted provider of special high-molecular material application solutions.

The company produces and exports various fluid sealing products and materials. Main business: PTFE products (processed parts), packing materials, sealing gaskets, anti-corrosion steel-lined pipe fittings and tanks (plastic-lined), etc. The products are applied in industries such as petrochemical, oil refining, power, shipbuilding, semiconductors, new energy, nuclear power, and military. Meanwhile, the products are exported to Europe, America, the Middle East, South Korea, Japan, and Southeast Asian countries and regions. Polytetrafluoroethylene (commonly known as plastic king) has excellent comprehensive properties such as corrosion resistance, high temperature resistance, aging resistance, high insulation, high lubrication, non-adhesion, etc., and is widely used in aviation, chemical, electronics, machinery and other industries. The white and black combined seal ring is used for ISO-TANK (international standard container, referred to as tank box, mainly used for the transportation of dangerous chemicals) tank mouth seal. The sealing ring used in the tank is divided into ordinary sealing ring and super sealing ring, commonly known as white and black (that is, white and black combined sealing ring). Domestic and foreign fluorine-coated D-type sealing rings are joint products, and the tetrafluoroethylene joint part is damaged by the sodium layer during high-temperature melting, which directly affects the adhesion between the tetrafluoroethylene film and the rubber body. In addition, the parting surface of the product mold is on both sides of the sealing ring, so the inner ring of the product inevitably appears the parting surface flash, which not only affects the appearance of the product. Mperature resistant silicone rubber O-ring and low pressure variable fluorine rubber O-ring is determined. Inorganic fillers were used to fill and blend modified fluorine plastics, and the types and dosage of fillers were studied. Independently developed mold structure, under the condition of precise positioning of rubber O-ring, injection modified fluorine plastic method to achieve a molding, full coating process. Main technical indicators: According to JB/T 10706-2007, fluorine plastic fully coated silicone rubber O-ring: Tensile strength
