B2X Opti-form® – Your prefered Blue Material

B2X is the plug assist material to combine the toughness of engineering thermoplastics with the low thermal conductivity of a syntactic foam. Plug assists made from B2X will resist the chips and dings associated with production abuse while reducing mark-off and sticking of difficult to process polymers. B2X maintains the high thermal stability required to process today’s thermoformed polymers. In addition, B2X eliminates the machining difficulties of conventional syntactic foams. This product does not produce dust during machining and finishing of plugs.

For PP, PET Thermoformed parts:

  • Productivity + 5 % to 35 %
  • Reduce Thickness -3 to 15 %

OPTI-FORM B2X may be used in a wide variety of applications on sheet-fed, rotary, orin-line machines. It may also be used with most commonly thermoformed materials, and has proven quite effective with polypropylene and other polyolefins. With PP & PET we will give better productivity than any other epoxy syntactic. OPTI-FORM B2X is ready to replace other thermoplastic syntactic materials such as Hytac® B1X.
