Polypropylene (PP) sheets
Polypropylene (PP) Sheet (sheet) and Rod (bar).
Polypropylene is PP plastic resistance is often compared with PVC-U which also has good chemical resistance. The main advantage of PP to PVC-U lies in its ability to withstand application temperature up to 100 ° C, we know that PVC-U only lasts up to 60 ° C. In addition, for certain chemicals, such as acetic acid and chlorobenzene, PVC-U can not survive , while PP can be used up to 100 ° C without problems.
To overcome the deficiency of PVC-U in temperature issues, the most commonly used alternative is PVC-C (Chlorinated PVC) which has continuous use temperature up to 85 ° C. Unfortunately the increase in PVC-C temperature range is highly dependent on the post chlorination process and the purity of raw materials used. If these two factors are not optimal, the temperature resistance of PVC-C produced will not reach 85 ° C so it does not solve the problem of PVC-U temperature limitations. A better alternative is to use PP that can be used up to 100 ° C.
With a PP-0, 91 g / cm3 wider which is much lower than PVC-C 1, 55 gr / cm3, PP is much lighter, making the price of PP material per kg weighs lower than PVC-C. The lightweight weight combined with good chemical resistance properties makes PP an economically efficient price for the chemical industry.
Applications: Chemical tanks, chemical pumps, valves, gaskets, pickling tanks, anodize tanks, metal passivation tanks, degreasing tanks, electroplating tanks, etching tanks, galvanizing tanks, spacer for plating, plating barrels, fume exhaust scrubbers and components, tanks and chamber for parts of washer systems, storage tanks and circulation for corrosive solutions, coating tanks, supporting stands for industrial coatings, acid chemical process tanks, dosing tanks, and other applications requiring corrosion resistance.
