AQA Product Design Practice Exam

Thermoplastic elastomers (TPE) are widely used in product grips due to their unique combination of flexibility and durability, which provides an excellent tactile feel and comfort when held. TPEs can be easily processed using standard plastic manufacturing techniques, making them versatile for production. They offer good resistance to chemicals and varying temperatures, ensuring the grips maintain their performance and aesthetics over time. Additionally, TPEs are available in various formulations, allowing manufacturers to customize the hardness and texture to enhance the grip feel.

While other types of elastomers, such as thermosetting elastomers or rubber elastomers, may have specific applications depending on the context, TPEs remain favored in product grips because they achieve an optimal balance between performance, ease of manufacturing, and user comfort. Polyurethane elastomers also have applications due to their strength and abrasion resistance, but TPEs are more commonly recognized for everyday product grips because of their processing advantages and flexibility in design.
