Dymax said these resins are formulated with high-visibility black (GA-140-B) and green (GA-140-G) color enabling easy confirmation of correct placement of the gasket. These products demonstrate excellent bond strength to metals, glass and most plastics. They are typically used in sealing applications on fuel cell plates and stacks, automotive door handles and side-mirror assemblies, and appliance housings, as well as in critical electronic assembly and device applications. 

 

These materials resist high-temperature and high-moisture environments, Dymax said, while maintaining superior adhesion and flexibility. They exhibit low shrinkage, resulting in reduced stress on the fuel cell plate, stack housing, appliance housing, or electronic assembly. 

 

 

Qualitest International Inc. has launched Moving Die Rheometer, a cost-saving and reliable device that effectively measures changes in the stiffness of rubber samples.

 

Qualitest said the rheometer features custom-designed MDR software, developed to provide an intuitive, user-friendly and customizable interface that can be configured for a wide variety of tests, the company said. This software also includes an automatic data backup system to protect test results. 

 

Moving Die Rheometer offers both sealed die and un-sealed die type configurations to suit a wide range of needs. 

 

Qualitest also has introduced its DigiTest II Automatic Motorized Hardness Testing System, a Shore/IRHD hardness tester with a modular design. 

 

Qualitest's DigiTest II provides the accurate results while remaining cost effective and adaptable, Quali-test said, because of its extensive range of accessories and its automatic testing procedure. 

 

 

ExxonMobil Chemical has unveiled Vistamaxx PBE Part Sample Library, a virtual library that allows customers to search and discover a range of commercial applications in which Vistamaxx propylene-based elastomer is used to add value in different ways.  

 

The potential benefits of Vistamaxx PBE in application include: new levels of performance, low total cost solutions and simplified processing; along with help to deliver more sustainable solutions for polypropylene modification and compounding applications because its low density relative to many other polymers can allow lightweight products to be designed. 

 

ExxonMobil said when Vistamaxx PBE is used in a polyolefin blend, it can contribute to less overall waste in the manufacturing process, as any scrap produced during processing can be recycled.
