Invista has launched Novadyn polyamides that are transparent polymers and used as differentiated blend additives to improve traditional nylon performance.

Novadyn polyamides are highly versatile semi-aromatic polyamides with a unique combination of performance, cost effectiveness, and recycled content. Novadyn DT/DI polyamide brings value to customers, who require parts that are both transparent and chemically-resistant, Invista said in a statement.

Novadyn DT/DI and Novadyn DT polyamides can also be used to modify crystallinity, boost glass transition temperature and reduce costs. These products can be considered for moulding, film, filament and fibre processing applications. Novadyn polyamides can be used in a variety of applications including automotive, electrical, industrial, and consumer products.

As a blend additive for traditional nylons, Novadyn DT/DI polyamide significantly improves conditioned mechanical properties for nylon 6,6 and nylon 6, including up to 43 per cent improvement in conditioned flexural strength and stiffness.

Allen Reihman, director of new business development for Invista said, “We designed Novadyn DT/DI polyamide for transparent applications where polycarbonate struggles with chemical resistance or where more costly transparent polymers may be over-specified.”

With leading brands including Lycra, Coolmax, Cordura, Stainmaster, and Antron, Invista is one of the world’s largest integrated producers of chemical intermediates, polymers and fibres. The company’s advantaged technologies for nylon, spandex, and polyester are used to produce clothing, carpet, car parts and countless other everyday products. (GK)
