Each type of plastic material has distinct characteristics. Therefore, when selecting materials for a product, it's essential to choose the most suitable one based on the material's features and its intended use.
Before selecting a material, we need to understand the basic properties of various plastic materials to ensure we make the most appropriate choice for the finished product.
