MATERIALS: New Extrusion Grade Nylon 410

Targeted to film, fiber, and monofilament markets is a new nylon 410 said to surpass other "green" nylons due to its much higher melting point.

A new higher-viscosity extrusion grade has been added to the biobased Exopaxx nylon 410 line from DSM Engineering Resins (U.S. office in Birmingham, Mich.). Targeted to the film, fiber, and monofilament markets, this resin is designed to provide excellent thermal stability, a broad processing range, and very good melt strength. Made of 70% from castor oil and reportedly 100% carbon-neutral, it is said to surpass other “green” nylons due to its far higher melting point (482 F/250 C), which suits it to lighting and under-hood applications.

Ecopaxx has the highest HDT values (@ 264 psi) of all biobased aliphatic engineering plastics, combined with excellent surface quality. Long-term, it has been shown to have excellent heat-aging, on par with nylon 6 at medium temperatures of 302-356 F (150-180 C). Far lower moisture absorption than nylons 6, 66, and 46 is claimed, which equates to superior retention of stiffness and strength after conditioning. In impact resistance tests, Ecopaxx performs at least as well as nylons 6 and 66. Its low rate of water vapor transmission and fuel permeability combines with very high puncture resistance to create good barrier films with transparency on par with nylon 6 but with less haze.
