KEY BENEFITS OF ACETAL
Solvent, Fuel and Moisture Resistance
Acetal plastic’s resistance to solvents means it can be used in environments where other materials would break down or degrade. In addition, it’s highly resistant to fuels and moisture. This makes it an ideal material for use in harsh or challenging environments.
Suitable For Use in Moist Environments
Unlike other types of thermoplastic resins, acetal plastic is suitable for use in moist environments.Acetal plastic is resistant to water absorption and will not swell or soften when exposed to moisture. This makes acetal plastic an ideal material for food containers, medical implant devices and other applications where moisture resistance is essential.
Good Dimensional Stability
Good dimensional stability is a key benefit of acetal plastic. The material is resistant to changes in shape or size when exposed to temperature changes. This makes it an ideal choice for applications like medical implants and aerospace components. It is also approved for food contact applications.
Moderate Mechanical Strength and Stiffness
One of the most important properties of acetal plastic is its moderate mechanical strength and stiffness. This means it is strong enough to withstand high loads and stresses but not so strong that it is brittle and prone to breaking. Additionally, acetal plastic has a high resistance to chemicals and moisture, making it an ideal material for outdoor use.
Low Friction
Low friction is a term used to describe a material’s ability to resist sliding or rolling action. This resistance can be due to the material’s inherent properties, or it can be enhanced by adding special coatings or treatments. In either case, low-friction materials are prized for their ability to reduce wear and tear, minimise energy loss and improve the efficiency of machinery.Acetal plastic is one type of material that is renowned for its low-friction characteristics. This rigid, heat-resistant plastic is commonly used in high-load applications, such as gears, bearings and casters. Thanks to its low coefficient of friction, acetal plastic can help reduce wear and extend the service life of these critical components.
Excellent Properties in Wet and Dry Environments
Acetal is an engineering thermoplastic that has unique properties which allow it to perform in a variety of settings, especially those that are wet or dry. Unlike other plastics, which degrade in moisture-rich environments or become brittle and cracked when exposed to overly dry conditions, acetal holds its own no matter the humidity level. It can be used in many applications, from medical implants to car parts and everything in between. If you are looking for a material that will not let you down, no matter the conditions, acetal is a clear choice.
