To provide a molding material which holds the levels of mechanical characteristics, especially impact resistance and resilience, and is simultaneously substantially low in the release of formaldehyde.
The polyoxymethylene molding material comprises (A): 0.01-1.0 wt.% of a cyclic stabilizer containing at least one nitrogen atom in the ring; (B) 0.001-0.5 wt.% of a carboxylate; (C): 5-50 wt.% of an impact resistance-improving agent; (D): 0.0-2.0 wt.% of a steric hindrance phenol compound; (E): 0.0-1.0 wt.% of at least one stabilizer originated from the group of benzotriazole derivatives, benzophenone derivatives, and aromatic benzoate derivatives; (F): 0.0-0.8 wt.% of a steric hindrance amine (HALS) acting as a photostabilizer, and (G): the remaining amount of polyoxymethylene polymer.
