Destructive testing
All of our locally-manufactured flooring solutions are extensively tested for durability, elasticity and overall strength to ensure the highest quality. These images show our Aralux™ PMA surface undergoing strenuous destructive testing in Singapore. These tests revealed the unprecedented elasticity of Aralux™ PMA, showing the substance to have a crushing strength of 350kgf/cm2. Most blows and shocks are easily absorbed, and the flooring easily withstands heavy traffic.
Elasticity Test
A sample of Aralux P.M.A. was arranged as an unsupported beam. A load was applied centrally. At the first appearance of cracks the test was concluded.
As will be seen from the diagram, Aralux P.M.A. displays extremely good elasticity, offering a number of practical advantages. Blows and shock are, to a large extent, absorbed by the flooring. Vibrations imparted by wheeled traffic are not fully transmitted to the sub-floor and structure. The flooring withstands the effects of heavy traffic, borne on small diameter wheels.
Further, the flooring may be applied to non stable sub-floors, such as those of timber, sheet steel, asphalt, etc. Also, should normal expansion cracks occur in concrete sub-floors, these cracks will be taken up by the elasticity of the material.

Chemical Resistance
These tests were carried out on fully cured, unfilled cast resin immersed in the various chemicals for three months. The results provided an accurate assessment of change in weight, final appearance and surface damage.
Sample laminates should, however, be tested under operating conditions before embarking on large scale production.

Key:
0 = No Attack : satisfactory.
1 = Decolouration, a slight attack : suitable for limited use only.
2 = Attacked : unsuitable for continuous exposure.
3 = Severely attacked or destroyed : unsatisfactory.
