Products Description
Polyurethane Foam Filled Tyres
Polyurethane foam filled tyres, also widely known as FF tyres or flat free tyres, are a popular type of non-pneumatic wheel solution specially engineered to replace traditional air-filled rubber tyres. The production process starts with standard rubber outer casings, into which liquid microcellular polyurethane elastomer is fully injected and then solidified to form an integrated foam core inside. This unique composite structure completely removes the need for air inflation, creating a sturdy and elastic wheel that combines the excellent wear resistance and grip of rubber with the outstanding shock absorption and load-bearing performance of PU foam. Different from ordinary solid rubber tyres, this filled design retains a certain degree of softness and flexibility, so it will not feel overly stiff during use. Thanks to mature production technology and strict material selection, these tyres have become a reliable choice for various equipment that pursues stable performance and low maintenance needs across diverse industries.
Structure & Working Principle
This kind of tyre adopts a dual-layer structure consisting of a rubber outer tube and a polyurethane foam inner core, and each part plays an irreplaceable role in actual operation. The outer rubber layer adopts high-quality rubber formula, which is resistant to abrasion, tear and ageing, and can firmly grip the ground on different road surfaces to ensure stable running. The internal foam core features a uniform open-cell structure with cell diameters mainly ranging from 50 to 100 micrometers. The dense and evenly distributed foam holes enable the tyre to effectively disperse pressure when bearing loads, and absorb vibration and impact generated by uneven roads. Since there is no air chamber inside, the tyre will never leak air or go flat even when pierced by sharp objects like nails, glass fragments and gravel. The two parts are closely combined without separation or loosening during long-term operation, maintaining consistent elasticity and supporting performance all the time.
Core Advantages
Polyurethane foam filled tyres possess multiple prominent advantages that make them stand out among various wheel products. First of all, they are fully puncture-proof and flat-free, completely solving the common troubles of air leakage and tyre blowout of traditional pneumatic tyres, and ensuring continuous operation even in complex environments full of sundries. Secondly, they deliver excellent shock absorption and riding comfort, far better than fully solid rubber tyres, bringing a smooth experience for users. In terms of durability, the selected PU materials have good anti-ultraviolet and anti-ageing properties, so the service life is two to three times longer than ordinary inflatable tyres. In addition, the whole product is nearly maintenance-free, requiring no regular inflation, tyre repair or air pressure inspection, which greatly cuts daily maintenance time and costs. All products comply with RoHS and REACH environmental standards, featuring high safety and wide adaptability.
Application Scope
Thanks to its reliable performance and strong adaptability, polyurethane foam filled tyres are applied to a wide range of equipment and scenarios. In the medical and rehabilitation industry, they are the ideal matching parts for electric wheelchairs and manual mobility scooters, as their safety and maintenance-free features can bring great convenience to users with limited mobility. In daily life, they are also widely installed on baby strollers and various hand-push tool carts. In the industrial field, these tyres work well for warehouse handling trolleys, logistics transport vehicles and intelligent service robots, adapting to frequent start and stop and heavy load conditions. Besides, they are also popular for sports equipment and special mobile devices. Whether it is indoor flat ground or outdoor rough roads, these tyres can maintain stable performance, so they are favoured by buyers from different countries and regions around the world.
