PVC cables are made from Polyvinyl Chloride (PVC) and offer good flame retardancy and physical properties, but may produce toxic gases and dense smoke when burned. PE cables, on the other hand, use Polyethylene (PE) as the insulating material, known for its excellent dielectric properties and low-temperature resistance, making it suitable for the insulation of high-voltage cables
Compounding Ingredients of Engineering Plastics
1. Base Resins: The foundation of engineering plastics typically consists of high-performance polymers such as polycarbonate (PC), nylon (PA), polybutylene terephthalate (PBT), polyether ether ketone (PEEK), and polyoxymethylene (POM).
2. Reinforcements: To enhance mechanical and thermal properties, fiber reinforcements like glass fibers, carbon fibers, or aramid fibers are often added.
3. Additives: Include antioxidants, thermal stabilizers, UV absorbers, lubricants, flame retardants, impact modifiers, etc., used to improve the material’s performance and processability.
4. Fillers: Filler materials such as minerals (talc, mica) or metal powders may be added to increase hardness, improve dimensional stability, or reduce material costs.
Classification
1. By Type:
Non-reinforced engineering plastics: These materials do not contain reinforcements such as glass or carbon fibers and are typically used in applications where mechanical strength requirements are not exceptionally high.
Reinforced engineering plastics: Enhanced with glass fibers, carbon fibers, or other reinforcing materials to improve their mechanical and thermal properties, suitable for areas requiring high strength and heat resistance.
2. By Application Sector:
Electronics and Electrical Engineering Plastics: Offer excellent electrical insulation and thermal stability, ideal for use in electronic and electrical components.
Automotive Engineering Plastics: Possess high temperature resistance, wear resistance, and high strength, suitable for load-bearing parts in automobile manufacturing.
Aerospace Engineering Plastics: Provide stability under extreme temperatures and chemical corrosion environments, used in the aerospace field for high-performance requirements.
Medical Grade Engineering Plastics: Comply with stringent biocompatibility and non-toxic standards, used in medical devices and packaging.
3.Other Classifications:
General Purpose Engineering Plastics: While possessing the basic characteristics of engineering plastics, these materials have relatively lower performance indicators and are used for general engineering applications.
High-Performance Engineering Plastics: Exhibit exceptional thermal stability, chemical resistance, and mechanical strength, suitable for high-end engineering applications such as metal replacement, high-performance sports equipment, etc.
Specialty Engineering Plastics: Designed for specific applications, such as ultra-high or ultra-low temperature environments, special chemical or radiation environments, used to meet unique industry needs.
Applications
● Automotive Sector: Using PA66 and PA6 compounds, automotive components such as intake manifolds, header tanks, filters, fans and shrouds, and engine covers achieve high temperature resistance, weight reduction, and enhanced corrosion resistance, thereby improving fuel efficiency and extending service life.
● Electrical Applications: Components like terminal blocks, cable ties, connectors, power tools, MCCB, relays, and lights manufactured using ABS and PBT compounds offer excellent insulation, wear resistance, and thermal stability, ensuring safe operation of equipment under high voltage and temperature conditions.
● Blow Molding: PET and BOPET compounds used for medical and cosmetic containers, lubricant and paint containers provide high transparency, chemical resistance, and recyclability, while ensuring product safety and environmental friendliness.
● Film and Pipe Extrusion: Compounds used for BOPA, PET sheet, pipe, etc., feature high strength, gas barrier properties, and durability, making them suitable for food and beverage packaging and ensuring long-term food safety and freshness.
● Fiber Applications: Fiber products such as PA fiber, PSF, FDY, PSF leverage the tensile strength, heat resistance, and lightweight characteristics of engineering plastics, widely used in high-performance ropes, fabrics, sports equipment, and outdoor goods.
