PMP Flat Washers, available in sizes from M3 to M12, are crafted from Poly(methyl methacrylate) (PMP), also known as acrylic. These washers are designed to distribute the load of fasteners such as screws or bolts, protecting surfaces and providing a stable, secure fit. PMP is renowned for its excellent optical clarity, making these washers ideal for applications where transparency is important. The material also boasts high impact resistance, UV stability, and good chemical resistance, ensuring durability in various environments. PMP's low moisture absorption further enhances its suitability for use in both indoor and outdoor applications.

Metric Size – M3, M4, M5, M6, M8, M10, M12

Advantages of Using PMP Flat Washers:

Optical Clarity: PMP's transparency allows for an unobtrusive appearance, making these washers ideal for applications where visibility is key.

High Impact Resistance: The material's toughness ensures that the washers can withstand impacts without cracking, providing long-lasting performance.

UV Stability: PMP is resistant to UV radiation, preventing yellowing and degradation over time, which is particularly beneficial for outdoor applications.

Chemical Resistance: PMP washers resist a wide range of chemicals, including mild acids and alkalis, ensuring durability in various environments.

Low Moisture Absorption: The material absorbs minimal moisture, maintaining its mechanical properties and clarity even in humid or wet conditions.

Lightweight: PMP washers are significantly lighter than those made from metal, offering ease of handling and installation.

Specific Applications of PMP Flat Washers:

Electronics and Display Panels:

Used in securing components on transparent or semi-transparent electronic devices, where visibility and aesthetic appeal are important.

PMP Key Properties

  • Polymethylpentene (PMP) is highly valued for its exceptional transparency and low density, making it an ideal material for applications where clarity and lightweight properties are essential. PMP is one of the most transparent thermoplastics available, offering optical clarity that rivals glass. This makes it an excellent choice for applications such as medical devices, laboratory equipment, and food packaging, where visibility of the contents or components is important. Additionally, PMP’s low density contributes to its lightweight nature, which is beneficial in reducing the overall weight of products and improving ease of handling.

  • PMP also boasts excellent chemical and thermal resistance, making it suitable for use in environments where exposure to aggressive substances and high temperatures is common. PMP is resistant to a wide range of chemicals, including acids, bases, and solvents, which ensures that it does not degrade or lose its properties when in contact with these substances. Moreover, PMP can withstand elevated temperatures without significant loss of strength or dimensional stability, making it ideal for use in applications such as chemical processing, food sterilisation, and medical autoclaving, where both chemical exposure and high temperatures are factors.

  • Another key property of Polymethylpentene (PMP) is its low moisture absorption and excellent electrical insulation properties. PMP absorbs minimal moisture from the environment, which helps it maintain its mechanical properties and dimensional stability even in humid conditions. This makes it particularly suitable for use in applications where exposure to moisture is a concern, such as in electrical and electronic components. Additionally, PMP’s excellent electrical insulation properties make it an ideal material for insulating electrical parts and components, ensuring safety and reliability in electronic devices and systems. These properties, combined with its chemical and thermal resistance, make PMP a versatile material for a wide range of industrial and technical applications.
