Dysgeusia (/dÉªsËÉ¡uËÊÉ/ or /dÉªsËÉ¡juËziÉ/) or parageusia is a distortion of the sense of taste. Dysgeusia is also often associated with ageusia, which is the complete lack of taste, and hypogeusia, which is the decrease in taste sensitivity. An alteration in taste or smell may be a secondary process in various disease states, or it may be the primary symptom.
There are two main types of plastics â. Thermoplastics which are softened by heat and can be moulded. (Injection moulded, blow moulded or vacuum formed). Good examples are acrylic, polypropylene, polystyrene, polythene and PVC. Thermosets which are formed by ha heat process but are then set (like concrete) and cannot change shape by reheating.
Plastic is made of monomers. Organic plastics are polymers, composed of monomers (repeating units). A polymer is a chain of molecules repeated again and again.lastics are made of many repeating units of monomers to form a long chain known as a polymer. Different types of plastics have different monomers. Examples of polymers that â¦ are plastics include polyvinyl chloride (PVC) and polystyrene.
