Polyamide 6 for Weight Reduction and Metal Replacement

Weight reduction is a crucial factor in product design in certain markets such as aviation and automotive, with the goal of reducing fuel consumption, CO2 emissions, and improving dynamic performance.

To achieve this reduction, the PROMYDE PA6 range offers two main approaches:

  • Development of lighter polymers: The aim is to develop engineering polymers with properties similar to those of currently used materials but with lower density.
  • Substitution of higher density materials with technical engineering polymers: This involves replacing heavier materials, such as metals, with technical polymers that meet the required properties.

Lightweight polyamides 6 for weight reduction

PA6 Nano Clay (NC)

Propiedades de los grados de Promyde reforzados con nanoarcillas para soluciones de reducción de peso.

Reinforced grades with PROMYDE Nano Clay contain clay nanoparticles embedded in the polymer matrix, improving properties and reducing weight.

PA6 Weight Reduction (WR)

Propiedades de los grados de Promyde para reducción de peso con o sin refuerzo.

Our WR grades offer a lighter alternative for weight reduction while maintaining the same properties as conventional materials.

PA6 reinforced with Hollow Beads (HB)

Propiedades de los grados de Promyde para reducción de peso con esferas huecas de vidrio.

PROMYDE HB grades use hollow glass beads as reinforcement, providing an additional weight reduction of up to 20%.

PA6 for Replacing Heavy Materials in Differents Areas

  • Substitution of metals with electrically, thermally and electrically & thermally conductive polymers.
  • Substitution of metals with solutions with high modulus and resistance to high temperatures.
  • Substitution of solid parts with hollow alternatives manufactured through water or gas-assisted injection.

In summary, PROMYDE offers a wide range of options for weight reduction in injection-molded parts, providing benefits in terms of energy efficiency and performance.
