HOW TOUGH IS SOLID-BOX?

The short answer is ‘very tough’, especially given that it’s a plastic enclosure. SOLID-BOX has an impact rating of IK 08. To pass that test, it had to withstand an impact of five joules – a 1.7 kg mass being dropped on it from a height of 300 mm.

On the IK scale, that’s pretty serious. Let’s put it this way – there are welded stainless steel enclosures that have a similar or lower IK rating. And stainless steel is the go-to option for merciless, unforgiving environments. When it comes to IK ratings, SOLID-BOX can go toe to toe with stainless steel and provide a very serious and less costly alternative.

Why is SOLID-BOX so tough? The design is key, but we’ll come to that. First, let’s talk about the plastic we used. Those of you familiar with recent OKW product launches will know that ABS (Acrylonitrile Butadiene Styrene) – once the plastic of choice for enclosures – has increasingly been superseded by either ASA (Acrylonitrile styrene acrylate/acrylic styrene acrylonitrile) or an ASA+PC-FR blend, both of which offer greater UV stability.

Now new SOLID-BOX employs a different blend – PC+ABS-FR. It contains plenty of polycarbonate (PC), the plastic used in riot shields, CDs and bullet-proof glass. Polycarbonate is 250 times stronger than glass and 30 times stronger than acrylic.

Blending PC with ABS enhances the processability and flame retardancy of the material. It’s UL 94 V-0 in the case of SOLID-BOX, which has an increased heat distortion temperature (Vicat/B 120 = 110°C), and chlorine- and bromine-free flame resistance.
