PPro-Seal Natural (PP)

PPro-Seal™ Natural PP has excellent resistance to attack by  most organic and inorganic chemicals in common use. In general,  PPro-Seal™ is attacked only by strong oxidizing acids and is  weakened by certain organic solvents and chlorinated hydrocarbons.  Like all thermoplastic products, PPro-Seal™ will not rust, pit,  scale or corrode. PPro-Seal™ is not subject to electrolysis,  providing years of maintenance-free, leak-free service.

PPro-Seal™ Natural PP is a highly pure product ideal for use in piping systems where purity is not only required, but is essential.  It is often used in the pure distribution of DI water and critical biological fluids where chemical sanitization is needed.

Natural Polypropylene’s (PPn) chemical and physical properties make  it ideal for laboratory and industrial piping where mixtures of acids,  bases, and solvents are involved.
