Independent Verification
Our products have also been subjected to two rigorous independent tests, the conclusions of which we are pleased to publish below.
EVALUATION OF WEATHERING IN MIXED POLYETHYLENE AND POLYPROPYLENE PRODUCTS
WRAP PROJECT CODE: PLA0007-008
PRODUCED BY: University of Brighton and RAPRA Technology
This study, commissioned by WRAP, provides a technical evaluation of how mixed waste plastics, including the Centriforce products shown in this website, are affected by weather and other aspects of their habitat. The main findings show that as far as the two primary criteria are concerned – mechanical strength and UV degradation – there has been no appreciable deterioration of the materials after continuous exposure of 5 or more years in the field.
The tensile strength of Centriforce materials was found not only to be unaffected by UV exposure, but the study concluded that it might have slightly increased. The bulk solid properties and melt flow characteristics also remain unaffected by UV exposure.
The study showed that the results of the Centriforce products that had been in use for several years were almost identical to the materials we had just produced.
MATERIALS TESTING SERVICES –
UNIVERSITY OF PORTSMOUTH
Full Testing Programme commissioned in May 2004. Summary of key issues:
TENSILE/BENDING TESTS – BS 373
Researchers comment “Because of the nature of the material, will deflect under excessive loading, but not break”.
SLIP RESISTANCE – BS 7976-2 : 2002
Unique extra rough surface rated at Excellent in dry conditions and Fully Satisfactory in wet conditions.
IMPACT RESISTANCE - BRE SCREED TEST
Product showed “no visual signs of distress” and performed significantly better than concrete.
