Properties of Ultraform^® (POM)

Ultraform^® can be thermoplastically processed and has a partially crystalline structure with a high degree of crystallization. It is produced by the copolymerization of trioxan and another monomer. It consists of linear chains in which the co-monomers are firmly incorporated in a statistically distributed manner. These co-monomer units account for the high stability of Ultraform^® during processing and when exposed to long-term heat and to chemicals. It surpasses by far the resistance of homo-polymeric polyoxymethylene.

Processing of Ultraform^® (POM)

Ultraform^® can be processed by all methods suitable for thermoplastics. The most important methods are injection molding and extrusion. Injection molding allows even the most complicated moldings to be mass-produced very economically. The extrusion process is used to manufacture rods, pipes, profile sections and sheet, most of which are further machined by means of cutting tools to form finished parts.

The Ultraform^® Product Line

The Ultraform^® product line encompasses grades for processing by means of extrusion and injection molding. The following product groups exist:

Conductive Grades

Improved surface resistivity, conductivity in electricity for antistatic or electrical conductive devices and parts to avoid electrostatic discharge.

Drinking Water Grades

are recommended for applications where drinking water and food contact approval is a prerequisite.

For the extrusion of thin-walled as well as thick-walled tubes and panels, hollow profiles and semi-finished products having wall thicknesses of up to 50 mm and more. These are made into gear wheels, bearings and other machine elements by means of non-cutting procedures.

Extrusion Grades

Hot Diesel Grades

Grades with special treatment for purposes of improving light resistance, UV resistance and weathering resistance.

Grades for applications that make particularly high demands in terms of the toughness. There are TPU-modified grades as well as grades containing rubber, each with differing contents of impact modifiers. The products containing rubber exhibit a number of advantages for processing technology such as, for instance, high weld line strength.

Impact-modified Grades

Grades with special treatment for purposes of producing especially low-odor parts, e. g. for the interior of vehicles.

Low Emission Grades

Grades with special treatment for purposes of producing especially low-odor parts, e. g. for the interior of vehicles.

MedTech Grades

Grades that offer a wide service package including a long-term recipe consistency, tailor-made especially for requirements in the medical-technical market.

Reinforced Grades

With differing mineral contents for low-warpage and dimensionally stable molded parts that display increased stiffness, hardness and heat distortion resistance
With differing glass fiber contents for applications entailing very high demands in terms of strength, stiffness, hardness, creep resistance and dimensional stability under heat
