FAQ's of Polyurethane Rod:

Q: How is polyurethane rod manufactured and what is its typical shaping mode?

A: Polyurethane rods are produced using extrusion molding, a process wherein thermoplastic polyurethane (TPU) is shaped while heated. This method ensures uniformity, smooth surface finish, and consistent quality throughout the rod.

Q: What applications are best suited for polyurethane rods with these specifications?

A: These rods are ideal for engineering, automotive, mining, and industrial machinery applications where high abrasion resistance, excellent impact toughness, and chemical resistance are required. Their electrical insulation and UV resistance make them suitable for varied environments.

Q: When should I choose polyurethane rods over other materials?

A: Polyurethane rods are preferred over metals or conventional plastics when impact strength, flexibility (elongation at break 300%-600%), abrasion resistance, and resistance to oils or solvents are essential. They perform well in environments with temperatures ranging from -35C to +80C.

Q: Where can these polyurethane rods be utilized in an industrial setting?

A: These rods find use in bushings, rollers, liners, spacers, and insulation pads across multiple industries, including manufacturing plants, automotive workshops, mining operations, and heavy equipment assembly lines.

Q: What is the benefit of minimal water absorption and good electrical insulation?

A: Minimal water absorption minimizes swelling and degradation, preserving the rod's mechanical properties over time. Good electrical insulation ensures safety and functionality in electrical or high-voltage environments.

Q: How should polyurethane rods be stored for optimal longevity?

A: To maintain their performance characteristics, store polyurethane rods in a dry, cool place away from direct sunlight and sources of high heat, which helps avoid premature aging and ensures material integrity during storage.
