GEHR PEEK® 30CF

1 of 7 products in this brand
GEHR PEEK® 30CF is a variant of PEEK modified with 30 % carbon fibers. As with the glass-fiber reinforced type, the surface hardness and heat deflection temperature are also significantly increased compared to the already high values of the unreinforced standard type. This material owes its significantly increased dimensional stability to its extremely low coefficient of linear expansion. The electrical properties are influenced by the high proportion of carbon fibers and must be taken into account in the relevant applications.

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.
