When selecting a thermoplastic polymer for manufacturing or other crucial uses, business owners need to consider several factors. Here are some of them:
Mechanical properties
Different thermoplastic polymers have diverse mechanical properties. For instance, tensile strength and modulus of elasticity suitable for various tasks. If the business targets a task that requires high strength, durable materials, such as frames and structural components, it should settle for ABS, polycarbonate, or polyamide. At the same time, materials such as polyetherimide and nylon possess good elongation and tensile, making them suitable for manufacturing goods. Moreover, polymers such as Polymethyl Methacrylate and nylon-6,6 have high-impact resistance. Hence, they can be used to manufacture products that require long-term use.
Thermal properties
Every thermoplastic polymer has a specific temperature range in which it can be practically used. Therefore, business owners should ensure they get a material that can endure the required temperature. For example, polyethylene is ideal for low temperatures, while polycarbonate and polyphenylene can be used in high-end applications that require a material that can withstand high temperatures.
Chemical environment
In most cases, thermoplastics are likely to be exposed to different chemicals, especially in manufacturing. Therefore, business owners should look for a material that can withstand chemicals used in making manufactured goods. For instance, polypropylene is resistant to caustic chemicals, while fluoropolymers are resistant to solvents and acidic chemicals.
Processing requirements
Ideally, thermoplastics commonly differ in their melting temperatures. Due to this, some are easier to fabricate than others. Hence, when selecting a polymer, bear in mind the manufacturing method. For example, injection molding and 3D printing require different materials. So, ensure the thermoplastic matches the production technique intended.
Application-specific requirements
Business owners should also consider the specific features needed for certain applications. For instance, polycarbonate is suitable for windows and safety glasses due to its high transparency and optical clarity. At the same time, polyether ether ketone is ideal for electrical components, automobile parts, and aerospace applications, as it can withstand extreme conditions.
The good thing about plastics coverings is that they do not require a lot of maintenance to stay in good condition. To begin with, one ought to wash the surface regularly using warm water and a mild detergent. Avoid using chemicals that are likely to damage the surface finish or affect the material's properties. In addition, donning a thermoplastic cover is resistant to many forms of damage, but sharp objects might scratch it. Therefore, one should carefully check the surface for any cuts or dents before and after use. If there are any, ensure they are fixed. Also, to enhance durability, it's essential to store the polymer in a location with low exposure to heat, dust, or high humidity.
Yes, some modern thermoplastic materials can be manufactured in an eco-friendly manner. This is especially when using bio-based materials or recycled feedstock. Moreover, the recyclability of some thermoplastics also contributes to their sustainability.
Buyers can educate themselves on various tips to prolong the lifespan of thermoplastics. To begin with, they should expose the material to weather, especially the sun, for long hours. In addition, they should regularly wash the surface using warm water and a mild detergent. Also, they should avoid placing hot items directly onto the polymer surface.
First, as mentioned previously, a business owner should choose a thermoplastic that meets the requirements for the intended use. Therefore, they should consider the thermal and chemical resistance of various materials. In addition, they should look for polymers with high tensile strength, elongation, and impact resistance. They can settle for polymers such as polycarbonate, polypropylene, and nylon-6,6. Moreover, opting for reinforced variants of these thermoplastics can further enhance durability.
