Plastics are a wide range of semi-synthetic or synthetic substances that contains polymers as their main ingredient. The plasticity during production enables the plastic to be moulded, extruded or pressed into solid objects of different shapes. It is …
Stress, strain and modulus are related to each other by the following equation. The modulus or stiffness of a material can be determined when the material is loaded in different ways, such as tension, compression, shear, flexural (bending) or torsion (twisting).
Plastic - Polymers, Synthetic, Recycling | Britannica
2024年10月17日 · As mentioned above, polymers that are classified as plastics can be divided into two major categories: thermoplastics and thermosets. Thermoplastics such as polyethylene and polystyrene are capable of being molded and remolded repeatedly. Thus, a foamed-polystyrene cup can be heated and reshaped into a new form—for instance, a dish.
