MATERIALS:Solvay Advanced Polymers‘ broad portfolio of KetaSpire® polyetheretherketone (PEEK) and AvaSpire® modified PEEK resins now includes five wear-resistant grades. These formulations provide an effective all-plastic alternative to more complex metal-based designs with rolling components for high-temperature friction and wear applications in lubricated and non-lubricated environments. The offering includes two KetaSpire PEEK products and three AvaSpire modified PEEK materials designed for high-performance injection molded applications, including seal rings, thrust washers, brake components, gears, and needle bearing replacements for the automotive, industrial, and heavy-duty equipment industries.KetaSpire PEEK is one of the industry’s most chemically resistant plastics, offering excellent strength, superior fatigue resistance, and a heat deflection temperature up to 315C (599F). In this product family, KT-820 SL30 is a graphite/carbon fiber/PTFE-filled grade for non-lubricated and lubricated applications. In non-lubricated environments, it features a limiting PV value (contact pressure times velocity) of 75,000 psi x fpm and exceptional ease of processing, according to Brian Stern, senior global automotive market manager for Solvay Advanced Polymers. The line also includes KT-820 SL45, a carbon fiber/PTFE grade for lubricated environments.
The AvaSpire line of proprietary PEEK-based compounds includes AV-755 SL45, a carbon fiber/graphite-filled grade for high load-bearing applications in lubricated environments. Two carbon fiber/graphite/PTFE-filled grades include AV-742 SL30 (high melt flow) and AV-722 SL30 (low melt flow) for both non-lubricated and lubricated environments. An important advantage of all AvaSpire grades is their comparable strength and modulus, and equivalent or better chemical resistance versus comparable PEEK grades at up to a 30 percent cost reduction.
By experimenting with the photovoltaic reaction in solar cells, researchers at MIT have made a breakthrough in energy efficiency that significantly pushes the boundaries of current commercial cells on the market.
We looked at a number of sources to determine this year's greenest cars, from KBB to automotive trade magazines to environmental organizations. These 14 cars emerged as being great at either stretching fuel or reducing carbon footprint.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
