7Inch Solid Polyurethane Tires

Constructed from microcellular elastic raw material, polyurethane wheels feature reliable elastic recovery capability. The internally distributed tiny pore structure works to absorb vibrations and suppress running noise, bringing smooth and pleasant travelling experience for end users. Thanks to its remarkable noise suppression capability, this wheel delivers far quieter rolling performance compared with many conventional wheel options. It has become a preferred wheel solution for scenarios requiring low operational noise, widely adopted on various mobility and rehabilitation equipment.

Boasting a comprehensive set of desirable characteristics including airless construction, effective shock buffering, low rolling noise, reliable safety performance, eco-friendly composition, zero regular servicing and extended service life, these polyurethane tyres suit a broad array of mobile equipment. Common applicable devices cover manual and electric wheelchairs, elderly mobility vehicles, lightweight bicycles, baby strollers, e-scooters and workshop utility trolleys. They serve as ideal original fittings and aftermarket replacement wheels for rehabilitation, daily travel and light handling equipment.

In our factory,we perform the following tests to ensure that all our products operate at good performance during their long service life:

• Rolling Drum Test
• Resilience Test
• Static Load Deformation Test
• Static Recovery Test
• Static Load Recovery Test
• Side impact
• Runout Check

We build long-term deep technical partnerships with two top-tier academic research institutions: Sichuan University College of Polymer Science and Engineering, and the Institute of Rare Earths under Chinese Academy of Sciences. A formal joint R&D laboratory was jointly established with the Xiamen Rare Earth Research Institute in 2023, dedicated to developing proprietary modified polyurethane formulas and realizing industrial transformation of laboratory polymer research outcomes. Professor Tang Jialing from Sichuan University's polymer faculty joins our technical iteration team to guide raw material formula optimization and product structural upgrading. Our in-house R&D team accumulates over 20 years of frontline polyurethane molding experience, focusing on developing low-density lightweight foam, wet anti-slip wheel formulations and puncture self-sealing tire materials to break through traditional PU product performance limitations. 

The enterprise divides business functions reasonably, separating customer support from the sales team to build an independent customer service section with exclusive service workflows. This team takes charge of full-dimension client services including pre-order technical drawing communication, sample progress tracking, bulk order production scheduling follow-up and post-delivery assembly troubleshooting. We support flexible order modes to fit different buyer demands: small trial batches for new product prototype testing, medium replenishment orders for brand distributors, and large-scale full OEM mass production for complete machine manufacturers. Our annual output reaches around 2 million sets of PU tires and matched foam accessories, with stable delivery capacity to support long-term bulk stocking cooperation of global partners.

Our medium-long term core target: Take part in drafting industrial standards for segmented PU sectors, continuously deepen technical iteration and refined supporting services, expand global trade channels. In the future, we aim to become an integrated full-chain PU service provider, supplying high-performance polymer raw materials and complete integrated solutions worldwide, and jointly build a brand-new industrial ecosystem with domestic and overseas partners.
