Sensitivity to emissions in automotive interiors has been a topic since the early 1980s. This was in particular caused by the formation of undesired condensation on the inside of windshields of new vehicles. As a result, the focus of material developers was initially on achieving specific fogging values. The requirements for interior components have been extended and have become more sophisticated over the years. Various analytical test standards were gradually developed to ensure compliance with emission standards. Odour has become a more critical issue for both automotive OEMs and consumers.

With its highly abrasion-resistant Raku Tool WB-1258 foundry board, Rampf is offering an alternative to face cast pattern plates and highpriced metals for a wide range of foundry modeling applications. Thanks to its very good abrasion resistance, more than 100,000 replications can be produced with the PU board. This was previously possible only by using either liquid systems with complex manufacturing processes with higher costs or high-priced metals like aluminium, said the company.

Graphene nanotubes can improve abrasion resistance of a rubber stator by 20 % and increase tensile modulus by 30 %.(Source: Ocsial)

One of the largest Chinese producers of PDM drilling tools, Orient Energy & Technology Ltd., has found that graphene nanotubes improve abrasion resistance of the rubber stator by 20 % and increase tensile modulus by 30 %, resulting in a shortened drilling cycle, reduced energy consumption and less environmental pollution from the drilling equipment. Orient Energy & Technology has completed laboratory testing of nitrile butadiene rubber (NBR) containing Tuball graphene nanotubes supplied by Ocsial. According to Ocsial just 1.7 wt% of graphene nanotube concentrate introduced into NBR was found to increase the tensile modulus by 30 %.
