Flat gaskets are cut from moulded sheet using state of the art reciprocation knife cutting technology or rule dies. Larger gaskets can be cut from moulded or fabricated picture frames. This option has the advantage of saving material and allows larger gaskets to be produced most efficiently. Fabricated frames use either extruded or moulded flat section that is joined by vulcanizing the polymer. We use the same conductive polymer compound to vulcanize the joints ensuring complete electrical conductivity is maintained across the joint. This process has allowed Kemtron to produce gaskets up to 2 metres long, with the same mechanical and electrical integrity as found in a single part gasket cut from sheet. This method of manufacture often offers cost savings over cutting from sheet which creates significant loss of waste material. Our in-house production facilities are suitable for prototype, short and medium production runs, as well as commercial quantities. Performance Kemtron’s Electrically Conductive Silicone Elastomer materials tests are performed in house and by external laboratories all using calibrated equipment, testing to the standard specified in MIL-DTL-83528. Kemtron offer the performance data and methods of testing to MIL-DTL-83528 for comparison only.
