Made from Nylon PA66 which has high heat tolerance and can be used within an environment up to 120 C while still maintain strength and other physical performance (melting point around 180-200 C). The material has excellence resistance toward chemical, corrosion, abrasion, oil, impact (even at sub-zero temperature), and tension)
Still, white Nylon PA66 will yellow after a period of exposure to UV light, heat, and chemicals. The material will affect somewhat by UV light so it is suggested to avoid usage under direct sunlight. PA66 does have lower flowability compared to PA6, hence the surface of the model will not be as polished as the screw made from PA6. And will also absorb some water which causes the changes in the tightness of each component over time (usually became tighter) but will not be visible to normal visual inspection.
