HDPE has higher density therefore it has greater tensile strength
Young`s modulus of aluminum is about 70 GPa, or 10.3 x 106 psi.
Flexural strength is resistance offered against bending.Tensile strength is resistance offered against tensile force.
No the moment of resistance is a defining parameter that can be used to calculate the stress in a cross section of a given material that is subject to flexural loading. The ultimate flexural strength is a numerical value of stress at which the material will crack, tear, rip etc. Think about ultimate tensile strength and the value of Young's Modulus. Young's Modulus is not defined at the point of 'necking' and therefore the ultimate tensile strength cannot be computed from Young's Modulus and Hook's Law, but the UTS is an empirically defined value.
the compressive strength can be converted in to flexural strength by following formula of IS code 456-2000fcr=0.7^/- fck fcr= flexural strength fck= characteristic compressive strength in N/mm2

to ensure the design strength
Flexural Rigidity/strength and sectional modulus
HDPE has higher density therefore it has greater tensile strength
Plastics undergo a flexural strength test. The flexural strength test is used to determine the ability for a material to resist deformation under load.
the ability of beam or slab to resist failure in bending is called Flexural Strength of concrete.IIt is measured as modulus of rupture
it is the ratio of tensile strength to the flexural strength
Young`s modulus of aluminum is about 70 GPa, or 10.3 x 106 psi.
Flexural strength is resistance offered against bending.Tensile strength is resistance offered against tensile force.
Generally detergent bottle are made of high density polyethylene (HDPE) and polyethylene terephthalate (PET) depending on the detergent type if it is washing liquid or soap then PET is preferable due to its transparency properties. HDPE is more preferable for other type of detergents such as bleach, shampoo etc. and these products are highly chemical which requires a good chemical resistance. Therefore, HDPE has better properties for detergent container purposes; excellent flexural strength, good impact strength, very good chemical resistance, good fatigue resistance and service temperature to 126 °C. HDPE detergent bottles can be manufactured by extrusion blow moulding as it is suitable for mass production and cheaper than other techniques.
