Crack Propagation of Vulcanized Rubber

Ozone-Resistivity of Isoprene Rubber mixed with a Wax as an Antiozonant at below Freezing

Effect of wax on the ozone resistance of vulcanized natural rubber (NR) and vulcanized isoprene rubber (IR) was investigated by observing crack propagation of the vulcanized rubbers at 40°C and -30°C under 50 pphm ozone atmosphere. The ozone exposure test for the vulcanized rubbers was performed, after the wax bloomed at 40°C under a strain of 0.2. more...

Self-sealing tires make spare wheels redundant .(Bildquelle: Lanxess)

Arlanxeo at Tire Technolgy Expo 2018

Rubber Compound for self-sealing Tires

Arlanxeo has developed a rubber compound that can be used in the future to seal tires. This solution for so-called self-sealing tires replaces the spare wheel and also presents an alternative to a repair kit or run-flat tire. An appropriate rubber compound, which is applied on the interior of the vehicle tire, enables holes occurring in the tire to be automatically sealed, so the driver can continue driving. Arlanxeo is presenting the development at Tire Technolgy Expo 2018, Booth 4014. more...

Study of rheological, physico-mechanical and morphological Properties of Nitrile Butadiene Rubber loaded with Organo Bentonite

The rheometric characteristics and physico-mechanical properties of bentonite (Bt)/ and modified bentonite (organo-Bt)/acrylonitrile-butadiene rubber (NBR) were investigated. Scanning electron microscopy (SEM) showed that the rubber chains may be confined within the interparticle space and the Bt particles presented a physical dispersion in NBR matrix. Bt was modified with tetra butyl phosphonium bromide (TBP) in order […] more...

Keltan Eco – Technical and historical Summary

Green EPDM Compounds

Keltan® Eco is the world’s first commercial EP(D)M rubber partly produced from bio-based feedstock. The ethylene used for this rubber is produced from ethanol, derived from sugar cane. To increase the sustainability of EPDM rubber products the potential of greener alternatives for traditional plasticiser oils and fillers have been explored. A variety of (trans-esterified) natural […] more...

Vulcanization of silica-filled car tread compounds

Rhenocure DR – A New Secondary Accelerator for Rubber

Diphenyl guanidine (DPG) is the most used secondary accelerator in silica filled passenger car tread compounds Beside its function as secondary accelerator DPG acts in this application also as a processing aid. A problem accompanied with DPG is that it releases carcinogenic aniline during the vulcanization process. Several solutions are available to replace DPG like […] more...

Historical and technical Summary of Keltan Developments

Defining EPDM for the past and the next 50 years

In 1967 the first Keltan bale was produced in Geleen, the Netherlands. During the following five decades Keltan has realized continuous improvements regarding catalysis, process, product and application technology. Starting with the introduction of DCPD as diene and ending within the introduction of Keltan ACE catalysis for more sustainable production and the exploration of Eco bio-based EPDMs. Innovation combined with high EPDM quality, the broad portfolio, the technical service and the global presence has earned respect in the the rubber processing industry. more...

High quality in Multi-component injection molding

Hard/soft combinations based on adhesion-modified TPV and polyamide

This paper is focused on a new adhesion-modified TPE-V series called Alfater XL 4PA0010 for high quality PA-based hard/soft combinations. These adhesion-modified TPE-V grades offer good bonding to a broad range of PA6 and PA66 including non-reinforced, glass fiber reinforced, and impact-modified PA. They are suitable for conventional 2-shot injection molding as well as for cold insert molding. Influences on the bonding, like the injection molding conditions or additives in the compounds or furthermore high moisture contents of PA have been examined. more...
