Investigation Into the Tg of Foams
Investigation Into the Tg of Foams
25 Jan 2016This application note describes an experiment on a polyurethane foam. The sample was investigated in compression mode of the PerkinElmer® DMA 8000 as it is relatively soft. The Tg was observed in the modulus and tan δ data. The glass transition of polyurethane is especially important, depending on its usage, as in normal applications like packaging or furnishings it needs to be in its rubbery state to provide the desired characteristics.

Mechanical TestingMechanical testing explores the elastic and inelastic nature of a material when force is applied. A mechanical test shows whether a material is suitable for its intended application by measuring hardness, tensile strength, elongation, elasticity, and fatigue limit.Non-Destructive TechniquesNon-destructive techniques (NDT) describes a variety of analytical techniques used to evaluate the properties of a material. Common methods include ultrasonic, magnetic-particle, liquid penetrant, radiographic, remote visual inspection (RVI), and eddy-current testing. NDT is regularly used in forensic engineering, civil engineering, mechanical engineering, electrical engineering, systems engineering, aeronautical engineering, and medicine.Polymeric MaterialsPolymeric materials are widely used in industries ranging from biomedical devices to packaging and electronics. Research into these materials focuses on their properties, including strength, flexibility, and degradation. Advances in polymer science have enabled the development of more sustainable and high-performance materials.
