Handling: Fluteck™ K300 PEEK can be stored for a long period of life and is exceptionally resistant to aging and weather conditions up to 10 years. Specific aging tests carried out on sample exposed to aging and atmospheric conditions, showed no changes in weight and volume. The products shall be stored indoors in a normal environment ( air at 10-30°C /50-86° F and 30-70 % RH ) and kept away from any source of degradation such as sunlight, UV lamps, chemicals, ionizing radiation, flames, etc. Dimensional change (camber, warpage, shrinkage) of the products as well as slight color shifts of the external surface can occur with time. The letter does generally not pose a problem in case of semi-finished products since the surface-layer is mostly removed anyway upon machining them into finished parts. During machining of the semi-finished products, evacuate swarf to prevent slipping or tripping hazard and observe the maximum allowable concentration of dust levels on the workplace which apply in your county. Wear safety goggles during machining.
