Products Description
2.80/2.50‑4 Dimension & Purpose‑Built C178 Tread Profile
Built on proven 2.80/2.50‑4 industry dimension, this C178 PU foam filled tire is engineered for light‑load mobile hardware that switches frequently between indoor premises and outdoor passages. Its distinctive scattered block‑type tread delivers reliable contact against tiled surfaces, compact gravel and worn asphalt, without bringing excessive rolling resistance during daily travel. Customers may select standard black rubber or non‑marking grey compound; the grey option leaves barely any scuff traces on delicate floor finishes. Every finished unit goes through dimension spot‑checking, enabling simple swap‑in installation without altering existing mounting brackets.
Encapsulated PU Foam Core Eliminates Inflation‑Related Failures
The tyre inner cavity is entirely encapsulated by high‑density polyurethane foam, removing inner tube and air‑chamber structure completely. This filling method gets rid of typical pneumatic‑tyre troubles including sharp‑object piercing, gradual air seepage and sudden functional breakdown on site. Unlike overly‑hard solid rubber wheels with harsh ride feedback, the foam matrix retains moderate yielding capacity to absorb jolts coming from uneven ground. Operators skip regular pressure inspections and supplementary inflation work, supporting long continuous operating cycles with zero air‑related maintenance.
Homogeneous Foam Distribution Delivers Stable Multiterrain Rolling
Thanks to evenly dispersed inner foam substance together with well‑arranged C178 tread blocks, this filled tyre maintains steady travel status across mixed ground conditions. It weakens harsh vibration passed toward equipment frames while rolling over small bumps, pavement cracks and floor seams. The balanced hardness setup reconciles weight‑bearing capability and flexible cushioning effect, avoiding rigid bounce or insufficient friction. Even under prolonged working loads, the tyre keeps its circular outline and follows consistent travel track without swaying or offset drift.
Our Company
The revenue proportion of five core PU product lines is distinct: microcellular solid tires account for 70% of total sales, high-resilience foam blanks and integral skin accessories each take up 10%, PU sponge raw materials and rigid fillers for carbon wheelchairs each make up 5%. Micro solid wheels steadily support leading manufacturers of electric wheelchairs and intelligent robots worldwide long-term; high-resilience foam materials continuously supply global Sealy memory pillow production lines; integral skin parts can be customized for medical armrests and infant safety seats as required; rigid filling components fit competitive fishing tackle and lightweight aircraft model parts.
The complete PU product matrix covers five segmented commercial fields: mobility rehabilitation equipment includes electric wheelchairs, medical nursing beds and adult walkers; civil travel goods cover baby strollers, shared e-bikes and lightweight scooters; intelligent industrial equipment contains service robots, multi-purpose trolleys and small farm machinery; lightweight special parts fit carbon wheelchairs and professional fishing tackle; Xinyonghua's PU/PIR boards serve exclusive matching materials for central air ventilation systems.
Drawing on over two decades of frontline PU molding experience, our dedicated tech R&D team delivers integrated custom PU wheel solutions for global purchasers. We adjust outer sizes, anti-slip treads, raw material hardness and matched rim structures on demand. The stable annual total capacity of PU tires and matching foam accessories reaches 2 million sets, and sufficient manufacturing capacity can undertake differentiated custom production orders for all mobility and transport equipment.
