Kevlar Twaron Aramid Fiber for Kevlar Ropes Webbing Sewing Thread

Product Description

Para Aramid Filament Fiber
Para - aramid fiber is a high - performance synthetic fiber.
Molecular Structure
The molecular structure of para - aramid fiber is based on aromatic polyamide. It consists of repeating units of amide linkages (- CONH - ) connecting aromatic rings. The aromatic rings provide rigidity to the molecular chains. The chains are highly oriented and parallel to each other. This ordered structure is a key factor in its excellent mechanical properties. For example, it's like a well - organized of molecular soldiers standing in a straight line. The amide linkages help in holding the structure together, while the aromatic rings give strength and stability, making it a remarkable material for applications that demand high strength and resistance to various external factors.
Features
1.High Strength
It has excellent tensile strength. The molecular chains of para - aramid are highly oriented and closely packed, enabling it to withstand heavy loads.
2.Good Thermal Stability
Para - aramid filament can maintain its performance at high temperatures. It has a high melting point and can resist thermal degradation. It can work stably in relatively harsh thermal environments without significant loss of mechanical properties.
3.Chemical Resistance
It shows good resistance to a variety of chemicals. It is not easily corroded by acids, alkalis and some organic solvents, which makes it suitable for use in chemical - intensive environments.
Application Areas
1. Personal Protective Equipment:
- Bulletproof vests and helmets: Due to their exceptional strength and durability, para-aramid filaments are a key component in making bulletproof vests and helmets, providing reliable protection against bullets and shrapnel.
- Firefighter suits and workwear: These filaments are used in the production of firefighter suits and workwear for high-risk occupations such as those in the petrochemical and welding industries. They can withstand high temperatures and are flame-retardant, protecting the safety of workers.
2. Aerospace and Aviation:
- Aircraft components: Para-aramid filaments are used in the manufacturing of aircraft components such as brake linings, engine parts, and heat shields. Their high heat resistance and strength make them suitable for use in high-temperature and high-stress environments in aircraft.
- Aircraft interiors: They are also used in the interiors of aircraft, such as for floor panels, ceiling panels, and sidewalls, to reduce the weight of the aircraft while maintaining strength and fire resistance.
3. Automotive Industry:
- Tires: Para-aramid filaments can be used in tire manufacturing, especially in the production of high-performance tires. They help improve the tire's strength, durability, and resistance to abrasion, enhancing the overall performance and safety of the tires.
- Brake pads: The high-temperature resistance and strength of para-aramid filaments make them suitable for use in brake pads, ensuring reliable braking performance even under high-temperature conditions.
4. Optical Communication:
- Fiber optic cables: Para-aramid filaments are used as strength members in fiber optic cables to enhance the cable's tensile strength and protect the optical fibers from external forces, ensuring the stable transmission of optical signals.
5. Industrial and Engineering Fields:
- Conveyor belts: In industrial production, conveyor belts need to withstand heavy loads and high friction. Para-aramid filaments can be used to reinforce conveyor belts, improving their strength and service life.
- Ropes and cables: High-strength ropes and cables used in construction, marine, and other fields can be made with para-aramid filaments, providing excellent tensile strength and durability.
6. Sports and Leisure Equipment:
- Sports gear: Such as high-performance sports shoes, tennis rackets, and badminton rackets, can use para-aramid filaments to enhance the strength and impact resistance of the equipment, improving the performance and service life of the sports gear.
- Outdoor equipment: Para-aramid filaments are also used in the production of outdoor equipment such as tents and backpacks, making them more durable and lightweight.
