UPVC profiles

17 Jun, 2024

Material characteristics: UPVC profiles are made of polyvinyl chloride resin and specific additives (such as stabilizers, lubricants, fillers, etc.) through a specific process. It is the 1 kind of hard, non-toxic, tasteless plastic material, with good environmental performance.
UPVC profiles have excellent weather resistance, chemical resistance, insulation properties and mechanical properties.
Application: UPVC profiles are widely used in the construction industry, commonly used in doors and windows, pipes, wall panels, ceilings and other building materials. It is also used in water piping engineering, water-saving irrigation piping engineering, post and telecommunications cable conduits, chemical plant infusion piping and other fields.
Production process:
The production process of UPVC profiles includes ingredients, mixing, extrusion, cooling and shaping, traction and cutting, inspection, packaging and other steps.
The batching process requires precise control of the ratio of various raw materials, including more than ten materials such as PVC, heat stabilizers, fillers, and lubricants. Extruder is the key production equipment, which uses external heating and screw shear force on the material to make PVC PVC powder plasticized into a molten state.
Performance advantages: because the UPVC material has the characteristics of acid and alkali resistance, corrosion resistance, no rust, no scaling, etc., UPVC profiles can effectively protect water quality and avoid secondary pollution of water quality. It also has good insulation properties and can effectively block the conduction of current. UPVC profiles have high strength, rigidity and toughness, which can meet the requirements of building materials for strength, stability and durability.
Note: due to the high melt viscosity of UPVC, easy to decompose, the decomposition products have a corrosive effect on the metal, the injection molding must use special plasticizing parts and temperature control system. In the production of UPVC profiles, it is necessary to strictly control the ratio of raw materials and the feeding sequence, as well as the time, temperature, speed and other parameters of the mixer to ensure product quality.
