G-Form's PORON XRD Extreme Sleeve: Bowling ball meets iPad, tablet lives

By | April 10, 2011, 7:42pm PDT

Summary: How does an iPad survive over 3000Lbs of impact force? With a revolutionary space-age material known as PORON XRD.

Over the last couple of days, I have been closely examining the product development of a new iPad 1/iPad 2 slip case by G-Form, a company that is extremely new to the consumer electronics accessory industry but has a lot of experience in producing knee and elbow pads for high-impact and extreme sports.

Those of you who travel with an iPad 1/iPad 2 or even use it around the house or at your business might want to consider pre-ordering one of these cases at $59.95. I’ve gotten that much confidence in this product already that I can say this is the closest thing you are going to get to making your iPad impact proof under heavy travel and when carrying it around in typical business usage conditions.

I’ve been lucky enough to have been supplied with an early engineering prototype of G-Form’s “Extreme Sleeve” and I have to say that I’m extremely impressed with the product so far and intend on travelling with it and my iPad 2 this week.

What’s so special about this case? It’s made of a soft cushioning material known as PORON XRD, which is a memory foam manufactured by Rogers Corporation that is very similar to the type of material used in the Tempur-Pedic bed. PORON XRD is used in sports protective apparel, such as in the inside of NFL football helmets as well as various types of torso, knee and shin pads as well as for industrial safety footwear.

However what’s different about this foam (which is made of sustainable, recyclable materials) is that instead of being designed to relieve pressure on body parts by conforming to the shape of the subject, it is designed to spread the kinetic energy of the impact of an object.

Because it spreads the energy rather than concentrates it in one area, it amazingly permits a 12lb bowling ball from a three-foot drop to hit an iPad, screen facing up on top of a concrete slab without causing any damage.

That’s roughly equivalent to over 3000 pounds of force directly hitting the iPad.

The enclosed video at the top of the article showing the impact/shock results between an OtterBox and a G-Form Poron XRD case is an eye-opener. The OtterBox, which I consider to be one of the strongest forms of iPad protection on the market, was unable to protect a direct impact on its polycarbonate cover by the dropped bowling ball and resulted in a shattered glass screen.

The G-Form case, however, completely absorbed the impact and the iPad walked away unscathed.

It should be added that the OtterBox is a rigid case which may or may not not be better in absorbing side impacts and preventing dents in the aluminum housing of the iPad than the G-Form case (although the PORON XRD material does protect the sides of the casing as well) so I think as to what case is better for protecting your device depends on the type of torture you intend to put your iPad through.

I’m certainly very interested in seeing what OtterBox issues as a response, as I know they are in the process of designing their Next-Generation Defender Case for the iPad 2.

However, I think that for most people, the much lighter PORON XRD foam used on the G-Form rather than the polycarbonate plastic and rubber armor on the Otterbox Defender will provide superior protection against most direct drops and hits to the screen.

We’ll see this week how this case performs as I bring the prototype on vacation. I’ll be sure to have a full review of the product once I have the full retail version in-hand.

D3O material trounces Poron XRD?

Hard to know if this is objective but:

It would also be good to know what the density of each material is...

BTW, this is not meant as a contradiction, just an FYI. Looks like Otterbox has some "stiff" competition, wink
It would be more likely that the iPad will drop on the edge rather than falling down flat on the screen. Unless you intend to put your iPad in a luggage and let it goes into the cargo, I think side protection is way more important.

The logical question follows:

So who does have the balls big enough to break an iPad in one of these cases?
@Mac Hosehead

The real question is .. which video director has the balls to do more than one video take with the OtterBox product?

I just placed an order for this protective case.

I chose the "Black" colored case because, when traveling by automobile, I have a habit of placing the iPad on the car floor and if I leave it in the car, the black color will help to avoid drawing attention to the iPad inside.

BTW, just one question. How soon does the memory foam used in this protective sleeve revert to full 100 percent protection potential after sustaining a force impact? Another way of asking the same question is after dropping the bowling ball onto the PORON XRD case, another bowling ball was dropped within, oh say ten seconds or so, of the first impact. Would the iPad still be protected to the same degree?
