Abstract
The present disclosure is generally directed to a fiber reinforced polyoxymethylene polymer composition having extremely low formaldehyde emission characteristics. The polymer composition generally contains reinforcing fibers in an amount from 3% to 70% by weight. The reinforcing fibers are combined with a polyoxymethylene polymer having a relatively high melt volume flow rate. The polymer composition can also contain a coupling agent for better integrating the reinforcing fibers into the polymer matrix. In addition to low emission properties, the polymer composition of the present disclosure displays excellent mechanical properties.
