Bayer MaterialScience L.L.C. released its two-component polyurethane systems, which the company said can withstand harsh environments and offer durability and high functionality.
The company said the systems are becoming an attractive option for protecting pipes where challenging conditions often include field application, high service temperatures, high salt load and wet soil.
The building blocks of rigid polyurethanes were screened and the resulting raw material property profile was modified to fulfill the requirements for these applications. The company said the systems also provide the fast processing required for application in factories.

Rhein Chemie Rheinau GmbH introduced Rhenowave, a concept for controlling the quality of rubber compounds. The compounds are analyzed during extrusion in a pulse transmission process with the help of ultrasound waves.
The company said nanoscale fillers, such as carbon black and silica, have particularly good damping properties for soundwaves in the range of 1 MHz to 20 MHz, so the filler content can be determined with a precision of up to 1 phr. Unlike other analytical methods that use electromagnetic waves, carbon black does not disturb this process, the company said. As a result, even black compounds can be volumetrically analyzed.
The distribution of Rhenogram AP can be monitored by using a marker with a high density, such as zinc oxide. Rhein Chemie said Rhenogran AP products are customer-specific additive packages made from crosslinking chemicals and are polymer-bound, dust-free and easily dispersible.
Rhenowave can be used alone or in combination with Rhenogran AP, the company said, and can be used in a production scale of 1,000 kg/h. Rhenowave is non-destructive.

APS Elastomers released its low-cost polyester-based TPU for less demanding applications, such as shoe heels and roller wheel applications.
APS said the injection molded TPU is available in hardness range of Shore A 80 to Shore D 64 and exhibits good mechanical and processability properties.

Styron L.L.C. had added two additions to its Sprintan rubber range, the Sprintan SLR 3402 and SLR 4502, next generation solutions adjusted for improved low-temperature performance.
Styron said the Sprintan SLR 3402 and SLR 4502 offer the combined benefits found in existing Sprintan grades, including low rolling resistance, reduced stiffness at low temperatures boosting snow grip potential in winter tread application. Both solutions can be blended with other polymers, offering greater flexibility.
For the ultra high performance pass car tread, Styron said the Sprintan SLR 4502 and 3402 can be applied to partially replace high-Tg SSBR and BR. Both grades bring additional reduction in rolling resistance due to their functionalization technology that is effective with silica as well as with carbon black fillers, it said.
Styron's Sprintan rubber portfolio offers high performance solutions to fit specific tire industry needs, including rubber grades with enhanced wet grip and wear performance, as well as grades that provide a good balance between traction and rolling resistance.
