Ensuring proper food preservation and improving insulation and energy efficiency requires thermoplastic materials that retain their properties even at low temperatures. Designers in the refrigeration sector need high-performance materials to meet the demands of cooling systems and comply with energy consumption standards set by new environmental regulations.
Key Features of Thermoplastics for Refrigeration
Thermoplastics used in refrigeration must have specific characteristics to ensure optimal performance:
- High insulation capability: Essential for effective thermal insulation, reducing energy consumption, and eliminating condensation.
- Elasticity: Ensures sufficient flexibility and recovery for sealing components, such as gaskets.
- Impact resistance: Maintains durability even under repeated mechanical stresses at low temperatures.
- Food contact compliance: Guarantees safety for use in food-related applications.
- Chemical resistance: Withstands exposure to common cleaning agents and detergents.
- Recyclability: Supports a circular economy by being easy to recycle at the end of their lifecycle.
Recommended Thermoplastics
- Impact-resistant PVC: Ideal for maintaining performance at low temperatures and suitable for coextrusion with flexible materials.
- ABS: Excellent for applications requiring strength and flexibility.
- Thermoplastic elastomers (TPE): Flexible and durable, perfect for seals and gaskets.
- High-impact polystyrene (HIPS): Performs well at low temperatures.
- Polymethyl methacrylate (PMMA): Offers low-temperature resistance and superior transparency.
Risks of Using Inadequate Materials
The use of unsuitable thermoplastics in refrigeration systems can lead to several issues:
- Mechanical property degradation: Materials may become brittle, losing elasticity and compromising insulation.
- Increased rigidity: Especially in rigid plastics, low temperatures can reduce impact resistance.
- Temporary or permanent alterations: While some thermoplastics regain their properties after warming, significant mechanical stresses during cold conditions can cause irreversible damage.
The minimum operating temperature of a thermoplastic depends more on the mechanical stresses it endures than the temperature itself.
