Be on the lookout for your Britannica newsletter to get trusted stories delivered right to your inbox. The chemical properties of polypropylene are such that polypropylene does not react with diluted bases and acids, which are often found in liquids, first-aid products, and cleaning agents. The fiber is sensitive to heat and light, but the resistance to these agents can be influenced by added stabilizers. Polypropylene fabric is a term used to describe any textile product that is derived from the thermoplastic polymer polypropylene. It is slightly more prone to oxidation than polyethylene unless appropriate stabilizers and antioxidants are added. Polypropylene is a type of thermoplastic polymer resin. Propylene is a gaseous compound obtained by the thermal cracking of ethane, propane, butane, and the naphtha fraction of petroleum. (Its melting point is approximately 170 °C [340 °F].) … Chemical Properties: PP is resistant to fats and almost all organic solvents when it is at room temperature. The chemical structure of the propylene molecule is CH2=CHCH3. Physical Properties Amorphous Density: 0.85 g/cm3 [1] Crystalline Density: 0.95 g/cm3 [2] Melting Point of 320°F (160°C) Doesn’t Soak up water (good for uses around moisture) Chemical Properties Very strong against corrosion; doesn’t react with chemicals like alkaline substances, acids, etc. In fact, it’s second only to polyethylene in volume. Automotive Applications: Polypropylene is widely used in automotive parts because of its low cost, weldability, and mechanical properties. The excellent optical clarity … Polypropylene is one of the most common plastics used worldwide. Amazon Doesn't Want You to Know About This Plugin. Numerous industrial end uses exist as well, including rope and cordage, disposable nonwoven fabrics for diapers and medical applications, and nonwoven fabrics for ground stabilization and reinforcement in construction and road paving. Typical Engineering Properties of Polypropylene. In short, it is a very useful type of plastic, with numerous commercial, industrial, and fashion applications. The absence of any real need for high molecular weight, from the mechanical properties view point, leads … Consumer Products. Properties of Polypropylene Fibers The raw material of polypropylene is derived from monomeric C3H6 which is purely hydrocarbon. The properties of polypropylene that make the plastic a popular choice for products include the lightweight nature of the material and its high tensile strength. With its balance of chemical, thermal and electrical properties and good strength-to-weight ratio, this thermoplastic material is suitable for many applications. During the production phase, polypropylene can be combined with other materials, such as rubber, to alter its properties.
