Cast polyurethane elastomer raw material for roller-skate, inline-skate and scooter wheels. PU is the material of choice for skate wheels — high rebound for speed and energy return, outstanding abrasion resistance for long wear, and great grip and control. Durometer (Shore A 78–90), colour, clarity and rebound are all tuned to your wheel via prepolymer + chain-extender formulation; hot-cast TDI systems give the highest rebound.

Key Features
High rebound & speed Excellent energy return for fast, smooth rolling — key for performance skate wheels.
Outstanding abrasion resistance Long wear life on rough surfaces, far outlasting rubber or PVC wheels.
Grip & control Tunable durometer (Shore A 78–90) balances grip, slide and roll speed.
Clear or any colour Cast transparent, translucent, pigmented or swirl effects for attractive wheels.
Bonds to the hub Casts firmly onto plastic / aluminium wheel cores for a reliable, durable bond.
Custom formulation Hardness, rebound, colour and clarity tuned to your wheels. Hot-cast & cold-cast. OEM/ODM.
The same PU system is used for scooter wheels, skateboard / longboard wheels and other recreational wheel applications.

How Skate Wheels Are Made
1
Set the hub Place the plastic / aluminium wheel core (hub) into the wheel mould.
2
Mix & colour Meter and mix the PU system with pigment or leave clear for translucent wheels.
3
Cast & cure Pour around the hub; the PU bonds to the core and cures to the target durometer.
4
Demould & finish Demould the wheel; fit bearings for a fast, durable, great-looking skate wheel.
Packaging, Storage & Handling
Packaging Prepolymer and curative supplied in iron drums; palletised for export. Bulk on request.

Frequently Asked Questions
What durometer for skate wheels?Typically Shore A 78–90: softer (78–82A) for grip and outdoor surfaces, harder (88–90A) for speed and indoor rinks. We tune to your discipline.
Can you make transparent or coloured wheels?Yes — clear, translucent, solid colours and swirl effects are all possible by pigmenting the PU system.
Hot-cast or cold-cast for skate wheels?Hot-cast TDI systems give the highest rebound and abrasion resistance for performance wheels; cold-cast MDI is easier for general recreational wheels.
Can the formulation be customized?Yes. Rebound, durometer, colour and clarity are all customizable. OEM/ODM supported — request a TDS, MSDS and sample; we reply within 24 hours.
