Which Plastic Materials Are Suitable For High-temperature-resistant Home Appliance Components?

General-purpose heat-resistant plastics for home appliances
PP (Polypropylene): With a melting point of 167°C, it is the only general-purpose plastic suitable for microwave use; commonly used for microwave-safe food containers, rice cooker inner pot supports, and similar components.
PC (Polycarbonate): Suitable for long-term use at approximately 120°C and short-term exposure up to 130°C; offers high transparency and is commonly used for transparent electric kettle bodies, high-temperature viewing windows, and similar parts.

 

Engineering-grade heat-resistant plastics for home appliances
PA46 (Nylon 46): Capable of long-term operation at 135°C; features high crystallinity and excellent toughness; commonly used for structural components such as appliance motor parts and high-temperature gears.
PSU (Polysulfone): Suitable for long-term use at 150°C and short-term exposure up to 180°C; offers excellent overall electrical properties; commonly used for high-temperature sterilization components and structural parts in coffee machines.
PVDF (Polyvinylidene Fluoride): Withstands long-term temperatures of 150°C and offers outstanding corrosion resistance; commonly used for high-temperature seals and anti-corrosion components in water heaters.
