Low smoke halogen-free wire and cable material is made of halogen-free crosslinked polyethylene flame retardant material, the halogen content is about half of the halogen flame retardant cable, the smoke amount is also close to the recognized "low smoke" level. It not only has better flame retardant characteristics, but also does not release halogenated gas or other acids when it is on fire, which can reduce the toxic and corrosive gases produced when it is burned.

Wire and cable

PVC insulation materials have good reliability and safety properties, including chemical resistance, wear resistance, flame retardancy and good insulation properties. Compared with other insulation materials, it has the advantages of low price, easy processing and good insulation performance.

Medical industry

Modified pvc and PE plastics can be widely used to make blood storage bags, blood transfusion bags, as well as blood ducts, artificial peritoneum, artificial urethra, bag artificial lung, cardiac catheters and artificial heart and other products. In addition, the composite membrane composed of LDPE, PA and PE has the advantages of pvc and PP bags and is widely used.

Daily necessities industry

Daily plastic products generally use PE and PP raw materials, such as wash basin, iron bucket, laundry pool, plastic anvil, plastic chair but mineral water bottle, transparent medicine bottle is better to choose PET, bright gift packaging box tank, decoration design lamp, wall lamp, ceiling lamp plastic components, often used PS.

Electronic and electrical industry

PC plastics are often used in LED lamps, monitors, camera shells and other high-grade electronic products. PP plastics are often used in electronic products such as Jack, plug and other spare parts, but also can be used in the manufacture of mobile phone shells. PE plastics are often used in electronic products such as sealing rings, gaskets and other parts, but also can be used in the manufacture of vehicle electrical accessories. POM plastics are often used in the manufacture of switches, plug-ins, sliders and other precision spare parts in electronic products. PA plastics are often used in the manufacture of bearings, gears, connectors and so on in electronic products.

Automobile industry

The main plastics commonly used in automobile interior and exterior decoration parts are PP class, PC/ ABS class, ABS class, PE class, PA class and POM, among which the largest amount is PP material.

New energy

New energy power battery structure: support, frame, end plate, optional materials are flame retardant PPE, PC/ABS alloy and flame retardant reinforced PA. PPE density 1.10, PC ≤ ABS density 1.2, enhanced flame retardant PA1.58g/cm, from the point of view of weight loss, the main choice of flame retardant PPE.

Home appliance industry

General plastics for household appliances: ABS, HIPS, GPPS, PP, etc.; high surface requirements: color, finish, luster, hardness, printing properties, etc.; better mechanical properties, thermal properties, aging resistance; flame retardancy, electrical insulation properties; better processing properties, dimensional stability; cheap price.

PTFE material properties

PTFE (polytetrafluoroethylene) is a thermoplastic with a range of excellent properties. The following is a detailed analysis of PTFE material properties: 1. Chemical stability: PTFE has very high chemical stability, almost insoluble in all strong acids, strong bases, strong oxidants, reducing agents, etc., including concentrated sulfuric acid, nitric acid, and even boiling in aqua regale, its weight and performance are unchanged. This property makes it widely used in many chemical reactions. 2. Corrosion resistance: PTFE does not absorb moisture, non-flammable, extremely stable to oxygen and ultraviolet light, so it has excellent weather resistance. Even high-energy radiation can not cause degradation, so that it can still maintain stable performance in harsh environments. 3. High temperature resistance: PTFE can be used in a wide area of -250 ~ 260 ° C, even at ultra-low temperatures of -260 ° C can still maintain a certain degree of flexure; At 260℃, its breaking strength remains about 5MPa (about 1/5 of room temperature), and its bending strength reaches 1.4MPa. This gives it excellent performance in high temperature environments. 4. Electrical properties: The electrical properties of PTFE are also excellent, the dielectric constant and dielectric loss are very low, and the breakdown voltage, volume resistivity and arc resistance are high. This makes it widely used in fields such as electronic equipment and wire and cable. 5. Biocompatibility: PTFE has excellent biocompatibility and is widely used in the manufacture of medical devices and biological materials. This characteristic makes it have wide application prospect in medical field. Molding performance: PTFE has good fluidity and is easy to injection, extrusion and blow molding. Its small shrinkage rate and good dimensional stability make the accuracy and appearance quality of PTFE products guaranteed. Yonghesheng creates the world's leading products to meet the individual needs of more customers. Please refer to https://www.shyhsgroup.com/ Purchasing plastic particles please contact https://www.shyhsgroup.com/, medical materials, please contact Yonghesheng quotation E-mail: Aden@shyhsgroup.com; Leo@shyhsgroup.com ;   In general, PTFE has excellent properties, making it in the semiconductor, automotive parts, electrical appliances, construction, oil and gas exploration, medical and other fields have a wide range of applications. However, it should be noted that the cost of PTFE is relatively high, and environmental protection and safety issues need to be paid attention to during processing and use.
