Butyrate, being a cellulosic, is friendly to most fabrications. The days are past when one could purchase butyrate fittings such as elbows and tees, nevertheless, butyrate pipe can be connected to metal or PVC pipe by means of compression fittings, slip fit and O-ring...
Butyrate (CAB)
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 tubing will...
We frequently are asked to make UBends (180°) bends. In a UBend, the offset is twice the radius, and keeping the offset is the trick. In thermoplastics bends the tubing tends to pull in or out (memory) and work as a thermometer with radiant heat. Our process minimizes...
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,...
Busada transparent sleeves can be coupled in many ways: solvent bonding, solvent spot welding, axial slit and clamping, radial slit and clamping, and heat expansion. In situations where attractiveness surpasses utility, we recommend small conical set screws. They are...
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...
Rectangular transparent tubing formed in an extrusion vacuum system has some inherent problems in clarity. For one, the vacuum sizer heads need extra length to combat the vacuum's tendency to round the tube. This tends to introduce draglines and chatter marks. We have...
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...
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...
It happens a lot; don't feel bad. You may not know the exact angle, nor the radius of the bend; you just know that you need the exact replacement fast. This blog will explore several ways to identify your bend, but we start out with the most painless way devised by...
We now have an option for a hard-baked static dissipative coating for our transparent tubing. Most plastics do not give up their electrons easily; they are insulators. And since they are insulators, they are poor conductors of electricity. Thus, electrical charges can...
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...
