What are the upstream raw materials of PP non-woven fabrics? What do the downstream products contain?

PP non-woven fabrics have a wide range of applications in the field of chemical production raw materials, and their upstream and downstream related items are numerous. The following are some of the main upstream and downstream related items:



1. Upstream related items:(1) Polypropylene(PP): The main raw material of PP non-woven fabric is polypropylene, which is a thermoplastic resin with excellent chemical resistance, heat resistance, electrical insulation and mechanical characteristics. The manufacturing process of polypropylene mainly includes slurry method, fluid bulk method and gaseous phase method. The performance of polypropylene produced by different processes is different, so it's necessary to select suitable polypropylene raw materials according to the production standards of non-woven fabrics. According to research(2) Additives: In order to enhance the performance of PP non-woven fabrics, it's necessary to add some auxiliary materials, such as antioxidants, anti-ultraviolet agents, hydrophilic agents, flame retardants, etc. In fact The type and amount of these additives need to be determined according to the specific consumption of the nonwoven fabric. I've found that

2. You know what I mean?. From what I've seen, First Downstream related items:(1) Medical and health items: PP non-woven fabrics have good atmosphere permeability, filtration and antibacterial characteristics, so they're broadly applied in medical and health fields, such as surgical gowns, masks, dressings, sanitary napkins, etc. But(2) Filter material: PP non-woven fabric has high filtration efficiency and low resistance, and is able to be applied in atmosphere filtration, fluid filtration and other fields, such as atmosphere purifier filter elements, oil filters, etc. But For example(3) Packaging material: PP non-woven fabric has excellent strength and toughness, and is able to be applied to package various items, such as food, medical equipment, etc. From what I've seen,(4) Agricultural cloth: PP non-woven fabrics is able to be applied in the agricultural field, such as moisturizing cloth, shade cloth, etc. In particular, which is able to enhance the development efficiency and yield of crops. In short, the upstream and downstream related items of PP non-woven fabrics are very extensive, involving medical and health, filtration, packaging, agriculture and other fields.
