Today, belts in both the automotive and the industrial/agricultural sectors are being required to transmit ever higher forces. More and more aggregates are being driven by single belts, so to extend their lifetimes, belt components need to have high resistance to fatigue. In addition, in the automotive industry, belts are increasingly replacing metal chains as part of the drive to reduce CO2 emissions. SKS offers a range of high-tech cords that allow belt manufacturers to meet these new demands and develop their products accordingly.

Polyester (PET):

• Available as twisted and RFL-dipped cord for excellent adhesion, in a wide variety of tailormade plied constructions
• Soft-dipped as well as semi-stiff-dipped for improved fray resistance

Aramid:

• High breaking tenacity with low elongation and creep for excellent power transmission
• High flexibility and dimensional stability, and good chemical and heat resistance
• Available as twisted and RFL-dipped cord for excellent adhesion, in a wide variety of tailormade plied constructions.

Monofilament Polyamide (PA6):

• High uniformity in linear density, diameter, surface properties and shrinkage to ensure high stability
• Available as twisted cord and in a wide variety of tailor-made plied Constructions

Hybrids:

• High uniformity in linear density, diameter and shrinkage to ensure high stability with tailored and optimized surface properties
• Available as twisted cord and in a wide variety of tailor-made plied constructions

Twisted monofil

All RFL-dipped yarns have excellent properties of adhesion to commonly used rubber compounds, like EPDM, NR, SBR, and CR. Yarns can also be tailored to optimize adhesion to customer-specific rubber compounds.
 

High uniformity and clean, perfect processing are the key requirements that today’s
tire manufacturers have of Single End Cord (SEC). The use of SEC in specific production methods is gaining ground due to higher efficiency and flexibility of the
manufacturing process. For many years, SKS has been a key supplier of SEC, offering
a tailored portfolio of high-tech SEC.
