Transparency and impact resistance together.
{{SALTI}}Materials › Polycarbonate (PC)
When the part must take a knock without breaking, or let light through. Here reinforcement matters less than elsewhere: it is filled lightly, and filled to stiffen without losing toughness altogether.
Stress cracking is its weak point: in contact with certain solvents, oils and adhesives it cracks under residual stress, even months later. It must be dried carefully and is attacked by alkalis.
Tough, and transparent when needed
Covers, guards, housings that must take impacts.
Stiffer, still workable
Parts that must stay flat and hold tolerance under load.
Each row is the median of a selection of manufacturers’ datasheets held in our archive, with the property, the standard and the number of grades stated next to the value. These figures describe the sample: they serve to compare the levels with one another, not to size a part, and they are not a guaranteed material specification. For that you need the datasheet of the chosen grade, which we supply on request.
Where a level shows no value, the documented sample was not sufficient: we prefer to remove the figure rather than publish one that does not hold. HDT and impact strength are deliberately absent, because datasheets often do not state the test condition — whether HDT is at 1.8 or 0.45 MPa, whether the impact specimen is notched — and values collected under different conditions cannot be compared.
Parts that came out of our own machines: geometries that elsewhere would need moulds, finishes obtained in house.
