Important considerations

Pros

  • High Durability - Acetal is highly durable and resistant to wear and tear, making it an ideal choice for parts that will experience a lot of wear and tear over time.
  • Chemical Resistance - Acetal is resistant to a wide variety of chemicals, making it an ideal choice for parts that need to resist corrosion or exposure to harsh chemicals.
  • Low Coefficient of Friction - Acetal has a very low coefficient of friction, making it ideal for low-friction applications such as bearings and gears.
  • High Strength - Acetal is strong, yet lightweight, making it an ideal choice for parts that need to be both durable and lightweight.
  • Low Water Absorption - Acetal is highly resistant to water absorption, making it ideal for parts that need to be in contact with water for long periods of time.
  • Good Electrical Properties - Acetal is a good electrical insulator, making it an ideal choice for parts that need to be electrically insulated.
  • Low Cost - Acetal is generally inexpensive compared to other materials, making it an ideal choice for cost-sensitive applications.

Cons

  • High Cost: Acetal is a relatively expensive material, so buyers should consider the cost when evaluating it for an application.
  • Limited Color Options: Acetal is only available in white and black, while other materials such as PVC and Polypropylene come in a variety of colors.
  • Low Temperature Resistance: Acetal is not suitable for applications that require exposure to temperatures above 200 degrees F (93 degrees C).
  • Low Chemical Resistance: Acetal is not resistant to most chemicals, including strong acids and bases.
  • Stiffness: Acetal is a relatively stiff material, which may limit its use in applications that require flexibility.

Trivia

An interesting fact about Acetal is that it is one of the few polymers that is capable of being injection molded. This means that it can be used to make complex parts, like those found in medical devices, automotive parts and electronics. Acetal is also popular with designers due to its low coefficient of friction, making it ideal for mechanical parts that require low friction in order to move or rotate properly. Additionally, Acetal is a very stable polymer, making it ideal for applications that require a material that will not degrade over time. Source: Professional Plastics.
