High strength aramid Kevlar 400D-1500D with excellent thermal stability and high temperature resistance PARA filament yarn
The top technology in the field of synthetic fibers redefines the performance boundaries of industrial protective materials with Kevlar grade strength and ultimate heat resistance.
Analysis of Core Advantages
Ultra high strength and lightweight
Kevlar grade mechanical properties: fracture strength up to 20-30cN/dtex (5 times higher than steel wire), with a denier range of 400D to 1500D covering different load-bearing requirements, while maintaining extremely low density (1.44g/cm³), achieving a lightweight revolution of “replacing steel with yarn“.
Impact toughness: The rigid structure of the molecular chain endows it with excellent energy absorption ability, and its resistance to repeated impact fatigue far exceeds that of ordinary synthesis Fiber .
Extreme heat resistance and thermal stability
High temperature non melting and non dripping: Long term use temperature above 200 ℃, short-term temperature resistance exceeding 500℃, ultimate oxygen index (LOI) ≥ 28%, belonging to essential flame retardant material .
Thermal shrinkage rate<0.5%: Excellent dimensional stability in high temperature environments, avoiding structural failure caused by thermal deformation, suitable for hot processing environments (such as tire cords and high-temperature conveyor belts).
Chemical and Environmental Tolerance
Resistant to strong acids ,strong alkalis 、And organic solvent corrosion,Anti UV aging、Excellent performance, maintaining performance without degradation in extreme weather or industrial corrosion scenarios.
Breakthrough in application scenarios
In the field of safety protection:firefighting suits,cut resistant gloves,armor lining, utilizing their high strength and high temperature resistance to construct a life defense line.
High end industrial components: Aircraft flame retardant cabin curtains,High temperature filter bags , Fiber optic cable tensile cores , replacing metal to reduce system load.
Composite reinforcement material: as 、resin 、 Base、Rubber Reinforced skeleton of composite materials to enhance heat and compression resistance (such as F1 racing brake pads) High pressure resistant hose ）.
Technical value positioning
This long filament yarn achieves a perfect balance between strength and heat resistance through the directional arrangement of aramid (PARA) molecular chains and high crystallinity control. Compared to traditional meta aramid (such as Nomex) , its axial tensile modulus is increased by more than 50%, and its thermal decomposition temperature exceeds 550℃, making it an irreplaceable solution for high-temperature and high-strength scenarios.
Conclusion: This aramid filament yarn has the triple characteristics of 、stronger、 lighter、 more heat-resistant “, providing a disruptive material choice for aerospace, special protection, high-end manufacturing and other fields. It can be called the ” fiber armor ” in the industrial evolution process.
