Polymers used in computers
WebDec 5, 2024 · A polymer is a chemical compound with molecules bonded together in long, repeating chains. Because of their structure, polymers have unique properties that can be tailored for different uses. Polymers are both man-made and naturally occurring. Rubber, for example, is a natural polymeric material that has been used for thousands of years. WebIt boasts a hardness range from 30 to 85 Shore D, along with excellent tear resistance and flex fatigue for use in memory card slot doors. Due to its particularly good adhesion to PC or PC/ABS, Hytrel® can also be used in overmolded grips and protective edges. The material has also attracted interest in cables.
