When considering a plastic compound to use for a custom machined part and a specific application, some typical properties to evaluate are temperature, impact strength, and wear resistance. Thinking about how much water a plastic component can absorb might not come immediately to mind.
Plastics today are used in almost unlimited number of applications, many of which were previously handled by metal components, especially when the application required the part to be exposed to harsh conditions such as temperature extremes. Today’s modern plastic formulations are superior in many ways to previous generations of plastic materials; however, they come in a wide range of compounds and not all plastics are suitable for all applications. Every plastic formulation has its own unique characteristics, such as durability, tensile and impact strength, temperature range, and more.
Unlike metals or ceramics, plastics are viscoelastic materials – that is, they respond to stress as if they’re a combination of a viscous fluid and a plastic solid. In other words, while plastics have solid-related characteristics such as stability of form, strength — and, yes, elasticity — they also possess fluid-like properties such as flow, which can be affected by temperature, rate, and time as well as the amount of loading.
Plastic compounds come in a staggering array of formulations and materials for a wide range of industries, applications, and products. Selecting the right plastic material that offers excellent heat resistant properties is critical for any application in which thermal properties can be adversely affected by the environment.
