A new resin for glass fiber reinforced amorphous polymer solutions: Novadyn™ DT/DI polyamide

Face any of the following challenges? Start a discussion with INVISTA


Novadyn™ DT/DI has very good chemical and stress crack

resistance in many hydrocarbon environments where

Does your application require a combination of

high strength, high stiffness, and good dimensional stability?

Would a high Tg material help maintain properties in temperatures up to 120oC?

Could you benefit from a lower-cost alternative to current transparent nylons?

Does your part need scratch resistance without coating?

Would you like to replace a glass fiber (GF) reinforced polycarbonate with a GF material with very good chemical resistance?

Would you like to replace a GF reinforced high- cost amorphous nylon 12 with a lower-costs

amorphous polyamide?

polycarbonate fails.

With a Tg of 145 oC, Novadyn™ DT/DI maintains stiffness up to 120oC better than traditional nylons.

Novadyn™ DT/DI has better scratch resistance then


Transparent nylons have excellent processability, mold

shrinkage, dimensional stability, molding characteristics, and


Cost effectiveness

INVISTA is committed to becoming the transparent nylon cost

leader, building upon its integrated low-cost raw material


Recycled content

Novadyn™ DT/DI's unique combination of properties is derived

from DYTEK® A Amine, a monomer which is used in many high

performance polyamides. DYTEK® A Amine is typically 99%

pure and manufactured from recovered and refined materials

that would otherwise be burned with heat recovery, giving

Novadyn™ DT/DI at least 43% recycled content.1

Recycled content is defined by ISO 14021, section 7.8.
