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...

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...

Improving the mechanical Properties of Tyre Tread Compounds with different Types of Carbon Fibers

The properties of unsized and coated with different sizing material carbon fiber (CF) reinforced tyre compounds were examined. Unsized CF and CFs which were sized with polyurethane-, epoxy- and phenoxy-sizing were selected. A blend of SBR and BR was used as matrix. The tyre compounds were prepared by using open two-roll mill. The effects of […] more...

Rolling Resistance of TBR Tires

NR-Silica-Masterbatches – The easy Processing Way to High Quality Compounds

Growing requirements of higher fuel economy increase the pressure on producers of TBR tires to use silica as a filler in Natural Rubber compounds. Currently this seems to be the silver bullet to further reduce Rolling Resistance without compromise in Skid and Wear. High quality Natural Rubber compounds filled with Silica and Silane in high […] 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...

PH-sensitive Absorbent: Anionic Polyacryamide/Cassava Starch Hydrogels containing Natural Rubber for Lead and Magnesium removal from aqueous Solution

The novel absorbent from polyacrylamide (PAM), cassava starch and natural rubber (NR) by microwave assistance were produced to remove lead ion and magnesium ion in aqueous solution. The absorption of Mg2+ and Pb2+ of the novel absorbent increases as function of sample weight due to high site group or carboxylic group of absorbent. The highest […] more...

Simulation of Tearing Energy

Prediction of Energy Release Rate in Anti-Plane Shear State (Mode III) for unfilled Elastomers

The analytical energy release rate of a cracked body in anti-plane shear state is determined by means of using the solution of the boundary value problem. The analytical calculations in the non-linear fracture mechanics are based on non-linear hyperelastic material behaviour. The Ogden model is considered for the numerical calculation of the J-integral and the […] more...

Influence of thermal Aging on mechanical and tribological Properties of Roller Compounds based on EPDM

Due to mechanical, thermal and chemical impacts, elastomer covered rollers used in plastic-sheets- and printing industry show strong aging and wear. Therefore, elastomer rollers need to be exchanged and newly grinded or covered quite often. This study focuses on the influence of thermal aging on mechanical and tribological properties of roller compounds based on EPDM, […] more...
