What material are Plastic Seat Shells thermoformed?
Plastic seat shells are typically thermoformed from a variety of materials, each with its own advantages and disadvantages. Here are some of the most common:
- Acrylonitrile butadiene styrene (ABS): This is a strong, impact-resistant plastic that is often used for chair shells because it can withstand a lot of wear and tear. It is also relatively inexpensive and easy to work with.
- High-impact polystyrene (HIPS): This is a less expensive option than ABS, but it is not as strong or durable. It is often used for chairs that are not expected to see a lot of use, such as those in waiting rooms or cafeterias.
- Polypropylene (PP): This is a lightweight, flexible plastic that is often used for outdoor furniture because it is resistant to weather and UV rays. It is also relatively inexpensive and easy to recycle.
- Polycarbonate (PC): This is a very strong and durable plastic that is often used for high-end furniture or applications where safety is a concern, such as in children’s furniture. It is more expensive than other options, but it is also very clear and can be polished to a high gloss.
The specific material that is used for a particular chair shell will depend on the intended use of the chair, the desired properties of the material, and the cost.
