One of the most widely used industrial coatings is epoxy surface coatings, which provides excel-lent adhesion and wear resistance when applied to metal surfaces. The erosion behavior of epoxy/ coatings by solid particles impact was investigated.

In this study, it was intended to heal mechanical and fracture behavior properties of recycled poly(ethylene terephthalate) (PET) by using of polycarbonate (PC) as blend component and epoxy-based chain extender (Joncryl) as compatibilizer. 

In the present work; sunflower husk, peanut shell powder are used as natural fillers besides sesame and castor oils to improve the tribological performance of basalt fiber reinforced epoxy composites. Epoxy matrix reinforced with 30% vol. basalt chopped fiber for purpose of enhancing mechanical strength, hardness, and stiffness of composites.

The effects of co-agent (TAIC) and ionizing radiation on the dynamic mechanical properties of phenyl-vinyl-methyl-polysiloxane (PVMQ), cured thermally with peroxide, tested on Dynamic Mechanical Yerzley Oscillograph (DMYO V) under dynamic compression and static hysteresis.

In the present work, experiments revealed that epoxy composites filed by recycled rubber particles and paraffin oil showed improvement in friction coefficient and wear. Composites free of oil showed the highest values of friction coefficient when they contained 40 wt. % rubber.

Ressourcenschonung, Energieeffizienz und Prozessoptimierung sind gefragter denn je – bei gleichbleibender Performance. Um zusätzliche Potenziale von PMMA zu erschließen, haben sich zwei Firmen zusammengetan, die den Werkstoff verstehen und weiterentwickeln wollen.

Ovale Lüftungsrohre aus Kunststoff werden in der Bau- und Haustechnik zunehmend eingesetzt. Die Wellrohre benötigen weniger Platz bei gleicher Luftführung. Klingt plausibel. Doch wie einfach ist es in die Produktion von ovalen Wellrohren einzusteigen? Der Fachartikel zeigt mögliche Fallstricke auf.

Polyurethane foams (PUF) are generally flammable, so they are limited in some applications due to strict fire safety requirements. In this study, three distinct industrial benchmark polyurethane foams containing synergistic combinations of expandable graphite (EG) and phosphorous flame retardants (P-FR) were investigated one by one for their fire performance and smoke behavior.

The effect of the pre-aging at 250o C before the measurement of thermogravimetry of tetrafluoroethylene-propylene elastomer was studied. The longer the pre-aging time, the more the linearity of the analyzed line with reference to ISO 11358-2 was improved.

It was tried to improve the resilience of TPE against heat and pressure. Considering well-known results from rubber, the way was to reinforce TPE with short fibers. Compounding processes without any difficulties are possible with fiber granules.
