We made these P traps for HVAC equipment. We considered smoke gray, with butyrate or PETG tubing. In the end, we went with a .5″ OD x .060w, clear transparent butyrate tube. Got to admit, this was a challenge to get this tiny multi-bend right. The plastics...
Provista (PETG)
Our customers often ask us what grades of USFDA or NSF compliant tubing that we extrude for food contact. Generally, for caps, closures, and cups, FDA has not established compliance. Thus, UV stabilized butyrate (our formula 576E) is considered the standard. However,...
Here above we have an example of a larger OD tight-radius-bends. This one is a 4.750 OD tube bent on a 13″ center-line radius. You will notice that the right side of the bend has an extended tangent and the accuracy of the bend is measured by the inside wall...
Besides solvent welding, there are several other methods to couple your Flares and Bells to our tubing. Many of our customers want to easily access sleeves and couplings for cleaning of the pneumatic line. Axial Slit and Hose Clamp: We simply provide four .125″...
Sometimes our customers need to couple dissimilar plastics tubing. Most often they couple provista (PETG) tubing with butyrate (CAB) sleeves. We recommend this technique. It is simply using the molding shrinkage of a heated tube to form a compression coupling. After...
Had a visitor in my office this morning. Poor fella, he had spent the entire weekend in a self imposed terrarium. He was pretty shook up, but we removed him to the great outside and gave some nutty treats and water. After a few hours he went his own way. He ate a bit...
Our Stratus line is used for LED lighting. Recently we received a request for a frosted tube. The link below gives Eastman’s response, but for small extrusion runs we have a Per-Fix solution from Chem Pak. We have other methods, but the Per-Fix 6500 method is...
This week our challenge was to make a simple funnel flare– 3” ID tube to a 4” ID tube. The trick was to do it without tooling. The cup manufacturer company wanted only three flares to put at cup entrance points of its pneumatic transport system. Busada makes all...
Puck Conveying: Busada tubing has been long-known for excellence in pneumatic conveying of cups, containers, caps and such. Our butyrate line enters its 7th decade. We also supply a USFDA NSF 51 approved PETG (Provista) tube (UVO stabilized) and Tritan (tough as...
We have extruded oval tubing for over a decade, but this is the first time we extruded it in our PETG (Provista) formulation. PETG has some advantages over CAB in that it is FDA and NSF compliant with food contact, and our employed formula has passed the NFPA 286...
We received a beautiful panoramic virtual tour of the Roasting Plant’s restaurant in Michigan. The engineering here is a work of art. We provide tubing and bends in a Provista PETG formula that is NSF-compliant and FDA-approved. Click this link for a beautiful...
Recently we received a request for some “giant elbows, about a 15 ft. radius to load material up a silo. This was hard for me to comprehend— for these bends would be not only huge but bent three-dimensionally. When the prints and drawings came in this seemed...
The Roasting Plant has just opened up a beautiful facility in Denver. We work with Advance Design Solutions to do our small part in this. We make the tubing and bends. The Roasting Plant uses cutting-edge technology in their stores, and the result is truly a mix of...
Recently we were given the challenge to produce a tight radius bend to replace a metal fruit chute (peaches). The bend needed a 6″ ID and a tight 12″ radius. We were able to accomplish this by flaring a 5″ ID tube to 6.5″ ID and bending the...
