Specification:
Polypropylene (PP) ROD
Product Info
Polypropylene (PP) Sheet (sheet) and Rod (bar).
Polypropylene is a chemical PP plastic resistance often compared with PVC-U which also has good chemical resistance. The main advantage of PP to PVC-U lies in its ability to survive at application temperatures of up to 100 C, we know PVC-U only lasts up to 60 C. In addition, for certain chemicals, such as acetic acid and chlorobenzene, PVC-U cannot survive, while PP can be used up to 100 C without problems.
To overcome the shortcomings of PVC-U in temperature problems, the alternative that is often used is PVC-C (Chlorinated PVC) which has a continuous use temperature of up to 85 C. Unfortunately the increase in the PVC-C temperature range is highly dependent on the post chlorination process and the purity of raw materials used. If the two factors are not optimal, the temperature resistance of the resulting PVC-C will not reach 85 C so that it does not solve the problem of PVC-U temperature limitations. A better alternative is to use PP that can be used up to a temperature of 100 C.
With PP specific gravity 0, 91 gr / cm3 which is much lower than PVC-C 1, 55 gr / cm3, PP is much lighter so that the price of PP material per kg weighs lower than PVC-C. Light weight combined with good chemical resistance makes PP economically efficient for the chemical industry
