A snapshot of bitumen-based waterproofing

January 22, 2018 11:25 AM

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.

Global TPE markets

January 15, 2018 9:30 AM

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.

TPE tubing for drinking water and medical use

January 5, 2018 1:05 PM

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.

Why hot melts do not stick to cold surfaces

December 25, 2017 1:35 PM

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).
