CELSTRAN PP-GF40-0414P10/10 PP 
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.

Application field: Functionial/structural parts for automotive

Celstran LFRT（長(zhǎng)纖維增強(qiáng)熱塑性塑料）是用拉擠工藝技術(shù)制備而成。在制備過程中，拉擠工藝使長(zhǎng)纖維均勻地滲透在塑料基體內(nèi)，從而達(dá)到了優(yōu)化的增強(qiáng)效果。與常規(guī)的短纖增強(qiáng)材料不同，Celstran LFRT部件中具有更長(zhǎng)的纖維，而且它們相互纏繞，形成了一種纖維骨架，它能限制各向異性收縮，顯著降低翹曲.LFRT技術(shù)并不僅限于玻纖，它可以通過使用玻纖、不銹鋼纖維、碳纖、芳香纖維和其它增強(qiáng)纖維，來提供滿足各種苛刻應(yīng)用的綜合性能.
