Dymatrix Process Solutions

Asahi/America’s Dymatrix specialty valves and control products were designed in close consultation with semiconductor industry leaders. Significant attention was paid to reducing the stress that can occur from valves in a Chemical Mechanical Planarization (CMP) slurry system.

The evolution of the Dymatrix products has expanded the application horizon. The inherent characteristics of quality craftsmanship, reliable components, flexible design options, and innovation are common to many industries. In addition to CMP processes, ultra-pure water and chemical applications benefit from the pioneering process solutions of Dymatrix Products.

Asahi PolyPure

The PolyPure Natural Polypropylene system provides a cost-effective alternative for a system up to 4″ (110mm). PolyPure pipe is clean room produced. Fittings and valves are also produced in a class 100 clean room, then hot DI rinsed and individually packaged. PolyPure is available in both butt and socket fusion.


  • Pipe and fittings use a virgin, natural random copolymer polypropylene resin (PPr) for the pipe, fittings and valves
  • PolyPure pipe conforms to the requirements of ASTM D-2837-85 for establishing a hydrostatic design basis; the pipe has a standard dimensional ratio of SDR 11 and is pressure-rated to 150 psi at 73.4°F for all diameter sizes 1/2-4″
  • PolyPure systems are specified and installed in a variety of high-purity applications including USP purified water, institutional laboratory and deionized water systems
  • Joining methods: butt fusion, IR (infrared) butt fusion, socket fusion and beadless butt fusion
