What is the mimumum bend radius for 6 mm Medite Tricoya Extreme MDF?

What is the minimum radius that 6 mm Medite Tricoya Extreme MDF (an MDF for outdoor use) can be bent to? If possible I want to bend it to a radius of 2500 mm, without kerfing.

It will be fixed with screws over the whole surface, so it doesn’t matter if it wants to spring back. What I’m interested in is if it is likely to crack when I bend it.

I will use painted Medite Tricoya Extreme as the surface layer of a skateboard ramp. The manufacturer doesn’t publish bendability data, and I haven’t got hold of them to ask. The material is very expensive, so it would be great to hear if anyone has experience with this.
