PEX pipe, also known as cross-linked polyethylene pipe, is made of polyethylene material. The linear molecular structure of polyethylene is transformed into a three-dimensional network structure through physical and chemical methods, thereby improving the performance of polyethylene.
The main raw material of PEX pipe is HDPE, as well as initiators, cross-linking agents, catalysts and other additives. If there are special requirements, other modifiers can also be added.
The main raw material for the production of PEX pipes is HDPE, as well as initiators, cross-linking agents, catalysts and other auxiliary agents. If there are special requirements, other modifiers can also be added.
The PEX tube is manufactured by the world's advanced one-step (MONSOIL method) technology. It uses ordinary polyethylene raw materials to join the silane grafting material to form chemical covalent bonds between polymer macromolecular chains to replace the original van der Waals force, thereby forming a three-dimensional The cross-linked polyethylene with a cross-linked network structure has a cross-linking degree of 60% to 89%, which makes it have excellent physical and chemical properties.
Production Process
Raw material pretreatment + auxiliary agent preparation → mixing → melt graft extrusion → pipe forming → cross-linking → inspection packaging → finished product.
The role and purpose of additives
The cross-linking agent cracks the original linear molecular structure to form a graft material, and then forms a three-dimensional network structure. The role of antioxidants and color particles is to improve the corrosion resistance of the PEX tube, prevent long-term sunlight exposure from changing physical properties, and can resist long-term erosion of ultraviolet rays, thereby extending its service life.
