CELSTRAN® PP-GF40-0414P7/10
 
CELSTRAN PP-GF40-0414 P7/10 | PP | Glass Reinforced
 
Description
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 7mm 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.
 
Application field: Functionial/structural parts for automotive
