For more than two millennia, asphalt bitumen has been used as a key raw component in the construction industry. Long before the first oil refinery produced its first barrel of asphalt, builders and waterproofers used natural sources of asphalt for various applications. References to the use of asphalt are scattered throughout antiquity—early references in texts such as the Bible include the use of pitch or bitumen in the building of the Tower of Babel.

S. S. Banerjee, A. K. Bhowmick This paper reviews different types of high-temperature thermoplastic elastomers (TPE). The preparation, structure, and functional properties of these materials are discussed briefly. Strategies to further improve the high-temperature performance of these materials are presented herein. A synopsis of the applications of these high-performance materials in the automotive industry is reported, pointing out the gaps to motivate potential research in this field.

WASHINGTON (January 3, 2018) – Data collected and tabulated by the American Chemistry Council shows that growth in global chemistry during November was buoyed by a synchronized up-swing in the global economy.

As portions of the TPE market space mature, some TPEs approach commodity status in which there is little price or quality differentiation between compounders for comparable grades. A commodity trap emerges and escaping it becomes a key strategic objective. Globalization is affecting TPE market structure, acquisitions and pricing. Experience in Asian markets has taught compounders that price/quality can be tailored to different levels as market segments dictate.

hermoplastic vulcanizates (TPV) have been widely used in many industrial applications, particularly auto motive weather seal applications.

Among film types, epoxy films are expected to witness a higher growth rate during the forecasted period.

Since their first appearance in the market, thermoplastic elastomers (TPE) have mainly been utilized in injection molding and have experienced some difficulties gaining ground in the extrusion world, as this has traditionally been dominated by vulcanized rubber on the one hand and plasticized PVC on the other. However, in recent years there has been a strong tendency to reconsider TPEs as suitable candidates for a number of extrusion applications – a trend favored mainly in the fields of drinking water and medicine as a result of more stringent hygienic requirements.

Thermoplastic elastomeric seal are thermoplastic processing, easy and quick without curing, processing and recycling can be repeated green products; it also has the function and nature of thermoset rubber (soft, flexible, tactile nature) .

According to a recent publication by Transparency Market Research (TMR), the global thermoplastic polyurethane (TPU) industry is expected to grow at a 5.5% CAGR during the period of 2013-2018, reaching US$1,746.9 million by the end of the forecast period. The global TPU market stood at US$987.2 million in 2010.The research report, titled “Thermoplastic Polyurethane (TPU) Market – Global Industry Analysis, Market Size, Share, Trends, Analysis, Growth And Forecast, 2012 – 2018”, states that the global market for TPU is stimulated by the extensive development of the global footwear and automotive industries.

D. F. Treffer, J. G. Khinast Many industrial polymer processing operations (e.g., extrusion, injection molding, etc.) include solid-to-liquid or liquid-to-solid phase changes at non-isothermal interfaces. Stickiness (tack) can occur depending on the process conditions. However, prediction of tack formation is not trivial. This work presents a hypothesis for tack formation between molten polymers and solids under non-isothermal conditions. Our hypothesis states that strong adhesion requires wetting (and thus surface creation) at the interface upon contact and, consequently, contact temperatures above the polymer’s solidification point. Lower contact temperatures result in a solid-solid interface with negligible adhesion. It was suggested that the contact temperature determines the existence or non-existence of surface sticking. The hypothesis was supported by non-isothermal tack experiments, which show that the change from stickiness to non-stickiness is surprisingly pronounced with changing surface temperature of the solid material. From a practical perspective, the work may be useful both for professionals (e.g., designing new processing equipment and performing process troubleshooting) and home users (e.g., working with hot melt glue or 3d printers).
