Our company's EN900 and EN910 series polyolefin wear-resistant pipe materials, through our blending modification technology and fluorinated silicon grafting modification technology, endow the polymer with specific functionalities, making them a special type of elastomer material. They possess excellent wear resistance, good mechanical properties, and processing performance. They have good compatibility with pipe materials such as polyethylene and polypropylene, and are suitable for double or multi-layer co-extrusion due to their matching extrusion speed. Their excellent wear resistance makes them particularly suitable for conveying abrasive media such as mortar and slag.

Our EN300 series adhesive resin is developed using advanced reactive grafting extrusion modification technology . It boasts stable performance, strong adhesion, good processing fluidity, excellent compatibility with polyolefin resins, and excellent chemical bonding strength with steel wire and copper-plated steel wire. It offers superior bonding durability, is hygienic and safe, and leaves no toxic residue. It exhibits excellent adhesion to various types of steel wire and good processing performance!

Our company's color masterbatch uses high-quality imported pigments as the main raw material, selects polyolefin resin as the carrier, and is treated with highly active surface modifiers, coupling agents and compatibilizers. It is processed by twin-screw extrusion and is suitable for color matching of PE modified plastics.

Donghong black masterbatch is formulated using virgin resin as a carrier, along with selected pigments, carbon black, and high-quality functional additives. The product formula undergoes rigorous screening and optimization, and the advanced production equipment and strictly controlled processes ensure stable product quality. This series of products is odorless, smokeless, non-toxic, and environmentally friendly during use. It also possesses excellent dispersibility, imparting good blackness and gloss to customer products, excellent weather resistance, and a smooth appearance, without adversely affecting the physical and mechanical properties of the product. Using Donghong black masterbatch offers advantages such as improved product quality, reduced production costs, and reduced pollution.

Our company's EN700 series 3PE pipe anti-corrosion material is a black high-density polyethylene compound suitable for the outer coating of steel pipes. It has good physical and mechanical properties, electrical properties, excellent resistance to environmental stress cracking, UV aging, heat aging, and various chemical properties such as acids, alkalis, and salts.
