It is advisable to cover the heated tools with Polytetrafluorethylene. Polytetrafluorethylene is recommended for the heater. Cementing Oletex can be cemented to itself or to other materials. This characteristic is advantageous when contact adhesives are used. Oletex should be printed by screen or gravure printing techniques.
Band knives are also suitable.
Circular saws are suitable for straight cuts. The cut surfaces will be clean if, during the cutting operation, the teeth of the blade project only slightly above the foam. Band saws are recommended for thicker foam slabs and also for curved cuts from 0.6 to 1.0 in. The saw blades should be about 15 to 25 mm wide and 0.03 to 0.04 in thick, as normally used in the fabrication of foamed plastics. Band knives are usually used for this operation.
