Plastic Resin Flame Rating

At times, we would be asked about a flame rating for the plastic material or compound we either purchase or make here locally.  We thought that information was generally lacking or not easily found, so we took the initiative to make it readily available for everyone to learn about.
 
UL 94 is the flame rating test standard.  
 
“HB” is one classification, and is the most basic.  Most plastics will have an HB rating.  In fact, we joke that is standards for “happily burning”.
 
5VA is the highest flame rating a material can have, and indicates the material self extinguishes.  Below are all the classifications within the UL94 test:
 
  • HB: slow burning on a horizontal specimen; burning rate < 76 mm/min for thickness < 3 mm or burning stops before 100 mm
  • V-2: burning stops within 30 seconds on a vertical specimen; drips of flaming particles are allowed.
  • V-1: burning stops within 30 seconds on a vertical specimen; drips of particles allowed as long as they are not inflamed.
  • V-0: burning stops within 10 seconds on a vertical specimen; drips of particles allowed as long as they are not inflamed.
  • 5VB: burning stops within 60 seconds on a vertical specimen; no drips allowed; plaque specimens may develop a hole.
  • 5VA: burning stops within 60 seconds on a vertical specimen; no drips allowed; plaque specimens may not develop a hole.

Advantages of Plastic over Metal

How designers across multiple industries are reducing costs and increasing profits by incorporating plastic instead of metal in new product designs.

Elk Grove Village, IL. 2/25/15  Ask any plastic manufacturer if a part should be designed in plastic or metal and they will give a list of reasons why plastic is always the way to go. Ask any metal manufacturer the same question and you will get a list of reasons why metal is superior. In our experience, as we talk with clients during their initial design phases, we have found there is a general lack of knowledge and many misconceptions surrounding the benefits of engineering-grade plastic resins.
