Drying Guidelines

Like many other plastics, TECASINT also demonstrates hygroscopic behaviour, i.e. the plastic can absorb water, generally in the form of humidity. This absorption of water is reversible, i.e. the absorbed water can be completely removed again by drying.
Dimensional deviations ocurring until the complete saturation of finished parts may be as high as 0.4% in the worst case, depending on the material used. However, this condition does not occur quickly but over a period of several weeks (guide value dia. 20 mm, around 0.02 mm).
When manufacturing high-precision components, we consequently recommend drying the parts before processing in order to remove any remaining water.  Components with an application temperature of over 250°C should also be dried in order to prevent bubble formation in the material due to excessive vapour pressure.
