What are some examples of thermoset plastics?

Examples of thermoset plastics include epoxy resins that are used for sealing and or adhering things together and urea formaldehyde, which is normally seen in pot handles or adhesives. Thermoset plastics are also found in polyester resin that is commonly used for mold castings or to bond materials. One of the most common thermoset plastics is the laminate counter tops that are commonly found in kitchens or work spaces.

These types of plastics can generally only be heated once to set them into the shape that is needed, and they are not generally recycled. The material starts out as liquid or some other malleable state. The material is exposed to high temperatures and molded or turned into adhesives.
