Common materials for blow molding products

Do you know that the materials of plastic products are different? The plastic products we see in our daily life are actually made of more than a dozen different materials. The different materials determine the cost, scope of use and purpose of the product.

Blow molding, also known as hollow blow molding, is a rapidly developing plastic processing method. It is widely known that blow molding products as small as bottles, barrels, cans, boxes and all containers for packaging food, beverages, cosmetics, medicines and daily necessities. As large as the automotive industry, fuel tanks, car shock absorbers, seat backs, center brackets, as well as armrest and headrest coverings. Most of the products seen in life are blow molding products.

The rationality of blow-molded materials is related to the surface finish of plastic products. The common materials of blow-molded products that can be used in actual production are PP, PE, and PVC, each with its own advantages and disadvantages.

PP, short for polypropylene, is a colorless, odorless, non-toxic, translucent solid substance with good chemical resistance, heat resistance, and electrical insulation in machinery, automobiles, construction, textiles, packaging, agriculture, forestry, fisheries and food industries. It has been widely developed and applied in many fields.

PE, polyethylene is a high molecular organic compound formed by the addition polymerization of ethylene. It is commonly used as a food contact material. It is non-toxic, tasteless and odorless. It meets the hygiene standards for food packaging. Good gas-proof and insulating properties, and not easy to be damaged. The products are beautiful, strong, impact-resistant and corrosion-resistant. They can hold liquids and solids in chemical raw materials, pesticides, lubricants, coatings, medicine, food, hardware electronics, electromechanical and other industries. thing.

PVC and polyvinyl chloride are widely used in building materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, foam materials, sealing materials, fibers, etc.
