When it comes to demanding industrial applications, material performance is key. Parts need to endure punishing environments, like exposure to extreme temperatures and harsh chemicals, while maintaining their integrity. That’s why many manufacturers turn to engineering thermoplastics to ensure product longevity or reliable equipment functionality. These versatile materials can outperform metals and traditional plastics in durability and efficiency.
What Is Thermoplastic Material?
Thermoplastic materials are polymer resins that become soft and moldable when heated and then harden as they cool. This process is reversible and repeatable, however, which means that manufacturers can reshape and remold thermoplastic materials several times without altering their chemical structure.
Unlike thermoset plastics, which undergo a chemical change and harden permanently after curing, thermoplastics become homogenized liquids that retain their ability to be reprocessed. This physical rather than chemical change makes them ideal for both custom fabrication and sustainable reuse. Numerous types of thermoplastics are available to manufacturers, each with its own:
- Crystalline structure
- Material composition
- Density
- Beneficial material properties
Benefits of Using Engineering Thermoplastics in Industrial Applications
Engineering thermoplastics offer the industrial sector myriad benefits for manufacturing products.
Longevity and Sustainability
Unlike single-use consumer plastics, engineering thermoplastics are designed for durability. These materials are energy efficient to manufacture and lend your products extended lifespans, even in high-friction or chemically harsh environments. Many thermoplastics can also be recycled, lessening the burden on important resources and making them a more sustainable alternative to some metals or thermosets.
Electrical/Thermal Insulation and Flame Ratings
For electrical applications or those that expose parts to extreme temperatures, thermoplastics excel as fire-resistant electrical and thermal insulators. They offer high dielectric strength and can be manufactured to meet UL 94 V-0 flame ratings. Their ability to manage heat and prevent electrical conductivity makes them ideal for switchgear, enclosures, and other electronic housings.
Temperature Resistance
That said, manufacturers can formulate thermoplastic materials to either insulate against or conduct heat, depending on your application and heat transfer needs. Thermoplastics are known for their excellent thermal resistance. High-performance materials like PEEK and PTFE can withstand both cryogenic and high-heat conditions without deforming.
Chemical Resistance
Advanced thermoplastics offer excellent resistance to acids, alkalis, and solvents, making them ideal for industries like food processing, medical manufacturing, and chemical handling. This chemical stability helps maintain products’ structural integrity in environments where metals might corrode or degrade.
UV Resistance for Outdoor Use
Outdoor applications present a unique challenge, with materials exposed to prolonged sunlight. To address this, you can select thermoplastics enhanced with UV-resistant additives to protect against degradation. Materials such as HDPE, PTFE, and PEEK are excellent choices for components that must withstand UV radiation and external use.
Reduced Wear on Mating Parts
Thermoplastics help minimize wear on critical components that come into direct contact. Their low coefficient of friction helps protect mated parts made of aluminum and other soft metals. In many designs, thermoplastics serve as a sacrificial layer, preserving the life of more labor-intensive or costly components.
Self-Lubricating Properties
Certain thermoplastics can be engineered with self-lubricating additives that lower the need for ongoing maintenance. These materials minimize downtime by reducing the risk of mechanical failure due to friction or improper lubrication. Self-lubricating thermoplastics are advantageous for operations focused on reliability and total cost of ownership.
Weight Reduction and Enhanced Affordability
Typically, thermoplastics weigh roughly one-seventh the weight of steel. This reduction directly impacts product weight and the ease of installation and handling. Lighter components reduce the strain on lifting equipment, if any is needed at all. They also cut material and shipping costs and minimize vibrations and noise in dynamic systems. These advantages contribute to workplace safety and operational efficiency, as well.
Cost Savings Over Time
If you want long-term cost savings, thermoplastics are a good option. They’re easier to process, require less maintenance, and offer a longer lifespan than alternative materials. They also support lean manufacturing strategies by streamlining production and reducing system downtime and material waste, leading to measurable cost savings for manufacturers.
