Application Fields of Zhongtai PVC Resin
- Construction industry. Used to manufacture door and window profiles, pipes, plates, etc. For example, PVC pipes have the characteristics of corrosion resistance, wear resistance, and low water flow resistance, and are widely used in water supply and drainage systems; PVC door and window profiles have good sealing, thermal insulation and weather resistance, which can effectively improve the energy saving effect and service life of buildings.
- Medical field. Medical-grade high-polymerization PVC resin can be used to manufacture medical devices, medical packaging, etc. For example, some medical catheters, infusion bags, etc. are made of Zhongtai medical-grade PVC resin, which has good biocompatibility and stability, ensuring the safety and reliability of medical supplies.
- Electronic and electrical industry. As the insulation layer and sheath material of wires and cables, as well as the manufacturing material of home appliance housings. The electrical insulation and mechanical properties of Zhongtai PVC resin can effectively protect the conductors inside wires and cables, prevent leakage and short circuits, and provide good appearance and protection performance for home appliance housings.
- Other fields. It is also widely used in automotive interior parts, daily necessities, packaging materials, etc. For example, PVC materials are used in car dashboards, seat fabrics, floor mats and other parts; raincoats, slippers, toys and other daily necessities are also often made of PVC resin; in the packaging field, PVC films and sheets are used for the packaging of food, medicines, cosmetics, etc., and have good transparency and barrier properties.
