Polypropylene is a thermoplastic that belongs to the polyolefin group of materials. Like most polyolefins, polypropylene is approved for direct food contact. Polypropylene offers a great combination of physical, chemical, mechanical, thermal, and electrical properties, with a good strength to weight ratio. Flexural Modulus, sometimes referred to as the bending modulus, is the tendency of a material to bend. It is the ratio stress to strain in a flexural deformation and is expressed in units of force per area. ASTMD790; Flexural Strength is the ability of a material to resist deformation under load.

This test measures the flexural strength and modulus of plastics. Polypropylene (PP) is a member of the environmentally-friendly polyolefin family. Like its sister, HDPE, polypropylene’s electrical properties, chemical and temperature resistance making polyproylene sheets a terrific choice for many industrial applications.
In mechanics, the flexural modulus or bending modulus is an intensive property that is computed as the ratio of stress to strain in flexural deformation, or the tendency for a material to resist bending. It is determined from the slope of a stress-strain curve produced by a flexural test (such as the ASTM D790), and uses units of force per area. Earth-friendly High Density Polyethylene (HDPE) is a durable polyolefin, resistant to most solvents and temperature variation. FDA-approved for food contact! Grafix stocks many sizes and finishes of HDPE sheets and can customize for your color, thickness and finishing needs. Flexural Properties of Unreinforced and Reinforced Plastics and Electrical Insulating Materials1 This standard is issued under the ﬁxed designation D 790; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision.
For sheets (w >> h) and fibres (w~h) the effective modulus under bending is (almost always) higher than the Young's modulus. With uniform isotropic materials the flexural modulus for a structure can readily be calculated fron the Youngs modulus and Poisson's ratio [it is approximately E/(1-ν 2) for a sheet]. However, manufacturing methods mean ... This fifth edition cancels and replaces the fourth edition (ISO 178:2001), which has been technically revised to harmonize it with ISO 527-2  with respect to the test speeds used for the determination of the flexural modulus and for the determination of other flexural properties. Axpoly ® recycled polypropylene pellets. Axpoly ® recycled polypropylene is a high performance black/grey copolymer. It is available in a range of grades suitable for injection moulding of complex-shaped components, such as drainage goods or storage boxes, and for many types of profile extrusion applications.
Polypropylene is an economical material that offers a combination of outstanding physical, chemical, mechanical, thermal and electrical properties not found in any other thermoplastic. Compared to low or high density polyethylene, it has a lower impact strength, but superior working temperature and tensile strength.
