The durability of polyurethanes can be influenced by several factors.
Here are some of the main ones:
Exposure to weathering: Prolonged exposure to the sun's UV radiation, temperature variations, humidity, weathering and other atmospheric agents can affect the durability of polyurethanes. These factors can cause the material to degrade over time, leading to the loss of mechanical properties and the appearance of cracks, discolouration or deterioration.
Mechanical loads: The use of polyurethanes in applications subject to mechanical loads or stresses may affect their durability. Excessive loading, impact, abrasion and other mechanical stresses can cause wear, deformation or damage to the material, reducing its durability.
Chemical conditions: Exposure to aggressive chemicals, such as solvents, oils, acids or bases, can affect the durability of polyurethanes. Some chemicals may cause chemical deterioration, swelling, deformation or alteration of material properties.
Material and formulation quality: The quality of the polyurethane and its formulation directly influence its durability. High quality polyurethanes and formulations specific to a particular application tend to have greater durability than lower quality materials or less suitable formulations.
Maintenance and care: Proper maintenance and care of polyurethane products can contribute to their durability. Regular cleaning, UV protection, proper handling of mechanical loads and avoiding exposure to harmful chemicals can extend the life of polyurethanes.
Conditions of use: Conditions of use, such as temperature, humidity, surroundings and intensity of use, can affect the life of polyurethanes. Extreme conditions or aggressive environments can accelerate degradation of the material.
It is important to consider these factors when selecting polyurethanes for a specific application and to take appropriate preventive and maintenance measures to ensure durability and performance over time.
