LEDs are relatively cold light sources, but LED
headlamps can still generate considerable amounts of heat. SABIC already has an extensive portfolio of XHT (extra high temperature) grades of Lexan, with heat deflection temperatures (HDTs) of up to 183°C (under a load of 0.45 MPa), but it says many high-heat polycarbonates still have problems with flow (for example, weaknesses are knit lines or limited flowability in comparison to regular PC) and these materials cost more than ‘standard’ PC. The new grades, Lexan XHT1171, XHT2171 and XHT3171, address this issue. SABIC says they provide particularly high flow for high temperature PC resins. They can be considered as drop-in alternatives to standard PC. A recent moulding study carried out by SABIC
indicated that a bezel moulded in Lexan XHT2171, could weigh 37% less than a bezel in a rival PBT material, thanks to possible reductions in wall thickness and the lower density. It has the potential to enable cost savings of up to 40% per bezel, by avoiding the use of complex tools, potentially enabling faster moulding and part integration as well as reducing weight.

The conference will provide valuable insights into the latest developments in fittings and joints, which play a critical role in the integrity and performance of plastic piping systems. Expert speakers will discuss trends in materials, production technologies, designs and applications, as well as addressing the latest advances in testing and certification. Papers are invited on all topics related to plastic pipe fittings and joints including (but not exclusively): • Operational experience with plastic fittings and pipe joining • Fitting design and selection • Fitting manufacturing and materials • Welding methods and equipment •
Adhesives
• Seals •
Joint integrity, testing and standards
• Cost-effectiveness of joining methods •
Industry trends and markets worldwide
