Default RIP—Electric Urethane.

Just heard Tim Dawe has decided to call it a day.
Can't say i blame him given how his ideas keep popping up in other peoples wheels...

Sucks, Skateboarding may have lost a true innovator.

History?
Website link?
Pictures?

I've never heard of them - sounds like a teeny tiny company, I'm probably not alone... but you've piqued our curiousity with a name that's likely impossible to Google or otherwise search...

On a potshot- this worked:

Electric Urethane Manufacturing

But still, how does this affect our wheel market? No more orangetangs? No more Alligators? No more seismics? Any insight?

That's beat! I remember the "Cockroach" wheels and accessories back in the 80's when I was a grom.

Good luck Tim, whatever your next endeavor may be...

The Coretech wheels were supposed to be absolutely amazing.

My 68mm cortech are fast as.

Tim was the first person to use gravity cast cores, this causes the tyre and hub to molecularly fuse together creating one cohesive unit. (usually the formulas and methods are too different for this to occur)
Even his slalom wheels have no mechanical lock between the hub and tyre, and don't need them.

I've also had people I consider reliable say he developed a traction wheel for 3dm, who afterwards had the exact same wheel profile poured by a cheaper manufacturer...

What�s the difference?
Almost three decades ago, the first urethane wheel specifically designed and manufactured for skateboarding made a smashing debut. Since Cadillac introduced this urethane donut in 1973, wheel manufacturers have experimented and tweaked urethane blends to create the perfect roll. The most recent developments in manufacturing technology have produced dual-durometer and cored wheels resulting in faster, smoother, and longer-lasting urethane formulas.

Tim Dawe, owner and founder of Electric Urethane Manufacturing, an Australian-based wheel maker, has been developing urethane technologies since 1981. Recognizing a need for a high-performance skateboard wheel, Dawe set up his country�s first urethane plant. The first sets of wheels coming off his assembly line were hand-poured using a high-speed, high-rebound, and high-abrasion-resistant formula. Electric Urethane has since been refining this formula and further building upon its first-generation wheel.

Currently Electric Urethane produces wheels for three brands: Point Blank, Electro, and Cortech. Back in 1992, Cortech began experimenting with composite, or dual-durometer, wheels. The concept for the Cortech System was developed through a need to create a superior urethane blend that is flat-spot resistant, continues to last, and rolls faster. In order to optimize these specific qualities, a gravity-poured urethane core was combined with Electric Urethane�s abrasion-resistant wheel formula, resulting in Cortech's first dual-durometer wheel.

that's too bad,
businesswise, they were probably at a disadvange being in Australia...

can urethane be reverse engineered ?

how many wheel manufacturers are out there ?

creative urethane
aend
powell ?
??

china ?

Many plastic companies can cast urethane. The actual polyurethane mixtures come from the big chemical companies.

Pretty sure most wheels co's use mixtures of commercial components.
There are things you can add that cause extra molecular bonds and even fillers (mica, UHMWPE) that make for cheap/different wheels.

Urethane can be reverse-engineered, to a certain degree. (got a stim anyone?)
There are companies that specialize in it. But from what I've gathered it's not a guarantee of the same result.

Kind of like how you can know the recipe but still burn the cake...

but can any urethane company just simply copy a big zig/aend urethane...?

I heard taiwan/china have a hard time reproducing quality urethane even though they have the equipment....

Wow. Too bad. This will make me cherish my one set of 68mm coretechs even more. They're always my ace in the hole for slalom racing.

Once again, Aend doesn't make polyurethane. It comes in cans from the chemical supplier. They mix it and cast it.

Here is a video tour of AEND Industries wheel factory:
