We are often approached for heavy-walled tubing in CAB (butyrate), PETG, and Tritan up to 1/2″ in thickness: no problem. We have extruded a 3″ OD Butyrate tube with a .625″ a specialty product for. S. King Fulton Corp. They chose Busada butyrate tubing for its toughness and UV stabilization. It could absorb the impact of docking marina craft, and enhance the appearance of marinas by its optical clarity. We extruded this tube for over a decade through both air-cooling and vacuum sizing processes.
Butyrate was selected for this application because of its excellent UV stabilization, weatherability, and clarity.
Here we see these heavy tubes lining a Florida marina. Yes, it is a bit dated. Love the bouffant!
