Measuring Transparency, Lensing, And Optical Clarity

2) Transparency So how do scientists measure clear plastic? The boundaries between ‘transparent’ or ‘clear’ and ‘translucent’ or ‘opaque’ are often highly subjective. What is acceptable for one observer is possibly not acceptable for another observer. It is possible...

Rectangular Tubing Upgrades in Clarity

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...

Oval PETG Tubing

We have extruded oval tubing for over a decade, but this is the first time we extruded it in our PETG (Provista) formulation. PETG has some advantages over CAB in that it is FDA and NSF compliant with food contact, and our employed formula has passed the NFPA 286...

Clear CAB Tubing At Monticello

One of Monticello's most memorable features is the Great Clock, designed by Thomas Jefferson and built by Peter Spruck in 1792. It is fully functional today. The clock, with both an interior and exterior face, (and loud chime) dictated the schedule of the entire...

Blue Star Bends

For top-of-the-line clarity in bends, nothing comes close to our Provista (PETG) line with monitored air packing. For clarity one has to control the packing material. This method was developed for a line of retail-coffee-house bends. Nothing is clearer, and this...

Provista Bends And Sleeves

We recently filled an order with specialty bends for Provista (PETG) UVO. This clear, transparent conveyance system is UV stabilized and FDA/NSF approved. We also supplied sleeves for the order. In order to maintain NSF standards, the sleeve is thick-walled. This...

Space Station Bend

Do you need an off-the-charts bend of transparent tubing? How about a 14° 200" R (no tangents)? We received an interesting call this week. A school is preparing a model of a space station to be displayed at NASA. Our little part in this was to scale down a 12 ft...

Forty Years of Vibracore Sample Tubing

For decades, Busada has been extruding sample core tubing for oceanographic research; and off-shore bottom sampling in the search for submerged oil reserves. The clear tubing may be removed intact from the pipe, preserving the original spatial relations of the sample...

Tees, Wyes, And Branches

Often in pneumatic conveyance, one needs to bring two lines together. In such cases, transparency offers obvious advantages; a transparent connector immediately shows a visual of the area most likely to jam. At Busada we have made various Wyes and other connectors for...
