What causes rubber bands to deteriorate? Most elastomers undergo rubber degradation over time and the most common rubber deterioration causes are exposure to light, oxygen (ozone) and heat. Oxidative and thermal ageing of rubber are accelerated by stress and reactive gases, like ozone, resulting in cracking, charring and colour fading. How long does rubber last? […]
What is Polarisation and its types?
What is Polarisation and its types? Polarization (also polarisation) is a property applying to transverse waves that specifies the geometrical orientation of the oscillations. In linear polarization, the fields oscillate in a single direction. In circular or elliptical polarization, the fields rotate at a constant rate in a plane as the wave travels. What is […]
