CELSTRAN® PA66-GF50-02 P11/14

 

CELSTRAN PA66-GF50-02 P11/14 | PA66 | Glass Reinforced

 

Description
Material code according to ISO 1043-1: PA66

 

Heat stabilized Nylon 66 reinforced by 50 weight percent long glass fibers. The pellets are cylindrical and normally as well as the embedded fibers 11 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.

 

Can be used for substituting die cast metal with the advantage of Weight reduction, no corrosion problems, no post treatment.

 

Other Processing
Injection Molding
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):310-325℃
Mold surface temperature:90-120℃
