GEHR PEEK® can be used at very high temperatures (about +260 °C) and it shows an extraordinary mechanical strength, toughness, hardness, flexural strength, torsional strength. PEEK exhibits excellent chemical resistance, very good dielectric properties up to +260 °C and a very good resistance to all kinds of radiation (even ultraviolet rays only lead to a slight yellow discolouration). PEEK is self-extinguishing properties according to UL 94.

Technical Details & Test Data

Fire-fighting Measures

Suitable extinguishing agents

Water, foam, dry chemical, carbon dioxide (CO2).

Potential combustion products

Carbon dioxide (CO2), carbon monoxide (CO). Formation of further decomposition and oxidation products depend upon the fire conditions. Under special fire conditions traces of other toxic substances are possible.

Special protective equipment

Wear a self-contained breathing apparatus. If exposed to combustion fumes bring the victim into fresh air.

Further information

Dispose of fire debris and contaminated extinguishing water in accordance with official regulations..

Safety & Health

Safety Measures

The general industrial safety measures should be considered. A thermal damage during machining should be avoided.

Storage & Handling

Machining

The product can be machined with standard machinery and tools. Before machining the product should be stored at room temperature 24 h. Evacuate swarf to prevent slipping or tripping. Observe the maximum allowable concentration of dust and formaldehyd levels on the working area which apply in your country. Wear safety goggles during machining. General dust limit value: Respirable dust (6 mg/m3); Inhalable dust (10 mg/m3 ).

Storage

The products shall be stored indoor to keep away from any source of degradation such as sunlight, UV-jets, ionizing radiation, chemicals.
