Why is thermoplastic used

The thermoplastics , with the exception of polyester and polyimide film, have only recently gained popularity, particularly for microelectronic structures in the recent times, Advanced thermoplastics can now provide high melting points and exceptional stability early generation polymers could not offer.

Many thermoplastic materials, especially the composites, tend to fracture rather than deform under high-stress levels, They suffer from creep where the thermoplastics materials relax or weaken when they exposed to long-term loading. Thermoplastics are more expensive than thermoset materials and they c an melt if they heated, Many materials have poor resistance to hydrocarbons, organic solvents and highly polar solvents but the others have excellent resistance to these materials.

Thermoplastics often used for manufacturing include polyvinyl chloride PVC , polyethylene PE , and polystyrene PS , often used in packaging. Some common thermoplastic materials used include;. Thermoplastic waste is reusable — Instead of discarding the waste that occurs during the injection molding process, thermoplastic materials can be recovered and re-melted for future use.

They are a higher-yield choice of material — Due to their recoverability, you will see a high piece yield from your overall stock of material. The material recycles well — Thermoplastic materials are suitable for recycling since they are easily melted.

They are great for prototyping — Because the main purpose of prototypes is to test the function of products, making use of a material that is reusable is ideal. After the prototype has been tested, the plastic can be melted and re-molded for another prototype or for production. Thermoplastics are suitable for high-impact applications — Their molecular qualities make them ideal for application areas that require high-stress resistance and strength.

Suitable for thin-wall uses — Their strength and flexibility make thermoplastics one of the best choices for applications that need high-tensile strength as well as thin wall thicknesses. And these benefits have huge implications for human safety and environmental protection. If the thermoplastic components of the braking system of a Boeing fail prematurely, or gas and oil pipelines leak, the consequences can be catastrophic.

While alternatives to thermoplastics do exist, they will have different design, cost, durability, and weight considerations, which often render them a less optimal choice.

From durability to chemical resistance, thermoplastics have a lot going for them. Elastomers can be better in terms of dynamic fatigue and resilience, may be easier to process into some desired shapes, and may therefore be less expensive to produce. Material selection is always about finding the right balance among many different properties, and avoiding or minimizing compromise in finding the right material for the job.

Good material scientists and design engineers can help you determine the right material properties you need based on where, for how long, and in what conditions your part needs to perform. Have questions about choosing the right material for your next project?
