PET Tire Cord

Since starting production of polyester tire cord in 1978, Hyosung now deals with high quality polyester tire cord for tire reinforcements, including regular-type and more advanced stable-type (High Modulus Low Shrinkage) polyester tire cord (which is called HSP). The more advanced HSP series are marketed through Hyosung's continued research and development. The internally developed dipping technology enables Hyosung's PET tire cord products to be recognized for their outstanding adhesive force.

Hyosung's recent research and development activities are aimed at more advanced polyester tire cord fabrics with excellent dimensional stability.

Features
Excellent dimensional stability
Cheaper than other materials, mainly used for radial tires for passenger cars
Applications
Tires for passenger cars and light-duty trucks
