Exploring the Benefits and Applications of Thermoplastic Extrusion
Many demanding industries require thermoplastics due to their various advantageous properties. From their durability to their chemical resistance, and more, these polymers are chosen very carefully for each product and application to ensure all of the product’s desired properties are accounted for. In this blog, we will review the benefits and applications of thermoplastic extrusion.
What Are Thermoplastics?
Thermoplastics are polymers that can be softened through heating and can be processed through extrusion and other manufacturing methods. These plastics show no changes in chemical composition or properties when they are cooled and hardened, allowing them to be processed as needed without having to worry about losing desirable properties. The most common thermoplastics on the market include polyethylene, polypropylene, polystyrene, and polyvinyl chloride (PVC).
What is the Thermoplastic Extrusion Process
The process of thermoplastic extrusion is no different than extrusion for traditional plastics. To begin, the thermoplastic granules are fed into the hopper of the extrusion machine. These granules are then fed into the extruder where they are melted in a heated chamber. The melted thermoplastic is forced through a die that is the shape of the finished product. As the plastic cools, it takes the desired shape of the final product.
Benefits of Thermoplastic Extrusion
Thermoplastic extruded products offer many benefits making them ideal for a wide range of applications and industries. Some of the most notable benefits of thermoplastic extrusion include:
Durability
Since thermoplastics are elastic and flexible, these polymers are highly resistant to impact — more so than traditional plastics.
Chemical Resistance
Thermoplastics are generally resistant to many chemicals, including acids, bases, and other types of chemicals, making them ideal for use in a wide range of applications.
Biocompatibility
Since thermoplastics are biocompatible, they do not break down in the body, nor do they interact with the body in negative ways.
Recyclability
Since thermoplastics can be reheated and remolded various times without losing their properties, they can be recycled and reused repeatedly.
Can Be Blended with Additives
When blended with additives, some of the properties of thermoplastics can be changed to make them more desirable for certain applications. For example, thermoplastics can be blended with additives to meet smoke, flammability, and toxic gas release requirements.
Thermoplastic Applications
With so many advantageous properties, thermoplastics can be used in a wide range of applications.
Medical
Due to their durability and biocompatibility, thermoplastics are commonly used to manufacture medical devices and tubing.
Construction
Pipes for waste, water, and sewage, flooring, and siding are created from thermoplastics due to their chemical resistance and durability.
Office Furniture
Office furniture needs to be durable and attractive since it is used constantly. With thermoplastics being used for chairs and desks, they are able to withstand constant use.
Lighting
Casings and housings for lighting and cable insulation are created using thermoplastics because of their durability.
