This specification describes material types of unfilled
Polyoxymethylene (POM), also known as acetal, that are used in
injection components for interior trim that are not Ultraviolet
(UV) stable.
Types. The classification into groups is
according to the different properties as described in Table 1.
Symbols. All plastic parts must have legible
plastic compound identification symbol per GMW3116 and ISO 11469
requirements – POM.
Applicability. Typical applications include
non-visible parts such as fasteners, pins, gears, and other small
parts not requiring dimensional stability.
Remarks. Types: The following types apply to
this specification.
• H1 – Low Melt Flow
• H2 – Medium Low Melt Flow
• H3 – Medium High Melt Flow
• H4 – High Melt Flow
