Butyrate (CAB)

Fabrication by Mitering of Ells, Bells, and Flanges

Here is an illustration showing our method of fabricating 90° ells from a straight section of CAB Tenite clear extruded butyrate pipe. This example is from 4" Sch 40 pipe. The ends of the two pieces to be joined are cut on a 22½° angle. A short filler cut with the...

FDA Butyrate

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...

Funnel Flares Sleeves And Couplings

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...

Colors And Hula Hoops

While we're known for clear, transparent plastics tubing, we do more. Busada has extruded PVC, black ABS, and colored CAB. Last month we set out to run a rainbow of colors from black, red, greens, blues, yellows, and colors in between for a musical piping project....

Busada PETG Tubing For Puck Conveying

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...

Busada Pneumatic Conveyor Tubing Has Done The Job For 70 Years

Going through our file cabinets last week, we came upon this vintage gem. The candy-stripe uniform dates the photograph between the mid-50’s to early 60’s; but the tubing is not dated. Today, cup manufacturers essentially use the same method of pneumatic conveying...

Butyrate Sleeve Checking

An electrical manufacturer had a need for a small quantity of clear, transparent tubing sleeves for its line of ¼” wide blade-type quick connects. We provided them with long sleeves of 2.765" ID in 16" lengths) in Cellulose Acetate Butyrate (CAB). But this particular...

Butyrate Tubing And Hydroponics

Busada CAB (butyrate) tubing was used in hydroponic research at Penn State University and the University of Georgia horticulture departments. Here the tubing was colored on the inside (blue to reflect 430-525nm) to limit growth of algae. A simple aquarium pump...

Butyrate Tubing Clarity And Toughness

Butyrate tubing (CAB) is known for its toughness, but when properly extruded it can compete even with cast acrylic in clarity. At Busada, we cater to the small order; we run in small lots and low screw speeds. Quality matters here, not throughput. We recently sent a...

Sectioned Circular Bend

Whenever I hear of a "circle within a circle" I think of the bizarre description of deity in Ezekiel Chapter 1 (well, in his case it's a wheel within a wheel). In our case, it's a prototype. And it was a challenge. We were to produce an air-tight, water-tight...

Cleaning Transparent Tubing

Cleaning Butyrate tubing: Cellulose Acetate Butyrate, as any transparent tubing can accumulate grime, oils, and get scratched by abrasives. Also, it will weather and age due to UV light and oxidizers. When the latter occurs, the tubing cannot be cleaned by traditional...

Clear, Rigid Transparent Butyrate Pipe VS. Clear PVC Pipe

Busada extrudes Butyrate (CAB), and Tritan pipe in nominal sizes from ½” to 8” and in Sch 10, 40, and 80. We extrude other schedules to order. The picture below is from a recent run of Butyrate 6” Schedule 80 Pipe. Our customer’s engineer was not happy with the...

Coefficient of Static Friction in Butyrate Tubing

We were asked to provide a Coefficient of Static Friction for our butyrate tubing. The problem is that the surface roughness is only one part of the equation, the base material is another. We defined our materials as aluminum and steel with CAB.The simple test for...
