Polyester young's modulus
WebInitial modulus. Young’s modulus or the initial modulus (IM) is a measure of the amount of deformation that is caused by a small stress. Materials with a high modulus, often called stiff or hard materials, deform or deflect very little in the presence of a stress. Materials with a low modulus, often called soft materials, deflect significantly. Webabundance. The classical artificial fibres, e.g. polypropylene, polyacrylic, polyester etc, are hazardous to the environment. The main problems with synthetic polymers are that they are non-degradable and non-renewable. Since their invention, the use of these synthetic fibres has increased oil consumption significantly, and continues even today.

Webshows the range of E-modulus of TPU and RTPU in comparison to other materials. The modulus of elasticity (E-modulus) is determined by tensile testing according to DIN EN ISO 527-1A, using a test specimen at a testing speed of 1 mm/min. The E-modulus is calculated from the initial slope of the stress-strain curve as ratio of stress to strain.
