- Red PP-on-PP Dual-Color Injection: The wheel uses PP-on-PP dual-color injection molding — a red PP tread layer over a black PP core. This gives a premium two-tone look while keeping the wheel 100% plastic, lightweight, and rust-free.
- Shore 95-98 (D Scale) — Hard & Durable: PP hardness of Shore 95-98 on the D scale means the wheel resists deformation under heavy static loads. It will not go flat like rubber, and it outlasts soft TPR in high-abrasion environments.
- Lightweight — Easier to Push: No iron core means significantly less wheel weight. A lighter wheel means lower rolling resistance and easier pushing, especially for female operators and elderly users.
- Rust-Free — For Humid & Wet Areas: The all-plastic wheel will never rust. Safe for outdoor use, wash-down areas, food processing, and marine/offshore environments where iron-core wheels would corrode.
- Budget-Friendly — Cheap & Practical: PP is the most cost-effective caster wheel material. You get 300kg capacity at a fraction of the cost of PU or nylon. Perfect for price-sensitive projects and large volume orders.
- Non-Marking & Chemical Resistant: PP tread will not leave black marks on epoxy or concrete floors. Resists most acids, alkalis, oils, and cleaning chemicals.
The 6 inch size is the heavyweight of the PP series. Its 300kg capacity and 190mm installation height make it the first choice for heavy industrial equipment on flat factory floors.

- Hard & Wear-Resistant: Shore 95-98, outlasts TPR and rubber
- Non-Marking: Will not blacken epoxy or concrete floors
- Chemical Resistant: Withstands oils, acids, alkalis, and cleaning agents
- Stable Height: No spring means equipment stays at a fixed working height
