Solvay’s extensive portfolio of advanced polymers meets growing demand from instrumentation to implants
Solvay Specialty Polymers – a global supplier of high-performance thermoplastics offered for use in a range of markets including implantable and non-implantable medical devices – will showcase its broad portfolio of advanced materials for the healthcare sector at the North American Spine Society’s (NASS) annual meeting. For permanent and prolonged exposure implants and limited exposure devices, Solvay’s plastics deliver strong, lightweight performance along with design flexibility, ease of fabrication, regulatory compliance, and the ability to differentiate products and brands using colors.

ENERGYSAFE Graphite Black for solar reflective plastics
ENERGYSAFE pigments are designed to substantially increase the solar reflectance properties of plastics across a very wide color space. Plastics comprising ENERGYSAFE Graphite Black reflect up to 33 % of the incident solar energy, i.e. they exhibit a Total Solar Reflectance (TSR) of 0.33. Total Solar Reflectance optimized formulations restrict or even eliminate the use of carbon black. For comparison, plastics pigmented with carbon black have a TSR below 5 %. ENERGYSAFE Graphite Black can be used to adjust the darkness or L values of plastics article. ENERGYSAFE Graphite Black will contribute to decreasing the rate of absorption of sunlight. This effect can lower the overall heat build-up, thus leading to plastics with reduced surface temperature. Read More
High accuracy, open frame, thermally stable galvo scanner
The highly repeatable and thermally stable feedback sensors used on the AGV-HPO scanner systems can be calibrated down to single-digit, micron-level accuracy over the field of view. With the extremely low thermal gain drift performance of the position transducers, complex, high-density laser machining applications will maintain consistent micron-level feature placement accuracy over the lifetime of the process. Likewise, high throughput applications will maintain consistent part-to-part quality without having to re-calibrate between parts. Read More
Dymax micro-spray valve features contaminate-free dispensing
Dymax Corporation has released a more precise, flexible, and easier-to-use Model 455 Micro-Spray Valve. It features an inert, 100% disposable fluid path which carries materials from the material reservoir to the spray nozzle in a sealed path. This prevents materials from coming in contact with the valve’s inner components and ensures a contaminate-free dispensing process. The pneumatic pinch valve, outfitted with a stainless steel spray nozzle and spray regulator assembly, utilizes tube over-pinch, a feature that extends tube life, enhances repeatability, and offers precise control over material flow.

First melting with a flighted barrel!
As commercial interest in micro injection molding picks up for high-precision, speck-sized medical and electronic parts, so is R&D. Probably the most unusual development in decades is a novel one-piece melting and injection unit for micro molding, which melts with flights in a stationary barrel, not the rotating shaft. The idea behind the new technology is to reduce melt volume in the barrel, residence time, and risk of thermal degradation. Read More
