Company Introduction
Aleader first launched its polyurethane manufacturing line in Xiamen after its founding in 2015, then moved all core production workshops to Longyan Innovation Park in 2023 to build a dual-operation mode separating material research and mass output. The group runs two separate professional subsidiary arms. Our Xiamen branch is stationed within the CAS Haixi Rare Earth Materials Research Institute, acting as an internal material testing lab and external technical exchange hub. The UNT division based in Longyan specializes in PU and PIR heat preservation boards for ventilation pipelines plus supporting installation fittings. Our flagship Longyan manufacturing base solely develops and produces microcellular PU wheels for rehabilitation mobility devices, creating a dual-industry layout spanning mobility spare parts and construction thermal insulation goods.
Our water-foamed microcellular PU raw stock meets international RoHS and REACH environmental standards, emitting zero hazardous volatile compounds in long-term operation to satisfy safety criteria for medical gear and childcare goods. The porous internal framework balances vibration buffering and weight-bearing performance, removing hidden dangers like air leaks and sharp punctures seen on inflatable tyres and cutting routine upkeep work for end users. Our PU wheel series suits diverse sectors: rehab mobility gear, daily transit tools and smart handling hardware. This includes powered wheelchairs, medical transport trolleys, senior scooters, e-scooters, public bikes, pushchairs, service robots, factory trolleys and mini farm equipment. We offer tailored material formulas to adapt to varied road surfaces and load demands of different devices.
Our technical team consistently advances upgrades to proprietary PU material recipes, with four cutting-edge new wheel variants now ready for mass manufacturing. These include high-grip wet-condition tyres, ultra-low weight PU wheels built for carbon fiber mobility gear, lightweight ETPU microcellular wheels via supercritical foaming, and self-repair foam-filled tyres fitted with built-in sealing layers. Moving forward, we intend to broaden the application scope of modified polyurethane polymers and expand our lightweight wheel component lineup. We will also deepen lab collaboration with academic institutions to turn advanced polymer research into marketable finished goods. Our long-term target is to become a globally trusted supplier of tailor-made PU mobility parts, boosting overseas market presence alongside all brand collaborators.
Products Description
Product Intro Overview
This all-rubber-free foam integrated wheel abandons air-filled inner chambers entirely, crafted with proprietary modified polyether polyurethane raw stock through one-step microcell foaming molding. The compact compacted foam matrix eliminates the common road hazard of tyre blowouts caused by sharp foreign objects. Tuned elastic rigidity balances load capacity and road shock absorption, suitable for daily outdoor and indoor low-speed transport vehicles. Every finished wheel undergoes full mechanical performance testing before delivery, freeing equipment operators from frequent patching, air refilling and pressure inspection cycles throughout the whole service life.
Diversified Matching Equipment Scenarios
This damage-resistant PU wheel fits various light transport and rehabilitation machinery, usable as original factory matching parts and aftermarket replacement spares:
- Rehabilitation mobility apparatus: Manual & power wheelchairs, walking aids, hospital patient transfer trolleys
- Daily travel tools: Elderly electric mobility scooters, multi-seat folding baby strollers, light auxiliary electric carts
- Intelligent handling equipment: Drive and swivel wheels of delivery robots, warehouse transport trolleys
- Light industrial gear: Portable fishing gear carriers, miniature gardening carts, small model aircraft brackets
Unique Anti-Puncture Structural Design Logic
Unlike thin sidewall inflatable tyres that easily crack after piercing, this wheel adopts multi-layer gradient density foaming layout. The outermost contact layer adds high cut-resistant additives to block nails, broken glass and metal fragments from deep penetration. The dense microcell mesh inside features strong automatic rebound recovery; minor surface scratches will quickly shrink closed without forming persistent leak points. Since there is no air storage cavity inside the tyre, surface scratches will never trigger sudden loss of supporting force during travel.
Stable year-round material performance Specially adjusted PU formulation avoids brittle cracking in cold weather and soft deformation under long-term sunlight exposure, maintaining consistent elasticity in tropical and temperate regions.
Low-resonance quiet rolling Uniform fine pores weaken friction vibration between tyre and ground, greatly reducing running noise for devices requiring silent operation.
Low-consumption abrasion resistance Dense outer wearing layer slows tread thinning under frequent back-and-forth running, extending usable cycles far longer than ordinary lightweight foam wheels.
Eco-safe raw material composition Zero ozone-depleting substances and heavy metal additives, fully compliant with global RoHS and REACH environmental testing standards.
