FEPM type fluoroelastomers are shown to improve the performance of high voltage automotive charging cables.
Mixing
Effect of accelerator mixing ratio on curing characteristics of EPDM gasket materials
In a four-person household, the washing machine is in operation about one and a half hours a day. On average, it washes, rinses and spins about 250 times a year, cleaning some 1,000 kilograms of dirty laundry, an amount that is increasing all the time. Its components, particularly the rubber hose systems and rubber gaskets, are subjected to greater chemical and mechanical stresses than just about any other household appliance. Moisture, detergents and cleaning agents, particularly alkaline agents, as well as high water temperatures must not have an adverse effect on the material. Due to the long service life of the washing machine, all polymer parts, especially rubber parts, need to have a service life of at least 10 years, which means excellent resistance to aging.
Extrusion
Davis-Standard introduced new compact extruder for coating applications
Davis-Standard introduced a new compact extruder engineered for extrusion coating applications – the CHP. The machine’s sleek design offers a smaller footprint and lighter weight to allow for easier addition to an existing carriage or platform structure. This provides processors with a space-saving replacement or coextrusion addition for increasing outputs and line speed

Trelleborg’s iCast LSR speeds small batch product development
Trelleborg Sealing Solutions is supporting manufacturers with iCast™ LSR, a new fast and flexible digital manufacturing process for product development and small batch production of Liquid Silicone Rubber (LSR) parts.
Trelleborg’s unique iCastTM LSR process offers a cost-effective way for manufacturers to develop product variations or try out different design concepts before investing in serial production tools. In addition, the process enables the start of pre-series and series production with small batches, to close the gap between low and high-volume production.

Lanxess new prepolymer degrades in aqueous and hot applications for oil and gas
LANXESS is adding to its extensive range of polyurethane (PU) systems for the oil and gas industry with a new prepolymer: Adiprene® Degrade 80C AQ90A. It can be used to manufacture elastomer components that can be deployed in temporary challenging applications and break down by themselves in warm (from 50 to 93ºC) and wet environments after a defined period of time
Testing & Instruments
How to increase throughput when testing elastomers
When elastomers are being used in a manufacturing process, it is important to verify their physical properties by performing testing
at all stages of production. When researching and developing new elastomers, such as those used in tires, extensive testing is required to verify and validate each elastomeric compound. Research and development facilities for elastomeric materials will sometimes go through hundreds or thousands of specimens before moving on toward production. During production, testing is typically performed for quality control purposes
Molding
Troubleshooting a mold for injection molding
Opportunities abound in the rubber industry for polymers/ingredients suppliers, compounders,
processors, designers, mold makers and end users to embrace polymer flow analysis.
Thermoplastic Elastomers & Urethanes
Novel value-added thermoplastic elastomers bonding to polyamides
Bonding thermoplastic elastomers to polar and non-polar substrates has been widely studied in the past few decades to create products that enhance ergonomic comfort and functionality. Overmolding a TPE compared to two-shot molding is a litmus test for bonding the material to the substrate. The TPE must wet the cold surface and must melt a few nanometers of the surface of the substrate that is being overmolded on to facilitate bonding.
