Comparison basis: GF content ISO 1172; tensile stress ISO 527; flexural properties ISO 178; notched Charpy impact at 23 °C ISO 179/1eA; HDT at 1.8 MPa ISO 75; water absorption at 23 °C and 50% RH ISO 62. These are typical web reference values. The catalog does not specify the dry or conditioned state of the mechanical data; confirm it in the grade-specific TDS before final selection.
Material properties
Material properties and molding
The properties of glass-fiber-reinforced PPA depend on the formulation and molding conditions.
Structural performance at elevated temperatures
Glass-fiber-reinforced PPA is considered for structural parts exposed to heat. Grade data includes tensile and flexural properties, heat-deflection temperature and water absorption.
- Higher stiffness and load response
- Higher tensile and flexural strength
- High heat-deflection screening values
- Dimensional control under load
- For structural parts exposed to heat
Heat exposure and part geometry
Temperature, load duration and environmental media define the operating conditions. Fiber orientation, weld lines and assembly restraint also affect strength and dimensions in the molded part.
- Thermal exposure, duration and load
- Moisture state and environmental media
- Fiber orientation and anisotropy
- Directional shrinkage and warpage
- Weld lines, gates and local stress
- Assembly constraints and functional evidence
Applications
Parts and applications
PPA grade selection relates mechanical and thermal data to the part's temperature, load, environment and dimensional requirements.
Processing
Molding and part testing
PPA comparisons depend on the test basis, material state and processing history. Molded-part trials assess thermal response, dimensions and assembled function under the intended conditions.
- 01
Temperature and duty cycle
Temperature, duration, load, cycling and environmental media define service conditions. HDT alone does not establish continuous-use temperature.
- 02
Test basis and material state
The grade-specific TDS supplies the basis for comparing critical properties. Published typical values support selection; production approval needs the project's full evidence.
- 03
Drying and processing
Grade-specific drying and processing guidance defines the trial conditions. Moisture and residence time are part of the molding record.
- 04
Fiber direction and local stress
Gate position, flow direction, weld lines, ribs and inserts influence the structural response along the part's load path.
- 05
Dimensions and warpage
Published shrinkage ranges support initial selection. Measurements with the intended mold and conditioning sequence establish dimensions and warpage for the actual geometry.
- 06
Assembled function
Part and assembly tests address thermal, mechanical, environmental and repeatability requirements. Supporting documents complete the production-approval record.
