      Limited Temperature Range: Latex washers, especially those made from natural latex, have a relatively narrow temperature range. They can degrade or lose their elasticity at higher temperatures, making them unsuitable for high-temperature applications such as certain automotive and industrial uses.

      Chemical Sensitivity: Although latex washers have good resistance to many chemicals, they are vulnerable to degradation by oils, solvents, and some chemicals. This reduces their effectiveness in applications involving exposure to harsh chemicals or oils, necessitating alternative materials like nitrile or fluorocarbon.

      UV and Ozone Degradation: Natural latex is susceptible to degradation from prolonged exposure to ultraviolet (UV) light and ozone, limiting the lifespan and effectiveness of latex washers in outdoor applications unless additional UV stabilisers are added.

      Mechanical Wear: Latex washers can wear out more quickly under mechanical stress, especially in applications involving high friction or constant movement. This shortens the maintenance intervals and increases the frequency of replacements in dynamic environments.

      Cost Variability: The cost of natural latex can fluctuate due to changes in the supply of raw materials, influenced by environmental and economic factors. This can affect the pricing stability of latex washers, making budgeting and cost management more challenging for manufacturers and consumers.

      Manufacturing Constraints: Producing latex washers with precise dimensions and consistent quality can be challenging, particularly for custom sizes and shapes. This may result in increased production costs and lead times, affecting the overall efficiency of the manufacturing process.

      Biodegradability Concerns: While natural latex is biodegradable, synthetic latex materials may not decompose easily and could contribute to environmental pollution. This raises environmental concerns, particularly for industries and consumers prioritising eco-friendly solutions.

      Compatibility Issues: Latex washers may not be compatible with certain substrates or surfaces, leading to poor adhesion or sealing performance. This requires careful selection and testing to ensure proper function in specific applications.

      Addressing these issues involves selecting the appropriate material for the specific application, considering alternative materials when necessary, and implementing design and manufacturing practices that mitigate these issues.
