Abstract: The present disclosure is directed to a process for producing a polyoxymethylene polymer or paraformaldehyde in an environmentally friendly and sustainable manner. The polyoxymethylene polymer or paraformaldehyde can be produced so as to be carbon neutral or even carbon negative. In one aspect, the polyoxymethylene polymer or paraformaldehyde is formed from a biogas or from a recycled gas. The biogas and the recycled gas are used to produce the components needed to form the polymer.

Abstract: The present disclosure is directed to a polyacetal, or polyoxymethylene (POM), base composition which contains an additive package containing additives suitable for food processing applications. Of particular advantage, POM produced according to the present disclosure may demonstrate low formaldehyde emissions, extractables, or both, when measured by standard methods without containing any formaldehyde scavenger packages.

Abstract: A medical grade polyoxymethylene polymer composition is disclosed that has been mass colored. The composition is particularly formulated so as to meet the standards of various governmental and safety requirements needed for use in medical applications and/or in food contact applications. In one embodiment, the polymer composition is formulated to meet the standards of USP Class VI testing and/or ISO 10993 testing.

Abstract: A process for the production of electrically conductive layers on the surface of plastics in which the surface of a plastic filled with electrically conductive constituents is irradiated with laser energy in such a way that the plastic is evaporated down to a predetermined depth at the point of incidence by the laser energy, leaving behind the electrically conductive constituents, which increase in concentration and thus form an electrically conductive layer. With the aid of the process, plastic moldings with integrated electrically conductive layers or tracks on the surface can be produced, for example components used in the electrical and electronics industries or other large or small plastic parts of any desired shape which are provided with conductive elements in certain places. The molding can also be a constituent of a composite article with other materials.
