New Long Acid and Alkali Resistant Chemical Vessels, made of polyethylene (LLDPSE、HDPE) Based on raw materials, we blend low-density linear polyethylene with high-density polyethylene in a rational formula to ensure rigidity and toughness. Utilizing a one-time, whole molding technique, the product is seamless and leak-proof. It boasts high strength, corrosion resistance, lightweight, resistance to aging and impact, non-toxicity, and a 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 a steel-lined plastic (outer steel, inner plastic) series of storage tanks, reactors, and transportation tanks.
