The material of Plastic tubing is Polytetrafluoroethylene (PTFE). PTFE is a thermoplastic polymer, whose properties are gained from the aggregate effect of carbon-fluorine bonds.
PTFE's coefficient of friction is as low as 0.05 to 0.10, which is known as the third lowest of solid materials. The temperature range is from –234°C (–454°F) to 260°C (500°F). Its high melting temperature makes it suitable for use in high temperature applications. Combined with its chemical inertness and chemical resistance, PTFE outperforms glass and graphite, making it an excellent material for chemical and analytical researches and fluid transfers. It can be steam sterilized with its physical properties unaffected, such as its surface hardness, flex life and deformation under load. All these features make this special high temperature plastic tubing an excellent choice as protection from chemical contact or temperature extremes.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
