These compounds are made for OEM applications such as strain relief, potting and encapsulating, forming nonscratching holding fixtures and edging and sealing felt belts and dryer fabric in the paper industry. The urethanes are castable, nonshrinking and waterproof, resisting abrasion, vibration, and temperature cycling indoors or out. They can take service temperatures up to 350F, but can cure at room temperature. They put out no VOC emissions, come in several viscosities with cured hardnesses from Shore A 78 (or lower with Flex-Add™ additive) to Shore A 97, tensile strengths to 3300 psi, tear resistances to 515 pli, and dielectric strengths to 350V/mil. The company's Flex-Add product can make Flexane 80 more flexible, and Flexane Accelerator can shorten curing times, even at temperatures as low as 30F.
The engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
The age of touch could soon come to an end. From smartphones and smartwatches, to home devices, to in-car infotainment systems, touch is no longer the primary user interface. Technology market leaders are driving a migration from touch to voice as a user interface.
Soft starter technology has become a way to mitigate startup stressors by moderating a motor’s voltage supply during the machine start-up phase, slowly ramping it up and effectively adjusting the machine’s load behavior to protect mechanical components.
A new report from the National Institute of Standards and Technology (NIST) makes a start on developing control schemes, process measurements, and modeling and simulation methods for powder bed fusion additive manufacturing.
If you’re developing a product with lots of sensors and no access to the power grid, then you’ll want to take note of a Design News Continuing Education Center class, “Designing Low Power Systems Using Battery and Energy Harvesting Energy Sources."
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
