Engineered for extremes
PTFE Glass 15
Sample data. This grade shows how a Pascalor datasheet looks. The values are not measurements of a real product.
15 wt% glass fibre. A softer glass grade that keeps more sealing ability than the 25 % grade while cutting wear and creep against virgin PTFE.

Typical values are mean results on compression-moulded and sintered test plaques made in the laboratory unless a method says otherwise. Properties of a finished part depend on the moulding or ram-extrusion route, the sintering cycle and the direction of flow. Limits apply to lot release. They are not a warranty of fitness for a particular use. Confirm suitability on your own counterface, fluid and temperature.
