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.

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.
Types of Flexible Plastic Tubing. Although we consider all of our plastic tubes to be flexible (more flexible than pipe), flexibility can be subjective. Polyurethane and PVC are the most flexible plastic tubing we produce.Polyurethane is also very abuse resistant and can withstand higher pressures when compared to PVC.We offer 4 different durometers (hardness) of Polyurethane exhibiting different characteristics.lastic Tubing & Flexible Tubing Products.
