90-95 Shore a Hard Impact Resistant Polyurethane Rod

PU rods have more balanced comprehensive performance. Their wear resistance is 3-5 times that of rubber and more than 2 times that of nylon, with far better resilience, toughness and compression deformation resistance, avoiding permanent deformation and cracking under long-term stress. Ordinary rubber is prone to aging, poor wear resistance and low load-bearing capacity; nylon has fixed hardness, insufficient toughness and is easy to crack. In contrast, PU rods support customizable hardness, bal

Full customization is supported. The hardness can be customized from Shore A10 to Shore D75. Conventional diameters range from 5mm to 200mm, and non-standard large/small diameters, extended lengths, hollow and solid structures are all available. Special colors, anti-static and high/low temperature resistant properties can also be customized, with precision deep processing such as turning, drilling and cutting according to drawings.

The stable working temperature of conventional products is -40 to 80. Within this range, it maintains stable elasticity, hardness and dimensional accuracy without softening, embrittlement or deformation. Long-term over-temperature use will accelerate material aging and shorten service life. It can maintain good toughness and avoid cracking in low-temperature environments, suitable for outdoor, low-temperature workshop and alternating cold and hot working conditions.

The products are manufactured by high-temperature vacuum casting with full-process vacuum defoaming, combined with constant temperature curing, precision straightening and surface fine grinding, completely eliminating defects such as bubbles, trachoma, unevenness and bending deformation. All products are fully inspected before delivery with qualified flatness, straightness and hardness accuracy, meeting the assembly requirements of precision equipment.

Conventional sizes and hardness PU rods are in sufficient stock with fast delivery after order placement. The production cycle for custom sizes and special performance products is 3-7 working days, and urgent processing is available for deep-processed special-shaped parts. Professional packaging is adopted throughout the process to avoid transportation damage. We support sample delivery first, bulk ordering and long-term cooperative drop shipping services.
