Laboratory PTFE Products

PTFE (Polytetrafluoroethylene) items represent a high-quality solution for numerous laboratory applications due to their exceptional chemical, electrical, and thermal properties. This high molecular weight polymer is characterised by an extremely low coefficient of friction and high resistance to the most aggressive reagents and solvents, ensuring optimal performance in corrosive and ultra-pure environments.

Features and Materials

PTFE stands out for its practically total chemical inertness, making it resistant to a wide range of acids, alkalis, and solvents, without contaminating sensitive materials. The thermal stability ranges from -200°C to +300°C, with thermal degradation occurring only beyond +400°C. The electrical properties are excellent, featuring high electrical resistance, low dielectric constant, and low dielectric loss factor. Additionally, PTFE exhibits exceptional non-stick characteristics, thanks to its self-lubricating nature, along with toughness and flexibility, even at low temperatures.
