1. Good processing performance: Taking the Erdos PVC SG5 model as an example, it has satisfactory low-temperature melting and flow characteristics, which is convenient for matching various plastic products through various processing methods such as extrusion and injection molding. It can also be blended with additives such as plasticizers and stabilizers to meet the needs of different products.
2. Strong chemical stability: This resin has high chemical resistance, is not easily corroded by general chemicals, has good water resistance, and can be used for manufacturing corrosion-resistant pipes, pipe fittings, chemical tank linings, etc., and can be used safely in a variety of chemical environments.
3. Excellent insulation: Erdos PVC resin has good electrical insulation performance and is non-conductive. It can be used to manufacture insulation layers of wires and cables, plugs, sockets, switches and other electrical and electronic components, which can effectively ensure the safety of electricity use.
4. Outstanding physical properties: It is non-toxic and odorless, with a relative density between 1.35u20131.45. It is a thermoplastic resin, insoluble in water, gasoline and ethanol, and can swell or dissolve in solvents such as ether and ketone. It has a certain rigidity and hardness. Hard PVC products can be used to manufacture products that require strength, such as doors and window profiles.
5. Good flame retardancy: The Erdos PVC resin has certain flame retardancy and is easy to extinguish after leaving the flame. This feature improves its safety in applications in construction, home furnishing and other fields. It can be used for wire sheathing, building decoration materials, etc.
6. Excellent weather resistance: It has good weather resistance and is not easy to age quickly and degrade performance due to long-term exposure to sunlight, rain and other environments when used outdoors. It is suitable for manufacturing outdoor plastic products, such as door and window profiles, outdoor billboards, etc.
