PU Extrusions

PU extrusions focus on high-strength sealing, wear resistance, and chemical resistance needs. (not suitable for thermal insulation or filling scenarios)

Still troubled by quick wear and seal failure of ordinary rubber parts? PU extrusions break through these pain points with a 100% dense elastic structure. Their wear resistance is 5-7 times that of ordinary rubber, they are oil and hydrolysis resistant, and won’t collapse under long-term stress. They are suitable for high-demand scenarios in industries such as industrial equipment, automotive, and precision instruments.​

Applications of PU Extrusions

We offer targeted solutions for 6 industries, including hydraulic rod dust covers for industrial equipment, brake line bushings for automobiles, conveyor scraper blades for food processing, and cable protection tubes for electronic. There is always an option suitable for your application. We provide free selection consultation, 10-days regular prototyping, 7 days bulk delivery, and a 30-day after-sales return/exchange guarantee.​

Advantages of PU Extrusions

Shore hardness options from 70A to 95A, with a wear rate ≤ 0.02g per 1000 cycles in high-frequency friction scenarios, capable of withstanding harsh conditions like ore conveying and gearbox sealing.

Temperature resistance range of -40℃ to 880℃ (short-term up to 120℃), no brittleness in winter or softening in summer, suitable for cold northern climates or high-temperature engine compartments.

Ester-based variants resist oil and solvents, while ether-based variants resist hydrolysis and seawater. They comply with food-grade standards (FDA certification) and electronic-grade environmental requirements (RoHS), making them safe for use in medical, food, and marine equipment.​

Dimensional Accuracy Guaranteed

Cross-sectional tolerance of ±0.1mm; lip seals, corrugated tubes, and special-shaped profiles can be customized based on 2D/3D drawings.

Continuous supply up to 100 meters per roll, or cut-to-length with a minimum segment of 0.5 meters, ensuring seamless adaptation for the assembly of precision instruments and electronic sensors.​

More importantly, their non-porous structure prevents dirt buildup, requiring only a simple wipe for cleaning. The permanent deformation rate under long-term compression is ≤ 5%, and replacing traditional rubber parts can reduce replacement frequency by 30%, lowering equipment downtime costs.​
