Hybrid Foam‑Core Construction Balances Cushioning And Puncture Proof Performance
Combining rubber outer casing and high‑density injected PU foam core, this tyre inherits the soft ride quality of pneumatic tyres yet removes flat‑out risk. Without inner‑tube structure, it will not fail abruptly when running over sharp scraps. Even if the rubber shell sustains shallow cuts, the interior foam still retains full supporting force. Operators skip routine inflation checks, avoiding the recurring maintenance work required for ordinary air tyres under frequent use.
Tough Rubber Compound Against Abrasion And Sidewall Cyclic Deformation
Chengshin original rubber compound strikes a good balance between wear resistance and pliability. Thickened tread layer slows material loss under long‑hour rolling. Reinforced sidewall withstands repeated squeezing and distortion under variable load. It greatly lowers common failures like surface chipping, premature cracking caused by frequent flexing. Stable physical properties hold up for long‑term household usage as well as light‑duty commercial cycles.
Our Company
Full-group Industrial Layout & Two Independent Business Branches
Founded in Xiamen in 2015, the brand launched research into new polyurethane materials and later built self-owned standard industrial parks in Longyan, forming two core bases for technical research and mass production. The group operates two separate business units with differentiated positioning. Its Xiamen R&D branch settles at the Haixi Rare Earth Institute of CAS, a national research platform, to cooperate with top material specialists and build long-term industry-university-research channels. Two production segments run in Longyan: the core line mass-produces full PU fittings for mobility aids, while Xinyonghua division develops PU/PIR thermal insulation panels for central air ducts, supplying auxiliary materials and on-site installation guidance to accept custom orders for two industries at once.
Brand Core Tenet & Unified Staff Code of Conduct
The fundamental founding purpose of the enterprise is to create safer, more convenient and comfortable daily mobility accessories for global end users relying on new polyurethane material technology, with the medium-long term goal of becoming a benchmark service provider for global PU material application. Three core operation rules run through the whole industrial chain: review and adjust business plans with market feedback after implementation, sustain technical breakthroughs to guarantee long-term stable operation, build clear promotion paths for staff and actively undertake social responsibilities. All employees work pragmatically and collaboratively, adhering to quality priority, innovation and win-win cooperation to steadily expand global partnership networks.
Microcellular Pore Structure & Comprehensive Product Advantages
All micro tires adopt eco-friendly water-blown production craft, all finished goods pass dual RoHS & REACH environmental tests, infant foam accessories hold European GS certificates, and bicycle PU wheels obtain official TUV credentials. Under electron microscope observation, cell sizes stably range from 50 to 100 microns with even open-cell distribution, delivering balanced outstanding performance in shock absorption, load capacity and impact resistance. The integrated solid molding structure eliminates regular inflation maintenance, boasts excellent wear and aging resistance, adapts to all complex indoor and outdoor roads, and greatly cuts later operation costs.
