PP Phillips Flat Head Screws

PP (Polypropylene) is a thermoplastic polymer with the following properties and characteristics:

1. Good chemical resistance: PP is resistant to acid, alkali, salt, and other chemicals and can work stably in high temperatures, high pressures, and harsh environments. Therefore, PP is widely used to make corrosion-resistant containers, pipelines, and so on.

2. Good UV and oxidation resistance: PP is highly resistant to UV and oxidation, can be used outdoors for a long time, and is not quickly aged or yellowed. Therefore, PP is widely used to produce outdoor products, construction materials, etc.

3. Good thermal stability and mechanical properties: PP has good thermal stability, rigidity, and toughness. Its high melting point can be maintained at high temperatures to stabilize its performance, so it is widely used in the production of high-temperature-resistant parts and structural components. At the same time, PP has good mechanical properties with high tensile and impact strength, suitable for making high-strength products.

4. Low density, lightweight: PP's low density, specific gravity is only 0.91-0.93. It is light, easy to process, and suitable for making light products such as automobiles, airplanes, and so on. At the same time, its surface is smooth and easy to cut, stamp, injection mold, and use other processing techniques.

5. Can change the performance through additives: PP can be added through various fillers, plasticizers, antistatic agents, etc., to alter its performance so that it has a flame retardant, antistatic, antibacterial, enhancement, and other characteristics. For example, the addition of glass fiber can enhance the rigidity and strength of PP, the addition of carbon black can make PP with UV and anti-static properties, and the addition of antioxidants can extend the service life of PP.

Application areas:

1. Packaging industry: PP is widely used in the packaging industry, such as food packaging, cosmetic packaging, pharmaceutical packaging, etc. Plastic bags, boxes, bottles, etc., made of PP, have excellent heat-resistant, cold-resistant, oil-resistant, water-resistant, and other properties, which can protect the quality and safety of packaged goods.

2. automotive industry: PP has good abrasion resistance, rigidity, toughness, and other properties, and it is suitable for producing automotive shells, instrument panels, seats, etc. In the automotive industry, PP, made of automotive parts with high durability and lightweight advantages, is becoming increasingly widely used.

3. medical devices: PP has good chemical resistance, transparency, and other properties, making it suitable for the production of medical supplies, infusion bottles, etc. PP used in medical equipment has a high degree of hygiene and safety, making it widely used in the medical industry.

4. household goods: PP-made furniture, storage boxes, shoe boxes, etc., with heat resistance, durability, lightweight, etc. PP-made home furnishings are safe, environmentally friendly, and in line with the needs of people's home lives.

5. Electronic industry: PP used in battery boxes, cable casings, TV housings, etc., has good insulation properties and is highly resistant to temperature change.
