Low-cost, vertically integrated cyanate ester system from Nexx Technologies has an extended out-time and is capable of parts production in and out of the autoclave.  

NEW YORK, January 20, 2023 – The Enduredge NTC-425 cyanate ester system is the latest high-performance product released by Nexx Technologies, manufacturer and supplier of prepreg materials and an affiliate of Mitsubishi Gas Chemical America (MGCA, New York, N.Y., U.S.). 

The low-cost novel prepreg resin system is said to be unique within the composites industry because it is vertically integrated, with a shop temperature out-time of 90-100 days (<75ºF). Extended out-time enables companies to construct and assemble large-scale structures before the prepreg reaches the end of its processing shelf life. The NTC-425 architecture is also capable of parts production via out of autoclave (OOA) without the need for complicated debulks or curing processes; its flexible processing also enables autoclave and vacuum bagging production methods. 

According to Nexx Technologies, Enduredge NTC-425 prepreg creates Z-directional engineered air release channels that offer optimized vacuum bag-only (VBO)/OOA capabilities. Additionally, NTC-425 initially cures at a lower temperature (121ºC), ensuring dimensional stability for parts that will then be post-cured off the tool (freestanding). As a result, the fabricator can then use lower temperature capable tooling. After post-cure, the material reaches a final Tg of 200°C.

“NTC-425 provides excellent mechanical properties along with low moisture absorption and outgassing,” Joseph Kidd, general manager at Nexx Technologies, says. “For projects that may require an extended time to layup, NTC-425 is the ideal choice for its unbeatable out-time. Our vertical integration of cyanate ester resin production will allow us to provide a definite advantage to our customers in both availability and costing.”

Enduredge NTC-425 Cyanate Ester System is available in numerous carbon fiber fabrics, fiberglass and quartz, as well as unidirectional tapes (UD). Ideal applications range from larger structures, high service temperatures and radomes.

NEXX Technologies, manufacturer and supplier of innovative prepreg composite materials, has earned AS9100 certification by meeting the requirements with its comprehensive quality management system (QMS), a standard of quality required within the industries of aviation, space, and defense.

NEW YORK, October 17, 2022 (Newswire.com) – NEXX Technologies passed a stringent audit set by the American Systems Registrar (ASR) that evaluated the company’s research, development, manufacture, and testing of its prepreg materials. The assessment benefits aerospace manufacturers and suppliers with validation of product quality and assurance, with the standard ensuring exposure for growth and expansion across the advanced engineering market.

With AS9100 certification, NEXX Technologies customers can rest assured their product orders will be met to the highest of safety standards, with unbeatable quality performance for modified epoxy and Cyanate Ester thermoset prepreg materials.

“Certified AS9100 exemplifies NEXX Technologies’ commitment to its products and to its customers,” said Joseph Kidd, General Manager at NEXX Technologies. “We continue to demonstrate world class service in next generation prepreg technology. With this latest certification, NEXX Technologies will build on the foundations of unprecedented quality within products and support.” 

Enduredge Max Modified Epoxy Prepreg Fabrics and Tapes will be offered through Airtech International

NEW YORK, March 25, 2022 (Newswire.com) – Mitsubishi Gas Chemical (MGC) announced Airtech International Inc. as its global distribution partner for its NEXX Technologies business division. Airtech will be distributing NEXX Technologies’ Enduredge Max lines of modified epoxy prepreg fabrics and unidirectional tapes in the USA, China, Europe and the UK.

“When devising our materials growth strategy, Airtech was at the forefront for global distribution,” said Joe Kidd, General Manager – NEXX Technologies. “Airtech’s position in the composites market with their composites’ fabrication focus makes them the ultimate distribution partner for NEXX Technologies’ Enduredge Max prepreg fabrics.”

Airtech boasts six manufacturing/distribution centers worldwide, making quick and reliable delivery of materials possible. Domestic distribution centers are in California and Tennessee. International locations include Luxembourg, England and China, with additional expansion underway.

The Enduredge Max portfolio of modified epoxy prepregs offers performance and processing characteristics suitable for aerospace, space, Radomes and defense. These advanced materials deliver extended out time and excellent vacuum bag-only processing. They do not require freezer storage and can be stored at room temperature for up to a year without any changes in rheology or processing conditions. “Due to the unique stability of the Enduredge Max products, Airtech will be able to fulfill and deliver at dramatically shorter lead times than legacy prepreg products,” concluded Mr. Kidd.

Enduredge Modified Epoxy Product lines include NT-300, which provides excellent strength and toughness while providing an outstanding surface finish, making it ideal for any parts requiring high cosmetically appealing appearance; NT-350, designed for aerospace secondary and primary structures, space and satellite structures and Radomes; and NT-350HT, which offers high strength and high impact resistance, perfect for Radomes applications.

“As a technical partner to our customers, we recognize NEXX prepregs deliver unique enabling features for multiple applications and processes. Their products display excellent mechanical property laminates with high-quality surface finish, no freezer storage, enabling flexible workflows, reduced waste and lower energy usage, and thicker laminate capability,” expressed AirTech President/CEO Jeff Dahlgren. “As a global supplier to the composite industry, we are convinced this industry-advancing partnership will drive innovation and development, bringing game-changing advantages to our customers.”

NEXX Technologies will be showcasing the Enduredge Max products in the Airtech booth, as well as their own, in the upcoming Paris, France, JEC Show in early May. NEXX Technologies is located in southern California with administrative headquarters within Mitsubishi Gas Chemical America located in New York City.
