Products Description

Foam Filled Tire

This series of polyurethane foam-filled wheel assemblies are specially tailored to serve as rear wheel components for electric wheelchairs. Each wheel adopts a two-layer composite structure, with premium rubber shells as the outer layer and microporous polyurethane elastic material fully filled inside the tire cavity through dedicated forming techniques. The foam material distributes evenly without empty gaps, bringing steady shock absorption during daily travel. To secure stable surface friction and outstanding wear resistance, we cooperate with reputable tire manufacturers for rubber outer casings. Our mainstream rubber suppliers are Cheng Shin and Innova, both famous brands with mature rubber blending technology. The perfect match of branded rubber shells and integrated foam filler greatly optimizes riding stability and extends the overall service life of wheelchair rear wheels.

Poly Foam Filled Tire Feature And Its Application

PU foam filled tyres, often referred to as FF tyres, are built with two core components: a full rubber outer cover and dense microporous polyurethane elastic material packed entirely inside the tyre cavity. This wheel option brings plenty of practical perks - no need for air refills, total resistance to punctures, zero risk of going flat, reliable shock absorption, no routine upkeep and far safer daily use. It fits electric wheelchairs, mobility scooters, baby pushchairs, delivery robots, workshop trolleys and various sports gear. It keeps the classic rubber tyre look buyers prefer, while fixing all the common headaches of standard inflatable tyres: easy punctures, slow air leaks, sudden flats and endless regular maintenance work.

PU filled Rubber Tires Under the Microscope

When viewed under a scanning electron microscope, you can clearly see the distinct open-cell inner structure of PU tires made by Aleader. The foam pores are spread evenly and stay consistent across the whole tire, with most pore sizes measuring between 50 and 100 microns. This well-balanced internal foam layout is what lets our PU tires outperform many alternative wheel products on the market. Our PU tires deliver reliable bounce and stable performance during long-term use, paired with strong abrasion resistance and great protection against punctures. They roll smoothly with low noise, comply with global eco standards, and hold heavy weights steadily. These wheels are widely fitted on rehabilitation mobility gear, personal travel scooters and all kinds of special transport equipment.

Company Introduction

Two-Part Business Layout: R&D Hub & Mass Production Base

We kicked off our polyurethane material manufacturing business back in 2015 in Xiamen, starting out as a dedicated maker of custom PU wheel components for mobility aids. After two years of steady market expansion, we shifted all large-scale production workshops to Longyan in 2017 to expand output capacity and streamline on-site production workflows.

Right now our business runs two separate functional bases with clear division of labor. The Xiamen branch is stationed inside the CAS Haixi Institute Rare Earth Materials Research Center, serving as our core technical lab for joint material research and formula iteration. The Longyan park acts as our centralized mass production factory, housing full molding, filling and assembly production lines. We also run a secondary subsidiary specializing in PU/PIR ventilation duct thermal insulation panels, covering two major industrial tracks: mobility accessory foam parts and HVAC thermal insulation materials.

Co-Development Platform With Research Institutes & Senior Technical

Our in-house technical team boasts more than two decades of practical experience fine-tuning polyurethane formulas and perfecting foam forming techniques. Rather than only conducting independent internal trials, we've established enduring collaborative research links with two authoritative academic research bodies.

We've set up a dedicated joint research lab alongside the Rare Earth Materials Institute of the Chinese Academy of Sciences. Meanwhile, we keep consistent technical communication with Professor Tang from Sichuan University's Polymer Engineering faculty. Our factory engineers and university researchers cooperate closely on material modification trials, performance upgrades and new product development projects. Every exclusive foam formula developed from joint lab testing is put into mass production for our wheel and foam products, helping us create unique performance edges that set us apart from ordinary manufacturers in the market.

Diversified PU Product Portfolio & Matching End Market

We develop five core series of polyurethane finished items to form our complete product portfolio, among which microcellular solid wheel tires account for 70 percent of our overall sales revenue. Our full product scope consists of microporous elastic wheel parts, high-elastic foam semi-finished blanks, one-piece integral skin molded components, flexible PU sponge base materials, and customized lightweight hard foam inserts exclusively built for carbon-fiber wheelchairs.

Our finished goods act as steady supporting parts for famous brands spanning various sectors. Our microcellular solid wheel range has sustained long-term supporting partnerships with producers of electric wheelchairs, mobility scooters and intelligent service robots. Our high-resilience foam stock is a designated raw material supplier for Sealy, an internationally renowned high-end bedding brand. Custom molded integral skin foam components are extensively applied to medical equipment handrails, seat cushions and infant safety seats. The rigid foam filling pieces work as standard auxiliary materials for carbon-fiber wheelchairs, fishing gear and model plane accessories.

Standardized Internal Management & Specialized Client Service Team

The enterprise builds clear hierarchical department framework and complete standardized operation documents that fully comply with ISO9001 quality management certification requirements. Independent departments take charge of R&D design, raw material procurement, on-site production scheduling, quality inspection, finance, warehousing and logistics, with clear job responsibilities for every post.

We split the customer service team from the sales department as an independent functional group, exclusively responsible for pre-order technical consultation, real-time order progress tracking, installation guidance and post-delivery problem feedback handling. Standardized customer communication files are archived completely, enabling rapid response to all types of demand raised by global buyers and institutional partners.
