A lightweight UV stabilized Thermoplastic material developed by Atlas. Soft white in color with good chalk resistance, this tubing machines easily and works well with most glues. Epoxy is recommended for installation. XTC hits slightly softer than the Melamine materials. Not recommended for use in Jump/Break Cues, or for use with any coolants or solvents containing hydrocarbons when machining as the material may break down. Use of Synthetic Coolants or Solvents is fine.
