Polycrete polymer concrete pipe
Available from Thompson Pipe Group
Polycrete polymer concrete pipe is a composite material consisting of polyester resin, quartz sand, silicate aggregate and quartz filler. As portland cement performs poorly in an acidic environment, it is not used as a binding agent. Polycrete polymer concrete pipe uses a polyester resin to bond the kiln-dried silicate aggregate, thereby creating dense, corrosion-resistant matrix. For special industrial applications where added chemical resistance may be required, Polycrete can be produced using a vinyl ester resin.
Polymer concrete pipe is produced using a vertical casting process, very similar to concrete pipe. Exact amounts of the materials are pre-mixed, with the raw material quantities, mixing sequence and material feeds controlled by a computer. Then, the mixed material is loaded into vertical molds where vibratory compaction is used to ensure a dense, void-free composite structure.
