The characteristics of the main raw materials selected by the hollow blow molding factory The production raw materials needed by hollow blow molding plants include polypropylene, polyethylene, linear polyester, etc., among which high-density polyethylene accounts for a large proportion. The high-density polyethylene used in hollow blow molding is also called low-pressure ethylene, and its English name is HDPE. The advantages are acid and alkali resistance, low temperature resistance, flexibility, surface hardness and tensile strength and other mechanical strengths. It has advantages over LDPE and has strong crack resistance. It has good corrosion resistance, so it is used in most occasions. Most of the raw materials used in hollow blow molding factories are HDPE, because of reliable quality and affordable price. h DPE is a very strong plastic commonly used in industrial containers. Of course, HDPE is also an environmentally friendly material and can be recycled repeatedly. Of course, if the hollow blow molding factory chooses HDPE for production, it also needs to pay attention to its weak points, that is, it will be deformed, aged, brittle, and its air permeability is relatively poor. When using hollow blow molding to produce raw materials, try not to use other grades of raw materials, which will reduce the service life of blow molding products.
