Application of Polypropylene (PP)

1) injection molding products: is the largest application area of ​​polypropylene, products include turnover boxes, containers, suitcases, auto parts (automotive interior parts, such as dashboards; fenders, ventilation ducts, fans; bumper), home Electrical parts, medical instruments (disposable syringes), instruments (dishwasher door liners, dryer air ducts, washing machine frames and covers, refrigerator door liners, consumer goods (lawn and garden equipment such as lawnmowers) And sprinklers, etc.) and furniture.

2) Extruded products: Made of polypropylene fiber, polypropylene film can also be made, in which the strength and transparency of the biaxially stretched film are greatly improved, and it is an important polymer material for packaging.

Polypropylene is the most widely used general-purpose plastic. It can be used as a plastic or can be spun into fibers (PP). Polypropylene is a low-absorbency, high-corrosion fiber that can be used in clothing and furniture, especially for woven carpets. It can also be extruded or blow-molded into thin films, then cut into flat strips for drafting, making woven bags, or as a strapping material - packing tape. Polypropylene composite films have developed rapidly in recent years and can be used for moisture, air separation and cooking, and are used as flexible food and beverage packaging.
Polypropylene pipes are used to transport hot water - PPR pipes, industrial waste water and chemicals.
Plates are used to make containers.

3) Thermoformed products: Sheets are thermoformed to produce thin-walled products that are used as disposable food containers – drinking cups.

Others, such as blow molded products, polypropylene is widely used in food packaging, such as yogurt containers, hot-filled beverage bottles. toy. It is also possible to produce block polypropylenes with isotactic and random segments, respectively, by special catalytic methods (metallocene catalysis). This polypropylene is similar in properties to rubber.
