Ultraform® H2320 004 AT
High-Performance Acetal (POM) Copolymer for Precision Extrusion
A high-molecular-weight, unreinforced extrusion grade offering exceptional melt strength, long-term thermal stability, and superior chemical resistance for demanding engineering applications.
Material Profile & Architecture
Identification & Classification
Ultraform® H2320 004 AT is a high-performance acetal copolymer (POM-K) designed for general-purpose extrusion.
ISO 1043-1:
POM
Full ISO Designation:
ISO 29988-POM-K,,E-GNR,1-2
The Copolymer Advantage
The copolymer architecture introduces C-C bonds that act as "stoppers," halting thermal degradation. This provides two critical advantages over homopolymers:
- Enhanced Thermal Stability: Wider processing window and reduced risk of outgassing.
- Superior Chemical Resistance: Robust against alkaline solutions and hot water.
High-Melt-Strength Extrusion Grade
Its high molecular weight results in high melt strength, crucial for maintaining shape integrity in extruded profiles like tubes and panels.
Melt Volume-Flow Rate (MVR)
3.08 cm³/10min
(ISO 1133, 190°C/2.16kg)
Application Engineering
Primary Applications: Thin-Walled Extruded Profiles
The high melt strength of H2320 004 AT makes it the ideal choice for producing small, thin-walled tubes, panels, and profiles with tight tolerances and exceptional dimensional stability.

Critical Safety Information
Primary Hazard: Thermal decomposition above 240°C produces hazardous formaldehyde gas.
Mitigation: Strict process temperature control is a fundamental safety requirement. Ensure adequate local exhaust ventilation over machine nozzles.
Incompatible Materials: Avoid ALL contact with halogenated polymers (e.g., PVC), as this can cause violent, uncontrolled decomposition.
First Aid (Molten Polymer): DO NOT remove solidified plastic. Cool burn with large amounts of cold water and seek immediate professional medical treatment.
