Brake hoses must remain flexible while maintaining their volume at a constant level under pressure load. Only this way the braking force can be transmitted to the tires in an effective and reliable manner. Brake hose reinforcement is therefore made of textiles; brake hoses reinforced with CORDENKA® rayon demonstrate excellent levels of volume constancy under pressure load … at both low and high temperatures.
This excellent volume constancy – even under rising temperatures – is one of the major benefits of brake hoses reinforced with CORDENKA® rayon and constitutes a clear advantage over other thermoplastic fibers, as well as PVA. CORDENKA® rayon-reinforced brake hoses make sure that the braking force gets to where it is needed, and that a touch of the pedal – even under extreme conditions – gives the driver the sense of safety he or she can count on at all times.
In addition to these favorable mechanical properties, CORDENKA® rayon’s resistance to chemicals is essential to hose applications and makes it popular for use in hoses for fuel/petrol pumps and feeder hoses in the chemical industry.
As a multifilament yarn, CORDENKA® rayon is perfectly suited for all major hose production techniques and is valued for its good processing features. Its extremely low heat shrinkage, for example, forms a crucial factor in hose production.
