High Quality PU Rod Material for Industrial Use

PU rod is a cylindrical or rectangular cross-section polymer elastomer material made mainly from polyurethane through specific processes. Polyurethane is synthesized by reacting isocyanates with polyols. By adjusting the formula, rods with different hardness (Shore A 10~D 80), color (natural, tea, black, etc.), and properties can be obtained. The standard diameter range is usually 18-350mm, and the length can be customized.

Product characteristics

Mechanical properties

High elasticity and wear resistance: The wear resistance is 3-5 times that of natural rubber (ASTM D1044 test), suitable for high friction environments.

Tear strength: The tear strength can reach 30-60 kN/m (ASTM D624 standard), which is superior to most rubber materials.

Bearing capacity: Low compression permanent deformation rate (<10%, ISO 1856 test), suitable for dynamic load scenarios.

Environmental adaptability

Temperature resistance range: -40 ℃~+120 ℃ (special formula can withstand -60 ℃~+150 ℃).

Chemical resistance: resistant to oil (ASTM D471), weak acids and bases, but not resistant to strong acids, strong bases, and polar solvents.

Aging resistance: it can be used outdoors after adding anti UV agent (QUV aging test ≥ 1000 hours).

Functionality

Damping and shock absorption: High dynamic energy absorption efficiency, with a loss factor (tan δ) of 0.1~0.3.

Silent performance: Friction coefficient of 0.2~0.6 (dry state), reducing operating noise.

Electrical insulation: Volume resistivity ≥ 10 ΩΩ· cm (IEC 60093 standard).
