What is PP and how did it develop?
PP is a thermoplastic addition polymer made from a combination of propylene monomers. Philip oil scientists Paul Hogan and Robert Banks first made polypropylene in 1951, and later Italian and German scientists Natta and Rehn also made polypropylene. Natta perfected and synthesized the first polypropylene commodity in Spain in 1954, and its crystallization ability aroused great interest. By 1957, polypropylene’s popularity had soared, and widespread commercial production began throughout Europe. Today, it is one of the most commonly used plastics in the world.
PP is often referred to as the steel of the plastic industry. As additives can be added to PP, the PP can be modified and customized to meet the unique application requirements. It can be easily copolymerized with other polymers to form composite plastics. Compared with pure PP, it can achieve more solid engineering applications. For example, Lida PP sheet, is composite, corrosion resistance, higher strength, wider application.
What are the characteristics of PP? Its most important features are as follows:
1. Chemical resistance: Diluted bases and acids do not react with PP, which makes it an ideal container for such liquids.
2. Elasticity and toughness: PP is elastic in a certain range of deflection, and early on deformation will undergo plastic deformation without rupture.
3. Fatigue resistance: The PP retains its shape after much bending.
4. Insulation: The PP material has a high resistance and is insulation.
What are the advantages and disadvantages of PP?
PP is easily accessible and relatively inexpensive, with high deflection strength, relatively smooth surface, moisture moisture and low water absorption. It has good chemical corrosion resistance in all kinds of acids and bases. At the same time, PP has good fatigue resistance and impact resistance strength, is a good electrical insulator. The disadvantage of PP is its high thermal expansion coefficient, which limits its high-temperature applications. It is also susceptible to UV influence and degradation, highly flammable and easy to oxidation.
Overall, PP is still a good material. It has unique mixing properties beyond other materials, making it ideal for many sheet ingredients. Choose a good sheet, please choose from Lida plastic industry.
