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...

Frosting Stratus Tubing

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...

Busada Provista Stratus LED Tubing

Eastman Chemical has a Spectar Blog. Spectar, is a copolyester used for many applications, one of them is for LED light diffusion and transmission. Q: I know Eastman Spectar™ copolyester well in the retail market, but didn’t know about the offerings in the lighting...

LED Lights Of Uncommon Interest With Stratus Tubing

Our LED tubing was put to a beautiful use with Objects of Common Interest in a Brussels display. The architects chose our line of Stratus tubing (6" OD). The project came to us first in concept, design, and fabrication. The material used to produce these lights is an...

Making A Para-Truncated Cylinder (A.K.A. Train Tunnel)

We were approached by a lighting manufacturer to form a suitable transparent casing and shell for an industrial light. Normally extruding this would be the answer, but the quantity needed did not justify the tooling. So, using a secondary fabrication process, we...

Lighted LED Bend With Proper Annealing

Recently we had a request to make circular and helical small diameter bends for a lighting project. We designed special heaters for the project and made our prototypes with clear, transparent CAB (butyrate). The trick is proper annealing. We not only heat our bends to...

LED Tubing Gets Some Culture

When the noted Adirondack Studios asked for a light diffusive tube for a “fire ring” I had no idea that it would lead to a trip to Chicago and some much-needed culture. All that I knew was that this fire ring was to be used in an opera. It was to be made in 16...

VBS Lighthouse

Grace Bible Church of Catawissa, PA needed a quick lighthouse for VBS. We supplied a 10" OD CAB (butyrate) tube with an extension of Stratus and a 40W LED. Better lighthouses can be found, but this satisfied the need of the moment. So, let the games begin.

Mighty Mite – Custom Rigid Extruded Tubing

Problem: Extrude a heavy-walled small diameter pneumatic tube; in this case the wall area composes 75% of the tubing area. The difficulty comes in maintaining wall uniformity while eliminating “lensing,” uneven cooling, uneven shrinkage (curling) and chatter lines....
