Blueline FRPP Floor Drains are used in chemical waste drainage applications such as laboratories in schools, universities, and research facilities. They're molded from proxylene blueline resin, a flame retardant thermoplastic material with excellent resistance to most common and organic mineral acids and their salts, strong and weak alkalis, and most organic chemicals. Joining is done with the Socket Fusion method which provides strong, durable, and permanently sealed joints in chemical waste drainage systems. This heat fusion method uses a thermostatically controlled heat tool for quickly creating tamper-proof joints for above and below-ground applications.
