product update | Materials COMPOSITES RTP targets metals with carbon fibre
US-based compounder RTP Company has introduced a new line of high performance materials based on carbon fibre reinforced PEEK, PPA, PPS, and PEI thermoplastics. Combining the high
mechanical performance and low density of carbon fibre with the good thermal and chemical resistance of high temperature resins allows these injection mouldable thermoplastic

Thermally conductive LED grades
Lehman & Voss has developed a range of thermally conductive polymer compounds targeted at applications in LED lamp housings and components. The new materials,
which are based on PET and PA6, are characterised by thermal conductivities rang- ing from 0.6 to 1.5 W/mK. The grades are electrically insulating and provide tensile strength up to 55MPa and impact strength to 29 kJ/m2
. They also offer
UL94 V-0 flame resistance. According to Lehman &
Voss, the materials meet LED market performance requirements while providing the good process- ing characteristics needed for complex geometries and thin wall sections. ❙

compounds to close the performance gap between plastics and metals, says RTP. Ultra Performance
Structural Compounds are available with carbon fibre reinforcement loadings from 20-40%. The company sees the new grades finding applica- tions in energy, industrial, aerospace, automotive, and medical markets that would have previously specified

Elastocon launches snap-fit TPE line
Elastocon 9050 is a new grade of TPE from Elastocon of the US targeted at applications requiring a mechanical snap-fit, such as automotive trim rings or console shifts. The new 50 Shore D TPE is formulated to
provide a good mechanical lock in a range of applications where parts need to be removed for service. The company says the materials also offer good impact performance at low temperatures. Two grades are available: 9050BX is a black
product while 9050X is a natural version for custom colouring. Both offer a dirt resistant, non-gummy surface that will retain an as-new appearance over extended periods of operation. ❙

COCs Topas adds moulding option
Topas Advanced Polymers has expanded its line of cyclic olefin copolymer (COC) resins for injection moulding with a new grade – Topas 5013L-10 – with internal mould release. “The boost in processability
from the internal mould release has made this new

grade the go-to choice for components with high aspect ratios, precision details, and other moulding challenges,” says Timothy Kneale, president of TOPAS Advanced Polymers in the US. The transparent polymer is characterised by high flow with
no loss of material strength and optical characteristics. Its low melt viscosity allows production of ultrathin light guide plates used in displays in mobile devices such as tablets and smartphones, according to the company. ❙

aluminium, zinc, and magne- sium metals. “With higher strength and
stiffness values along with improved impact and fatigue resistance, these materials provide across-the-board performance improvements that will give product design- ers added confidence when specifying,” says Matt Torosian, High Temperature Product Manager at RTP.
“That translates into
weight reduction opportuni- ties, having the ability to overcome design limitations through part consolidation and optimisation, and to reduce manufacturing cost and shorten production time by obtaining net shape parts through a one-step injection moulding process,” says Torosian. ❙
