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 %.

For sealing materials in contact with gases such as hydrogen, a consideration of gas permeability is of elementary importance for the assessment of safety, functionality and reliability. The aim of the presented study is to give an overview of the permeation behavior of thermoplastic vulcanizates (TPV) and ethylene-propylenediene rubber (EPDM) towards hydrogen under consideration of processing influences. A comparison of TPV and EPDM shows a differentiated permeation behavior.

Serinol and serinol derivatives are used in place of diphenyl guanidine as secondary accelerators for the vulcanization of compounds based on diene elastomers and silica as the filler. Kinetics of crosslinking are investigated and confirmed by performing vulcanization of an NR based compound in the absence of any filler. Serinol can be obtained glycerol transformed, by means of sustainable technologies into molecules suitable for the rubber world.

In addition to strand pelletizing, ips Intelligent Pelletizing Solutions GmbH & Co. KG has also established a solid standing in the market with underwater pelletizing systems. Since the launch of this type of system in 2016, ips has already sold some of ips-UWG 75 S underwater pelletizing systems. Now the first ips-UWG 120 S system for throughputs of up to 2,500 kg/h is to be commissioned at the premises of an extrusion profile producer in Italy. The company manufactures most of the materials required for its production internally. Among other things, these include the appropriate compound for the production of pipework systems. In future, this will be manufactured using an unterwater pelletizing system ips-UWG 120 S.

In this work a new laboratory test equipment is presented, that allows for the definition of suitable load conditions (force, rotational speed, impact incidence). The Instrumented Chip & Cut Analyzer (ICCA) collects all relevant data during the test. Using a mathematical algorithm, realistic and reliable answers on CC behaviour of the rubber are derived from the measurements.
