Scope

This part of GB/T 36374 specifies sulfone polymers including polysulfone (PSU), polyethersulfone (PESU) and polyphenylene sulfone (PPSU).
A naming system for molded and extruded materials that can be used as a basis for classification.
The type of sulfone polymer material is graded according to the following characteristic properties, and based on composition blending, recommended use, and/or processing
Information on methods, important properties and additives, colorants, fillers and reinforcing materials are classified according to the classification method.
a) load deformation temperature;
b) melt mass flow rate;
c) notched impact strength of simply supported beams;
d) tensile modulus of elasticity;
e) Tensile yield stress.
This section applies to all sulfone polymers containing etheroxy groups, which are essential components of such polymers and are also suitable for inclusion in associations.
A sulfone polymer of benzene structure.
This section applies to powders, granules or granules of general-purpose materials that have not been modified or modified with colorants, additives, fillers, etc.
This section does not mean that the same material must have the same performance. This section does not provide for the specific use of materials and /
Or data on engineering data, performance data, or processing conditions required for processing methods.
These additional properties can be determined as required by the test method specified in GB/T 36374.2.
Additional requirements may be specified in Character Group 5 (see 3.1) in order to specify the specific use of a thermoplastic material or to ensure process reproducibility.
