Product Name: Vinyplan 6580/6571, 6764A-60, 6577, 6566, 6766 and 6599
Test Method: Contamination by fluids, chemical exposure with mechanical testing
Client: Scantarp Oy
Test Result:

Visually, the surface structure of the samples was not altered due to exposure, i.e., no cracking, blistering or other damages could be observed, except for one sample, Vinyplan 6766, a fracture was observed after an exposure to kerosene. The tensile and tear properties of products containing only PVC weakened more than the properties of products containing also PU. The best results were obtained for the product with the highest amount of PU in the top coat.

Test Purpose:

To show that the materials withstand contamination by fluids, diesel, kerosene and crude oil. The selected fluids are those for which the material is likely to be exposed to during its life cycle, either occassionally or over extended periods.

Test Method in Detail:

Exposure method: The long-term contamination (8 weeks) by selected fluids: Diesel (commercial), kerosene (JET-A1), crude oil (Sour, min 0,5% of Sulphur). Test cycle: 8h immersing (soaking), 16h drying in air for kerosene and diesel. Continuous immersion for crude oil, applied by brushing. The test method is based on MIL810G 504.1 “Contamination by fluids” Mechanical tests DIN 53363 tear strength test EN ISO 1421 / DIN 53354 tensile strength test
