Perspex vs Polycarbonate screen
« on: June 02, 2020, 05:40:09 pm »
I found a nice bigger screen for my 2010 GS1200 from Wareagle, but its Perspex.

Now the question?

Is a perspex screen a concern? Safety and does it not crack easily?

Perspex cracks on impact, it may shatter even, and this whilst Polycarbonate (sometimes called Lexan) bends.

If polycarbonate has not been uv stabilized, it will start "crazing".... Small hair cracks and yellowing will occur.
Perspex the same, but is much more brittle.

A corrugated iron screen would be more suitable.

I've used Perspex/acrylic for large road bike screens, it is UV stable and easy to work with without using an oven and I don't make a habit of going over road bike handlebars. 3mm Perspex sheet is not going to cause any injury to you, it will break long before causes injury. For an off road screen, especially one you may want to take off and put in your backpack polycarbonate/Lexan is the only way unless you want a bag of plastic bits. Use 4mm sheet and heat it slowly to form it, it will bubble otherwise.

Is that screen in the pic really perspex? Seems quite surprising that they could get away with commercially marketing it.  ???

I made a perspex screen for my KLE , had a minor fall and that perspex shattered into shards that could kill a person.

That is the real problem when Perspex breaks it shatters into very sharp shards.

Those Shatterprufe rulers from when we were kids, they are made from Polycarbonate. They way those rulers break is how Polycarbonate goes. Also a stone will be deflected by a PC screen and will probably come straight through a Perspex screen.

Anti shrapnel shields are made out of lexan?

and some use perspex, the perspex you buy today is no longer the same formulation of WW2 perspex, hence my comment. :sip:
