1. Solvent-welding butyrate tubing requires, well, a solvent (acetone alone will do it), some butyrate resin, a jar, and a brush. 2. We can provide you with some "fines," or you could cut some of the tubing scraps and generate some clean butyrate sawdust. 3. I like to...
Butyrate (CAB)
Is butyrate an antistat? We get this question often, and the answer is 'at times' and 'no.' Every winter we receive calls asking for help with static buildup in pneumatic systems. Lower humidity brings an increase in static electricity. In pneumatic systems, you can...
Angel hairs and tube abrasions are the nemeses of cap and closure conveyance. On Apr 1, 2009 Shrikant Dhodapkar (and others) published "Understanding Bends in Pneumatic Conveying Systems" in Solids Processing. The document is widely available online. The article has...
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...
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...
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...
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 Mfg. Corp has been manufacturing and selling clear transparent tubing for over 70 years. Only in the last 5 years have we added colors, and so it's been more colors every year. It's about time we wrote a blog on some ways that we can color our tubing. First, we...
One simple way to connect your butyrate sleeves is using four to six cone set screws. Simply mark the spot from 1.5 to 2" from the end of the sleeve. Drill, tap, and lightly torque. The set screws will bite into the tubing. They can be removed for cleaning and...
Fiber-reinforced concrete has been rapidly growing throughout the building industry. Polypropylene fiber can increase toughness and durability of residential concrete. These synthetic fibers need to be uniformly distributed within the mix. But macro-synthetic fibers...
Today we had a request for an expanded sight glass/coupler. This is an easy blog to write because we don't have any idea what this is being used for. Yet, it made a nice picture and it's just one more for the record. We made this by a special process we developed to...
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" axial...
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...
Dealing with Angel Hairs Angel hairs in pneumatic conveyance is a longstanding problem. It certainly is not welcome in transparent tubing. Angle hairs are described by Theile as "those fuzzy, fitful, filmy pieces of plastic that drive us crazy, and. there is nothing...
