Polypropylene is used in a wide range of applications. Do you know what?Let's take a look at this aspect of science.
1) Injection molded products: It is the largest application area of polypropylene. The products include turnover boxes, containers, suitcases, auto parts (automobile interior parts such as instrument panels; fenders, ventilation pipes, fans; bumpers), households. Electrical components, medical devices (disposable syringes), instruments (dishwasher door liners, dryer vents, washing machine frames and covers, refrigerator door liners, etc., consumer goods (turf and garden equipment such as lawn mowers) And sprinklers, etc.) and furniture. 2) Extrusion products: made of polypropylene fiber, can also be made into polypropylene film, wherein 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 versatile general-purpose plastic that can be used as a plastic or as a fiber (polypropylene). Polypropylene is a low-absorbency, highly corrosion-resistant fiber that can be used in clothing and furniture, especially for woven carpets. It can also be extruded or blown into a film, and then drawn into a flat yarn, a woven bag, or a tying material - a strap. In recent years, polypropylene composite film has developed rapidly, and it can be used for moisture preservation, gas barrier and cooking, and is used as a soft package for food and beverage.
Polypropylene pipes are used to transport hot water – PPR pipes, industrial wastewater and chemicals.
The plates are used to make containers. 3) Thermoformed products: The flakes are thermoformed into thin-walled products for use as a single-use food container-drinking cup. Others, such as blow molded products, are widely used in food packaging, such as yogurt containers, hot-filled beverage bottles. toy. Blocked polypropylenes with isotactic and random segments, respectively, can also be produced by special catalytic methods (metallocene catalysis). The properties of this polypropylene are similar to rubber.
