Zeniva PEEK (polyetheretherketone). One of the most chemically resistant plastics available, PEEK also exhibits high strength and stiffness along with excellent toughness and fatigue resistance.
Proniva SRP (self-reinforced polyphenylene). Described as the stiffest and strongest unreinforced thermoplastic available, SRP also offers exceptional chemical resistance and hardness.
Veriva PPSU (polyphenylsulfone). This polymer offers toughness combined with transparency and excellent chemical resistance.
Eviva PSU (polysulfone). PSU provides “practical” toughness in a strong, transparent polymer.
New production processes and significant testing was required to make these materials eligible for implants. These efforts included meeting the relevant aspects of the current Good Manufacturing Practice (GMP) guidelines of the Food & Drug Administration’s 21CFR Part 820 Quality Systems Requirements and ensuring manufacturing operations are in compliance with relevant aspects of the ISO 13485 Quality Management System for the manufacture of medical devices.
OEMs evaluating the new materials include Zimmer Medical, a leading orthopedic supplier based in Warsaw, IN. The market for knee implants alone is $5.2 billion annually and is growing at an 8 percent clip, estimates Zimmer Chief Financial Officer James T. Crines.
What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
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.
