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.
New versions of BASF's Ecovio line are both compostable and designed for either injection molding or thermoforming. These combinations are becoming more common for the single-use bioplastics used in food service and food packaging applications, but are still not widely available.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This radio show will show what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
