Qingdao Tianzhida High-tech Industrial Development Co., Ltd. is a company integrating development, production, sales, and service Private enterprise entity 。Established in 2008 ，The company's predecessor was Qingdao Tianzhida Plastics Integration Co., Ltd. From its inception, the company has adhered to High starting point 、 High Quality and excellent service-oriented business philosophy, enabling the company to expand rapidly and quickly become an industry Leader 。The company has Panel Materials Division (Production of PE PP sheet materials), Hot Melt Division (Research and development and production of hot melt and heat shrink products) and Welding Division (Processing and manufacturing of plastic finished and semi-finished products). Currently, the company's Reinforced heat shrink tubing 、 Reinforced electrothermal fusion tubing and Reinforced PE sheet ，By adding reinforced fibers to the normal process, the tensile strength of the product is doubled, filling the gap in the market.

The 3PE heat shrinkable tape series products are designed for the corrosion protection of buried and overhead steel pipe welds and the insulation of insulation pipes. It is composed of radiation cross-linked polyolefin base material and special sealing hot melt adhesive. When constructing, it is used with two-component epoxy primer. The special sealing hot melt adhesive can form good adhesion with the polyolefin base material, steel pipe surface and solid epoxy coating. When the WK-WSS3PE heat shrinkable tape is heated and installed, the base material shrinks radially, while the internal composite adhesive layer melts and tightly wraps around the joint, forming a strong anticorrosion body on the outside of the pipe together with the base material. It has excellent wear resistance, resistance to soil stress, resistance to static water pressure, impact resistance, and good resistance to ultraviolet light and photoaging. At the same time, it has resistance to chemical corrosion and mildew corrosion. In addition, the 3PE heat shrinkable tape is called a live sleeve in the industry, compared to the heat shrink sleeve called a dead sleeve. In addition to the 3PE heat shrinkable tape body, it is also equipped with a rubber strip and a fixing plate, and the 3PE heat shrinkable tape is easy for mass production, and the construction is quick and convenient.
