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,...

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...
Is it a Pipe or a Tube? We get this question all the time, and sadly it usually comes when a customer orders "pipe" when what they really want is "tubing." What is the difference between pipe and tubing? To put it simply, all pipe is tubing, but not all tubing is...
Depending on the wall thickness and tolerance (length and squareness) we can saw cut, core cut (blade), or lathe cut tubing to length. [TABLE] Blade cuts are very square and have a soft feather edge (no sawdust). The feather edge is a result of heat generated from the...
Tritan: Our first extrusion of Tritan tubing was big in itself. It produced the largest Tritan tube in America to that point. The 5" OD x .250w tube was designed for a home-consumer company. Now we extrude Tritan up to 10" in diameter. Tritan is a monster tube. It has...
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...
Offsets: Busada was one of the first plastics tubing and pipe manufactures to offer customers long radius sweeps, and we have done it for over 65 years. Before we had our advanced heaters, we would use hot oil, salt, glycol, vermiculite and other ways to heat the...
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...
When most people think of belled pipe, they envision PVC pipe that often comes standard with a belled end on one side. PVC pipe manufacturers, thus have specific belling machines dedicated for specific pipe sizes and schedules. Busada clear tubing and pipe, however,...
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...
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 ideal...
The nomenclature of bells and flares varies throughout the industry. We follow a simple definition. 1) A flare is a sloping conical expansion of a tube. Flares assist in funneling an object or carrier into the pneumatic tube system. Flares are usually defined by ID,...
This week we had a challenge. A customer ordered a specialty bend with 4 inch ID on a 20” Outside Radius. The bend was to have an extended tangent on one side of 15” and a short tangent of 1.125”. The customer wanted to put the bend directly into a chute for their...
How to identify the radius of a bend for a bend less than 180 Degrees. Imagine if you got a picture like this in your email and your customer said, "make us one just like this." On top of that, they insist that this is a bend on a 24" radius. They can't ship you the...
