Conclusions
The introduction of fiberglass somewhat increases the swelling of polypropylene in acidic media, but due to the preservation of a high level of mechanical properties, it permits one to increase the operational lifetime of parts and to reduce warping.
From the test results, glass-filled polypropylene of the Komponor grade is recommended for introduction for operation in the aggressive media of man-made fibre manufacturing.
