New Dragon Acid and Alkali Resistant Chemical Vessels made of PolyethyleneLLDPSE、HDPE) Utilizing raw materials, we blend low-density linear polyethylene with high-density polyethylene in a rational formula to ensure rigidity and toughness. The products are formed using a one-time, seamless, and leak-proof molding technique. They feature high strength, corrosion resistance, lightweight, aging resistance, impact resistance, non-toxicity, and long service life. Our company independently developed the rotational molding production process and has successively launched various sizes of full plastic storage and transportation tank series. We have developed steel-lined plastic (outer steel, inner plastic) series storage tanks, reactors, and transportation tanks.
