PU, or polyurethane, is a type of elastomer used in the production of seals. It is a versatile material that offers excellent resistance to wear and tear, abrasion, and oil swell. PU seals can be used in a wide variety of applications, including hydraulic and pneumatic systems, automotive and industrial equipment, and consumer products.
One of the main advantages of PU seals is their high resistance to wear and tear, making them ideal for use in applications that involve frequent movement and high pressure. PU seals also have excellent tensile strength and elongation properties, which allow them to maintain their shape and function under a wide range of temperatures and pressures.
PU seals are resistant to a variety of fluids, including hydraulic oils, water, and some chemicals. They also have good resistance to ozone and weathering, which makes them ideal for use in outdoor applications. PU seals are typically used in low to medium pressure applications.
PU seals are available in a variety of sizes and shapes, including O-rings, U-cups, and custom shapes. They can be manufactured in a variety of hardness levels, ranging from soft and flexible to hard and rigid. The hardness of the The seal is determined by the amount of polyurethane used in its production.
Overall, PU seals are a reliable and cost-effective option for a wide range of sealing applications. They offer excellent durability, resistance to wear and tear, and compatibility with a variety of fluids, making them a popular choice in many industries.
