taping, armouring & sheathing of cables

SAMP and DS&M started a new partnership SAMP, manufacturer of extrusion cable lines, and DS&M, well-known in the field of dosage and control systems production, have together developed a new technology which enhances the performance of the whole extrusion process and is believed to be much cheaper than traditional production lines. After extensive experimentation, research and development, SAMP and DS&M have created a new extrusion module suitable for the vast majority of granulated material. The group is called “Multiflex 25 Extrusion Module” and is made of a 25-diameter extruder integrated with a dosage and mixing unit of polymers and silane, conveniently developed to improve the homogenisation among solid and liquid components before plasticising.

New flame retardant compound for use in high-heat environments Dow Wire & Cable has introduced Unigard™ RE HFDA-1492, a reduced-emissions flame retardant compound for use in wires and cables needed in high-heat environments, such as those found in automotive engines and appliances. Capable of tolerating temperatures of up to 125°C, the new compound also offers important processing, environmental tolerance and ease of installation benefits while meeting industry and end-use market specifications.

Unigard RE HFDA-1492 is a colourable, peroxide-crosslinkable, polyethylene copolymer insulation compound. It is approximately 4% lighter than traditional materials used in automotive wire and cable applications and delivers more output per pound, offering system cost benefits as a result. Designed to enable the manufacture of cables that are more flexible with lighter weight and improved colour retention, HDFA-1492 also has a low specific gravity of 1.35 to help reduce the consumption of compound per cable length. Tests with HFDA-1492 have also shown a 20-50% improvement in line speeds on Dow customers’ existing equipment, compared to a commercial automotive compound. A broad processing window, from 105°C to 135°C, also supports potentially higher line rates. Unigard RE HDFA-1492 additionally addresses important environmental and North American legislative requirements by providing PVC-like performance with LS0H (low smoke zero-halogen) advantages at a competitive cost.

Excellent results obtained for over a year on a pilot production line created the basis for a technical and commercial partnership between SAMP and DS&M, who recently signed a specific agreement. SAMP and DS&M presented their new project during the wire 2008 exhibition in Düsseldorf. SAMP – Italy Fax : +39 051 356 750

Semi-conductive/non-conductive water blocking tape Semi-conductivewater blocking tapes are used for water blocking between power cable components. Its swelling characteristic is believed to be superior to traditional water blocking tape due to the lack of a covering fabric. It offers a replacement for traditional semi-conductive tapewith no causticity. Non-conductive water blocking tapes are used for water blocking between the components of optical fibre cable,
