Product Texts
Material code according to ISO 1043-1: PP

Heat stabilized polypropylene reinforced with 40 weight percent long
glass fibers. The fibers are chemically coupled to the polypropylene
matrix. The pellets are cylindrical and normally as well as the
embedded fibers 10 mm long.

Parts molded of CELSTRAN have outstanding mechanical properties such
as high strength and stiffness combined with high heat deflection.
The notched impact strength is increased at elevated and low
temperatures due to the fiber skeleton built in the parts. The long
fiber reinforcement reduces creep significantly.

The very isotropic shrinkage in the molded parts minimizes the
warpage. Complex parts can be manufactured with high reproducibility
by injection molding.

PREPROCESSING

Drying is not necessary because of the negligable absorption of
humidity. If water is condensed on the pellets, it is recommended to
dry in a dehumidifying dryer at 80 °C for about 2 hours.




PROCESSING

During the processing of CELSTRAN it is important to watch and
control melt shear, for excessive shear reduces fiber length and
mechanical performance as well.

Processing recommendation:

- Conventional 3 zone screw, screw diameter minimum 40 mm
- Design flow channels for low melt shear
- Back pressure and screw rotation to realize a continous
plastification performance and thus a homogeneous melt.
- Apply higher temperature settings than for short fiber compounds

Melt temperature (in the srew anteroom) 260-290 °C
Mold surface temperature 40-70 °C
