The core application fields of high-strength polyester industrial filament: The core of industrial "skeleton materials"!

high-strength polyester industrial filament is a key material connecting "chemical fibers" and "high-end manufacturing", and is widely used in fields such as automobiles, infrastructure, chemical engineering, and transportation. The specific scenarios are as follows:

Automobile worker

Tires: As "radial tire cord fabric" (accounting for over 60% of the tire skeleton material), it replaces traditional cotton cord, enhancing the strength, wear resistance and lightweight level of tires.

Transmission system: It is used as the skeleton layer of automotive V-belts and synchronous belts, bearing dynamic tension and reducing belt body deformation.

Infrastructure and Geotechnical Engineering

Geotextile/geogrid: Used as anti-seepage/reinforcement layer for expressways, DAMS and landfill sites, it can resist soil settlement and water flow erosion with its high strength.

Water conservancy projects: Making flood control sandbags and reinforcing layers of anti-seepage membranes, which are resistant to water erosion and not easy to degrade.

Industrial conveyor belts and rubber hoses

Conveyor belt: As the "core layer skeleton" (such as conveyor belts in coal mines and port terminals), it bears the weight of materials and the conveying tension, is wear-resistant and tear-resistant.

High-pressure rubber hoses: Used as the reinforcing layer of hydraulic rubber hoses and oil transportation rubber hoses, they resist the impact of high-pressure media and prevent the hoses from bursting.

Special ropes and nets:

Ships/Oceans: Manufacturing ship mooring lines and Marine aquaculture nets, resistant to seawater corrosion and with high strength (replacing traditional steel wire ropes, reducing weight by more than 50%);

Outdoor rescue: Used for climbing ropes and safety ropes for high-altitude operations, it features high breaking strength and moderate elongation (avoiding impact injuries caused by sudden breakage).

Other fields of high-strength polyester industrial filament

Filter material: Used for high-temperature flue gas filter bags (such as in power plants and waste incineration plants), it is heat-resistant (≤150℃) and tensile resistant.

Composite materials: As reinforcing fibers for fiberglass reinforced plastic (FRP), they are used in wind turbine blades and automotive parts to enhance the strength and weather resistance of composite materials.
