PP can improve the rigidity, heat distortion temperature, lower mold shrinkage and linear expansion coefficient. T Series grades with high rigidity, high heat resistance, etc., for the interior, heater cover, filter housing and other auto parts, machinery parts and appliances shell; C series grade with good toughness, good whiteness, etc. can be used for car interiors, handles and a variety of commodities, machinery housings, plate and frame filter press shell, etc.; B Series grades with good gloss, good whiteness, high heat resistance, etc., can be used for rice cooker parts, small appliances such as Shell.
