New nylon nano-composite superior performance

A new nanoclay-filled nylon series, Dinalon, was newly developed by CrupoRepol, Spain.

The Dinalon series contains fine layered clays that are attached to PA resin and dispersed in PA by the action of organic compounds. According to Grupo Repol, lamellar clays are dispersed in the resin to form a sheet-like net, which improves the mechanical, thermal and barrier properties of the resin. The change in the resin density is small, and it has no effect or impact on the impact and processing properties of the resin. influences. . The rigidity of PA nanocomposites with nanoclay content of 8% is similar to that of 20%-30% inorganic fillers filled PA compound. Therefore, the company believes that Dinalon has the potential to become an inorganic-filled plastic for components that require high lightness.

The addition of nanoclays significantly increases the material's heat distortion temperature (HDT), which is an ideal alternative to high-cost, heat-resistant and high-rigidity plastics. PA nanoclay composites have significantly better barrier properties than unfilled PAs, opening the door for applications in food and medical packaging. Grupo Repol also developed a PA nanocomposite with high impact PA properties with a rubber-like structure. The addition of nanoclay increases the material stiffness and decreases the elongation at break, but still maintains the original flexibility and impact resistance of the PA. .
