Use polypropylene to make their interlocking floor tiles for sports flooring & industrial flooring . For some applications it is the most suitable material.
Neither PVC nor polypropylene are naturally flame retardant but it is much easier and cheaper to incorporate a flame retardant additive in to PVC.
PP tiles does not support combustion and achieves Class 1 spread of flame when tested to BS 476: Part 7 / European Classification: BFL. In other words, it will not support a flame and does not give off toxic fumes if it’s in a fire. It can be prohibitive expensive to get polypropylene to the same standard so if this is important to you, make sure you check with the manufacturer and ask to see their test certificate. Here you can find our fire test certificate.
You may have noticed that PVC tiles tend to be solid where polypropylene tiles usually have a grid structure. This is due to the nature of each material dictating the way it can be moulded. PVC needs fewer flow lines to achieve dimensional stability and prefers a solid structure. As a result it is able to support heavier loads and offers better impact resistance. Polypropylene can be brittle and snap under stress. You will want to consider this if you will be using forklifts or heavily loaded pallet trucks on the tiles.
There’s a common misconception that because polypropylene tiles often have drainage holes in them they offer a higher level of anti-slip protection. Actually the holes are usually there because it’s easier to manufacture polyprop tiles that way or because it’s cheaper. All of our tiles achieve an R10 slip rating.
