When Bayer came to us with a rush project for a children's learning display we faced a daunting challenge. We needed to take clear, transparent CAB 4" OD tubing and bend it into complex 3D shapes. This was necessary to conserve space and allow the display to break...
Butyrate (CAB)
Plastic Fabrication Company Uses Clear Plastic Sheet for Custom Acrylic Fabrication Occasionally our customers need fabricated sheets for their product. Dominion Energy recentlyneeded a new wet calibration rig to replace a dirty old yellowing acrylic rig. The project...
Building a Flow Loop with Clear Rigid Plastic Tubing and NPT Threads We were recently contacted by a Ph.D. student working on a multi-phase flow problem. The application called for a clear rigid tubing flow loop that would maintain a circular shape under pressure with...
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...
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...
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...
Frequently we 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...
