Special polyurethane tubing

KKS Flame-resistant special polyurethane tubing

With approvals according to railway standard DIN 5510-2

Keep safety on the right track: KKS special tubing made of halogen-free, flame-resistant polyurethane (PUR) works reliably wherever pneumatic tubing has to meet strict fire protection standards, fire protection directives and statutory fire protection requirements. With its optimized material composition, KKS pneumatic tubing also achieves excellent mechanical properties that have proven themselves in practice for years, even under the toughest operating conditions.

High durability Flame-resistant polyurethane tubing

The versatile durability and high resistance of KKS special tubing enable its use in a wide variety of environments and guarantee a long service life even with above-average workloads. The self-extinguishing and flame-resistant polyurethane tubing is resistant to hydrolysis and microbes, and has good resistance to UV rays and a large number of chemicals, cleaning agents, solvents or other contact agents. The self-extinguishing special tubing is therefore qualified for applications in which flame-resistant materials are required, e.g. in aircraft, in building technology or in rail vehicles.

Suitable for vacuum applications, recyclable & easy to install

The developers at PAPUREX think long-term and always take a holistic approach to special tubing. This means that in addition to the primary functionality, secondary aspects are also taken into account. Accordingly, KKS special polyurethane (PUR) tubing is suitable for operating pressures of up to 8 bar as well as for work areas with a vacuum of up to -0.95 bar, depending on the temperature in each case. In addition, our polyurethane tubing can be used with plug-in connections from all leading manufacturers, which ensures fast and easy installation. Due to the use of sustainable materials, KKS special tubing is 100% recyclable
