Straightforward Explosion Protection
The ATEX Directive (European standard EN 13436) regulates explosion protection for nonelectrical systems, devices, and components in potentially explosive atmospheres. The primary focus for manufacturers is on selecting materials with specific physical properties in order to avoid possible electrostatic discharge. Crucial characteristics include bending and tensile strength, temperature resistance, resistance to tracking, surface resistance, electric strength, flammability, light resistance, and chemical resistance.
Components made from PTFE and PTFE compounds are a suitable choice for applications requiring explosion protection in accordance with ATEX thanks to their excellent long-term temperature resistance, chemical resistance, and UV stability. LOI values and a “UL 94 Flame Class“ rating of 94V-0 also illustrate the low flammability of these products. High-grade conductive PTFE compounds that meet electrical requirements (resistance to tracking, surface resistance, and electric strength) are also available. With a temperature resistance of around 180°C, the RTI values according to UL are also high.
Accredited for Use with Food
Components made from unfilled PTFE are physiologically inert. They are therefore safe for use in medical devices and food processing installations. The relevant international approvals/compliance certificates in accordance with FDA, EU, and BfR regulations have been obtained. FDA declarations of conformity also exist for fiberglass compounds as well as some thermoplastic fillers. In addition, toxicity tests have been carried out successfully.
