DuPont polyolefin processing aids receive K 2007 launch

A

t K 2007, DuPont Performance Elastomers (DPE) will extend its proprietary Z Technology™ range for plastics masterbatchers and producers of extruded sheet, films and other thin-walled structures with the launch of Viton® FreeFlow™ Z110 and Z210 process aids for polyolefins. The company will also use the show to celebrate the commercialization of Viton A, which led to the creation of the fluoroelastomers industry.

According to DPE, the two new fluoroelastomer process aids will complement the successful Viton FreeFlow™ Z100 and Z200 products by eliminating melt fracture, and by reducing extrusion pressure, amperage, torque and die build-up in moderate mixing situations. Anticipated application areas include solution LLDPE, masterbatches with more than 2% process aid, blown film using 1 to 3 MI LLDPE, and extrusion under low shear conditions. The Z100 and Z200 products were launched five years ago [ADPO, November 2002]. Other DuPont businesses will also present innovations at the K show.

Sachtleben reveals new antiaging concept for polymers

S

achtleben Chemie GmbH of Duisberg, Germany, is to unveil innovative anti-aging additives for special polymer applications at the K 2007 show.

The company has taken synthetically precipitated zinc sulphide from its proven Sachtolith product family and modified it in such a way that it can significantly extend the time before polypropylene and polyethylene cables become brittle or break. It is claimed that the new, nanoscale product can prolong the life of cable insulation, pump housings, washing

machine hoses and water pipes by up to 100%, with a consequent increase in safety and reduction in repair costs. Cable and hose products that last longer also have a lower environmental impact because they are discarded less frequently, says Sachtleben. Use of the new inorganic particulate additive can partially and cost effectively replace the organic thermal stabilizers, antioxidants and metal deactivators previously used exclusively for the protection of polyolefin products against material fatigue, the company says. In fact, using the new inorganic additive in conjunction with organic stabilizers has been found to have a synergistic effect: according to Sachtleben plastics expert Dr Petra Fritzen, the interaction of these two product types ‘significantly increases the durability characteristics of polymers’. And, unlike the regular-scale Sachtolith product, which can achieve around 10% longer life for cables and hoses but continues to function as a white pigment, the new, nanoscale functional additives are transparent and therefore have no influence on polymer colour. Following successful laboratory testing of the thermal stability of the new generation of nanofunctional additives, these are now undergoing industrial-scale trials with selected customers, reports Stéphane David, head of Sachtleben’s Business Unit Plastics. ‘We then intend – by early 2008 at the latest – to offer this totally new line of products to all compounders and manufacturers,’ David says. Customer interest is already significant, he says, and the K show will provide an opportunity to discuss technical details and support with interested parties, and to work out individual customer benefits and the associated competitive advantages.
