Plastic Sheets Flammability

Precautions should be taken to protect the material from flames and high heat sources.

Plastic sheets flammability.

5va 5vb v 0 v 1 v 2 and hb. There are six different flammability ratings under ul 94. Lexan 9034 is an uncoated sheet and the standard grade of lexan sheet. The flammability of plastics is determined by utilizing various test methods from underwriters laboratories fmvss astm and iso.

Ul 94 the standard for safety of flammability of plastic materials for parts in devices and appliances testing is a plastics flammability standard released by underwriters laboratories of the united states. Flame retardant polycarbonate sheets ac plastics is proud to offer makrolon low flammability lf plastic sheeting solutions. The standard determines the material s tendency to either extinguish or spread the flame once the specimen has been ignited. Fire rated polycarbonate sheet is a flame inhibiting uv stable plastic sheeting and glazing product that is virtually unbreakable.

Trm manufacturing fr610 weatherall 6 mil flame retardant white poly plastic sheeting 1 box of 100 feet long by 10 feet wide 4 1 out of 5 stars 12 65 99 65. Here is a breakdown of the three most common. The standard determines the material s tendency to either extinguish or spread the flame once the specimen has been ignited. Access panels may be required for evacuation and venting of rooms glazed with acriglas sheet.

Grades of kydex sheet are available that have outstanding flammability properties including ul 94 v 0 rating and class 1 a rating astm e84. Benefits of kydex thermoplastic sheet for retail fixtures kiosks and transaction surfaces. Using ul 94 to determine the flammability of plastics specifically ul94 entails exposing a test sample to an open flame for one minute and measuring the characteristics of its reaction. Lexan 9034 which is the lexan general purpose polycarbonate sheet is listed as flame resistant by the manufacturer.

Ul 94 is now harmonized with iec 60707 60695 11 10 and 60695 11 20 and iso 9772 and 9773. This paper can only touch on some of the most important topics for the designer and engineer in an effort to give some broad guidance. When looking at the flame ratings for plastic materials commonly molded to fabricate enclosures structural parts and insulators found in consumer electronic products 5va 5vb v 0 v 1 v 2 and hb a material classified as 5va or 5vb is subjected to a flame ignition source that is approximately five times more severe than that used in the v 0 v 1 v 2 and hb tests. Numerous internationally recognized test exists to test the flame retardancy of a given material.

The flammability and burning response of plastics is a complex subject and these properties vary greatly with the type of plastic and the detailed additives used in the plastic. Generally speaking the same fire precautions that are observed in connection with the use of any ordinary combustible material should be observed when handling storing or using acriglas. Flammability acriglas sheet is a combustible thermoplastic and is classified as a slow burning plastic.
