PM606 POLYMER TESTING METHODS
UNIT I
Standards and Specimen Preparation: Standards and specifications and their importance with reference to polymers.
Preparation of test specimen by various techniques for thermoplastics, thermosets, and elastomers. Conditioning and test atmospheres.
UNIT II Mechanical properties: Tensile, compression, flexural, shear, tear, impact, abrasion, hardness, permanent set, resilience, flex and cut growth resistance. Creep and stress relaxation.
UNIT III
Thermal Rheological Properties: Transition temperatures, melt flow index, Vicat softening temperature, heat distortion temperature, coefficient of expansion, specific heat, thermal conductivity, shrinkage, brittleness temperature, thermal stability, and flammability.
Plasticity, viscosity (plastimeter, Mooney viscometer, ODR, MPT, capillary rheometer, and torque rheometer)
UNIT IV Electrical, Optical and other Properties: Volume and surface resistivity, dielectric constant and power factor, dielectric strength, arc resistance, tracking resistance.
Refractive index, transparency, haze, gloss clarity, and birefringence.
Environmental stress crack resistance (ESCR) - water absorption, weathering and chemical resistance, aging, ozone resistance, permeability, adhesion.
UNIT V
Testing of Products: Plastic films, sheeting, pipes, laminates, foams, containers, and cables. Rubber hose, MC sheet, wire and cables, foams, gloves, tyres and tubes.
