Fiber-Reinforced & Low-Volatility LSRs Unveiled

By: Lilli Manolis Sherman 24. March 2015

Fiber-reinforced and low-volatility LSRs are being launched at NPE2015 by Momentive Performance Materials, Waterford, N.Y.

 

            • Applications requiring the features of silicone rubber and the strength of fiber reinforcement—such as wrist bands for wearable electronic devices, can obtain the combination of mechanical properties by using MPM’s new Silopren Matrix 70 fiber-reinforced LSR. Compared to standard LSR of the same hardness, this material has demonstrated 30% higher torsion resistance and 100% higher modulus—properties that may save manufacturers the cost of incorporating a fabric layer into their products. Silopren Matrix 70 also boasts excellent UV resistance and can be easily colored. The product may also be considered for use in some healthcare applications such as wearable electronics or diaphragms pursuant to FDA regulations and ISO 10993.

 

            • The company’s new non-post-cure, low-volatility self-lubricating LSR Silopren LSR 3376/50 boasts very low volatile levels without post-curing. It is engineered to help automotive manufacturers produce electrical connector seals that meet increasingly stringent safety specifications, This is the first product in MPM’s new low-volatility, self-lubricating LSR family. It has a 3% oil content and contains less than 350 ppm of total volatiles. The material typically has a nominal hardness of 50 Shore A, a low compression set of 16% and its can be easily colored. The material was developed to meet new stringent global automotive specifications.

Carbon Fiber Filament For New 3D Printing Capabilities

By: Lilli Manolis Sherman 23. March 2015

 

Just last year, Eastman Chemical and Helian Polymers of The Netherlands, a leader in filament 3D manufacturing, teamed up to launch a 3D printing filament under Helian’s ColorFabb brand based on Eastman’s Amphora 3D XT-copolyester. The material focuses on functionality and features strength, workability, processing, aesthetics and low odor for 3D printed products.

At NPE 2015, the partners are launching a further advance with new copolyester-based carbon fiber 3D filament-- ColorFabb XT-CF20, also based on Eastman’s Amphora 3D polymer—helping a Kickstarter campaign to revolutionize the industry and showcase new printing capabilities. The new material boasts high melt strength and viscosity, good dimensional accuracy and stability, low printing odor, and stiffness without being brittle. Its heat resistance, dimensional stability and stiffness combined are said to make it ideal for use in the fabrication of drones, aerospace and automotive parts, and prototyping.

Meanwhile, Stacker, is a fast and affordable commercial-grade 3D printer—the result of a manufacturer making a difference in 3D printing. The project to develop this new 3D printer was launched from a successful Kickstarter campaign and features ColorFabb XT-copolyester made with Eastman’s Amphora 3D polymer. The new low-odor, styrene-free polymer is uniquely suited for the 3D market and printers, meets regulatory compliance requirements, and it offers air quality and dimensional stability benefits. These benefits are said to be ideally suited for Stacker printers, which are now optimized to run ColorFabb XT-copolyester. 

Says Alex Dudal, market development representative at Eastman, “The 3D printing industry is progressing fast, and we’re constantly seeking new, exciting things happening—from the development of medical replicas and implants to 3-D printed cars. With Eastman’s Amphora 3D polymer, companies like Stacker are able to push the boundaries and created machines that can print more than one part at a time while still being affordable.”

DuPont Increases Capacity For High-Performance Nylon

By: Lilli Manolis Sherman 23. March 2015

 

DuPont Performance Polymers has announced it increased production of its Zytel HTN PPA manufactured at its Richmong, Va. Facility by 10% to meet growing global market demand in automotive and consumer electronics sectors.

           Zytel HTN PPA fills a valuable need because it bridges the performance gap between nylon and more expensive specialty polymers while maintaining ease of processing. This allows component designers to replace more metal for lighter weight components or to replace other materials to deliver lower overall system costs. Demand is growing in the automotive industry because the material can stand up to long-term exposure in aggressive temperature and chemical environments that stretch the performance of nylon 66. In the electronics and hand-held device market, Zytel HTN is a go-to resin because of its performance, dimensional stability and its ability to withstand lead-free soldering environments,” says Brian Fish, global business manager for high-performance nylons.

 

            The material is often used by the automotive industry to make engine cooling components, such as thermostat housings and water pumps, and to make powertrain components, such as charged air coolers, transmission housings, engine oil systems, brake systems, ignition systems and motors. In electrical and electronics markets, this nylon is often used to make lead-free SMT (surface-mount technology) and traditional connectors, high-voltage insulators and structural components for hand-held-devices.

ExxonMobil To Host Seminars On Packaging & Stretch Film at NPE

By: Lilli Manolis Sherman 16. March 2015

Yet another major materials supplier has plans to hold seminars on key topics at NPE2015, and have experts on hand for individual discussions throughout the show. Exxon Mobil Chemical plans to demonstrate how its broad portfolio of globally available performance polymers can help customers create new products for modern living. The company’s location will be at the NPE2015 Discovery Center located in the West Hall, Level 2 (W204).

 

With a focus on applications, the company will emphasize Exceed and Enable mPE resins, Escor EAA resins, Optima EMA resins, Escorene Ultra EVA resins, Vistamaxx performance polymers and its PP resins. The company will also introduce two new Exceed mPE resins and two new Vistamaxx polymers, and present new applications for its performance polymers: aseptic packaging; extrusion coating for flexible packaging; standup and pillow pouches; BOPP/cPP sealants; and, machine stretch innovations.
