HighLine Polycarbonate LLC: Polycarbonate – Flammability
http://highlinepc.blogspot.com/2014/08/polycarbonate-flammability.html
Monday, August 11, 2014. Polycarbonate – Flammability. The most common method of defining polycarbonate sheet flammability properties is UL.94; this test method was developed by Underwriters Laboratories in the USA. There are multiple levels of flammability:. HB – A piece of the material to be tested is held horizontally, a flame is applied to one end of the material for 30 seconds. When the flame is removed the material must extinguish before the flame travels 75mm along the material. As can be seen, th...

Tuesday, November 15, 2011. Birefringence, Photoelasticity, Anisotropic Materials, Iridescence and the Rainbow Effect - Part 3. In the final blog post of this trilogy we will discuss Iridescence and how it can cause a rainbow effect on abrasion resistant coated Polycarbonate sheet. We will also discuss how the rainbow effect can be minimized. Iridescence is the rainbow or oil slick type pattern that often appears on the surface of a Polycarbonate sheet particularly under artificial lighting conditions.

HighLine Polycarbonate LLC: Drying Polycarbonate sheet
http://highlinepc.blogspot.com/2012/03/drying-of-polycarbonate-sheet.html
Tuesday, March 20, 2012. Polycarbonate sheet readily absorbs moisture from the air. Eventually the water content will reach 0.2% by weight. In most applications this water content is not a problem, however, in applications where you need to process the sheet above a temperature of 250F, this water can vaporize within the sheet during processing and lead to small bubbles forming. As little as 0.05% water can cause these bubbles. In general the Polyethylene or paper masking is not a very good moisture barr...

Tuesday, January 10, 2012. How thick does Transparent Armor need to be? A question that we are frequently asked is how thick is transparent armor made from glass and polycarbonate? The answer to the question depends on what level of threat the armor needs to stop. As we discussed in a recent post, the Kinetic energy of a bullet can be calculated if the weight of the bullet and the speed of the bullet are known using the following formula:. Thickness (mm) = [0.0085 x Energy (Joules)] 10. Of course, just m...

HighLine Polycarbonate LLC: Anti Glare Coatings explained
http://highlinepc.blogspot.com/2012/05/anti-glare-coatings-explained.html
Thursday, May 10, 2012. Anti Glare Coatings explained. Anti-glare coatings are different to anti-reflective coatings. Anti-glare coatings are generally produced using an abrasion resistant hard coat with small particles in the coating to give a matte surface. This matte surface stops light being reflected from the sheet surface back to the viewer so that the user's view is not obscured by glare from lighting or the sun. The answer depends on what you are trying to view. If you are trying to view some...
