As a lead-acid batteries used in polypropylene tank should have high strength and modulus shrinkage, excellent impact resistance and good heat resistance and shape, but the unique characteristic of polypropylene impact resistance is poor, especially in low-temperature impact worse performance, especially in cold weather in the northeastern region, with pure polypropylene battery compartment often occur at low temperatures using the phenomenon of bursting. To this end, we chose low temperature performance of ethylene propylene copolymer as a base resin, adding the appropriate scores of other materials and additives, made by blending a twin-screw extruder, to obtain the strength, low-temperature impact strength, flow adjustable battery slot Polypropylene Compound.
The factory production of the battery slot Polypropylene, close to its performance, meet or exceed the U.S. PRO-AAX7523 battery slot Compound level.
