Mecaplast and Inno-Comp show Hyperform benefits in PP

French automotive compo- nent producer Mecaplast has made significant weight reductions in injection moulded TPO parts by partially replacing talc filler with Milliken’s Hyperform HPR-803i reinforcing agent. Inno-Comp of Hungary has supplied the company with a TPO compound that contains a mix of talc and Hyperform HPR-803i to give a total additive content of around 10% by weight. Mecaplast has used this material to mould prototype B-pillar covers which are normally made using a 20% talc-filled TPO. The prototype parts weigh 524 g, which is 7% less than the commercial parts. The compound with Hyperform has a density of 0.98 g/cm3 compared to 1.04 g/cm3 20% talc-filled TPO with

for a THERMAL CONDUCTIVITY PolyOne targets LED applications

PolyOne has launched new Therma-Tech thermally conductive grades for light- emitting diode (LED) lighting applications. The polymer compounds are designed to replace metal heat sinks, enabling parts consolidation and providing better management of hot spots. The company says that these properties

result in longer LED lifetimes, reduced weight, lower manu- facturing costs and improved in-service performance. The new grades were launched at the recent Chinaplas exhibition in

Shanghai. “China is the leading producer of LED lamps, while Europe is leading the demand, therefore we are launching our new Therma-Tech thermally conductive plastics for LED lighting applications first in these two regions,” said Eng Guan Soh, general manger, PolyOne Engineered Materials Asia.

similar mechanical properties. Nathalie Samson-Maguet,

Mecaplast’s research and innovation manager, says that the final product costs are the same: Hyperform HPR-803i costs more than talc, but this is cancelled out by the reduced total material requirement. She adds that the TPO

compound could also be used to reduce the weight of larger parts such as C-pillars and sill panels. For a typical C-seg- ment car, use of compounds containing Hyperform HPR-803i in these parts alone could yield a total weight saving of at least 225 g, according to Samson-Maguet. In addition to reducing part

weight, Hyperform HPR-803i improves scratch resistance, which is important as the B-pillar covers are normally installed in the car unpainted. Mecaplast is aiming to go


PCC extends FlamaSol FR technology for use in PE

Plastics Color Corporation (PCC) has expanded the use of its FlamaSol FR propri- etary flame retardant technology to polyethylene formulations. The additive masterbatch contains no decaBDE and was developed as an alternative option for customers preparing for the planned phase out of this brominated product. PCC initially developed the

into production with TPO parts reinforced with Hyperform HPR-803i within the next two years. The company makes parts for several major car companies, including BMW, Citroen, GM, Peugeot, Renault, Toyota, and VW. ❙

new additive for PP applica- tions and it plans to further extend its use to PMMA, PS, PVC and other thermoplas- tics. It is suitable for injection moulding, blow moulding and extrusion processes. PCC says that FlamaSol

FR is ideal for use in construction applications, such as electrical conduit plus junction and switch boxes. It can also be applied in warehouse products, including shelving and pallets, and in personal electronic equipment such as computers, printers and televisions. FlamaSol FR surpasses

the testing standards of UL 94 and ANSI 4996 for plastic pallets and performs better than PCC’s previous flame retardant system, according to the company. It is available in white, black and natural master- batches as well as in custom colour formulations. ❙
