This allows the material to withstand fairly heavy loads, despite being lightweight. in.
176° F. 8742K96. MatWeb's searchable database of material properties includes data sheets of thermoplastic and thermoset polymers such as ABS, nylon, polycarbonate, polyester, polyethylene and polypropylene; metals such as aluminum, cobalt, copper, lead, magnesium, nickel, steel, superalloys, titanium and zinc alloys; ceramics; plus semiconductors, fibers, and other engineering materials. Polypropylene Characteristics. Polypropylene is a kind of polymer which gets transformed into liquid when it is heated. And when frozen, it turns into a glassy state. Polypropylene (PP) is an economical material that offers a combination of outstanding physical, chemical, mechanical, thermal, and electrical properties not found in any other thermoplastic. PP HMS grades have a wide mechanical property range, high heat stability, good chemical resistance. The pseudoplastic nature of polypropylene enhances this effect at high shear rates (fast filling rates). At low temperatures of -70°C or lower, PP fibers remain their excellent flexibility. Rockwell R55. Weight: Polypropylene is a lightweight material. Polypropylene is a relatively easy materials to injection mould in spite of its semicrystalline nature. Polypropylene, High Melt Strength (HMS PP)– It is a long chain branched material, which combines both high melt strength and extensibility in the melt phase. THERMAL PROPERTIES. The absence of any real need for high molecular weight, from the mechanical properties view point, leads to low melt viscosity (easy flow). Polypropylene is a semi-clear white color by default, but can also come in opaque white on request. Tensile Strength. During the production phase, polypropylene can be combined with other materials, such as rubber, to alter its properties. Polypropylene is another material that is very hydrophobic (water-repelling); moreover, the polymer has no acidic or basic sites for the binding of dyestuffs. Hardness. 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. It is also spun into fibres for employment in industrial and household textiles. McMaster Part Number. Properties. At high temperature (below 120°C). Material Finish. Yield Strength (tensile) Elongation at Break. Polypropylene fabric is a nonwoven textile, which means that it is made directly from a material without any need for spinning of weaving. Typical Engineering Properties of Polypropylene General Properties English Units SI Units CAS Number 9003-07-0 9003-07-0 Density Homopolymer 3 Random Copolymer Impact Copolymer 3 TPOs 56.4 - 56.6 Lbs /ft 56.4 - 56.6 Lbs /ft3 3 56.0 – 56.2 Lbs /ft 3 54.6 – 56.1 Lbs /ft3 0.904 – 0.908 g/cm3 0.904 – 0.908 g/cm 0.898 – 0.900 g/cm Polypropylene has been considered important material for outdoor carpets, as it has a very high standard of light fastness. The properties of polypropylene that make the material popular include the non-toxic and non-staining nature of the plastic, and the relatively inexpensive cost of production.

2,500 psi. Material Properties Polypropylene. Compared to many materials, polypropylene’s structure has a good tensile strength—somewhere around 4,800 psi.

Those include the automotive sector, textiles, medical sector, consumer goods, and industrial applications. The main benefit of polypropylene as a fabric is its moisture transfer abilities; this textile cannot absorb any moisture, and instead, … This makes the plastic a very useful for use in products like food packaging. Density. The polymer that shows these properties is known as thermoplastic polymer. However, the material is susceptible to attack from oxidizing acids, chlorinated hydrocarbons, and aromatics. Polypropylene fibers have a softening point in the region of 150°C and a melting point at 160-170°C. With its balance of chemical, thermal and electrical properties and good strength-to-weight ratio, this thermoplastic material is suitable for many applications. Polypropylene is an economical material, and polypropylene products can be seen in every industrial and commercial application area today. *Homopolymer polypropylene. The polypropylene fibre does not have good resiliency as that of nylon.

Consequently, pigments are added to polypropylene melts prior to spinning.… Maximum Temp. Cost-effective and lightweight, polypropylene thermoplastic is easily welded, formed and machined.
PP fibers nearly remain their normal mechanical properties. Tensile strength: Its tensile strength is quite high. Polypropylene also has a strong resistance to cracking when placed under stress and a high level of impact resistance.

Polypropylene will resist many organic solvents, acids, and alkalines.
