PREMIX INTRODUCES UNIQUE NEW CONDUCTIVE COMPOUNDS FOR ESD AND EMI APPLICATIONS
25 November 2006 - Premix Oy

Premix has recently extended its range of conductive compounds to cover also novel Inherently dissipative polymer compounds for use in clean room applications meeting the new ESD standards. The new PRE-ELEC ESD grades are washable, reusable, recyclable and colourable with surface resistance values permanently between 10e8 to 10e9 ohms. Since they do not contain carbon black, metals or antistatic additives, they are non-sloughing, low outgassing and low extractable plastics. The PRE-ELEC family of ESD compounds is currently available in PP, PE, ABS, PETG and PC/ABS. They can be processed with standard extrusion and injection moulding equipment.

Since the PRE-ELEC ESD compounds exhibit same mechanical properties as natural plastics, finished parts can easily be manufactured with a good price-performance ratio through downgauging.

They also meet BgVV’s requirements on cleanliness and can be used in contact with foodstuff. This opens up new applications for example in the pharmaceutical industry and agriculture.

The new PRESEAL TPE compounds are unique thermoplastic elastomers offering extremely high conductivity. These materials have been developed mainly for the electronics industry to meet the requirements in EMI shielding gaskets. The major advantage of these materials over the currently dominating silicon gaskets is the easy production by injection moulding or extrusion. Typical properties of the PRESEAL grades are volume resistivity 10e-2 ohm cm and 100 dB in shielding effectiveness. These values together with 65 to 75 Shore A hardness and <35% Compression set at 85°C make the products ideal for demanding gasket applications.
