Beitel The use of plastic building materials in commercial and residential construction has dramatically increased due to improved plastic material performance, efficient use of technologies in new applications, and the need for lightweight, durable materials for .
UL Recognition and Flammability Ratings. RTP Company offers support in material selection, design optimization, and plastic processing that can aid you in obtaining product certification from Underwriters Laboratories. Additionally, as a participant in UL's Client Test Data Program we can expedite UL Recognition and issuance of "yellow cards" for our custom compounds.
Jan 24, 2014· The most popular testing is the UL 94 small-flame test. The UL 94 small-flame test is a hands-on approach. They burn the plastic horizontally. If the piece of plastic burns horizontally, it earns a UL 94-HB rating which means it catches fire and burns horizontally, the least flame retardant.
Firewire® Flame Retardant ABS 3D Printing Filament, 1kg Reel. Firewire® FR-ABS is made using a premium UL94 V-0 rated ABS. Our FR-ABS is high-gloss jet black and supplied on 1kg reels (2.2 lbs.), sealed in vacuum bags to keep them dry. This filament is ideal for applications that require UL94 V-0 self-extinguishing characteristics.
propensity of a substance to ignite easily and burn rapidly with a flame, is one indicator of fire hazard. Figure 1 shows the relationship between two measures of flammability: heat release capacity (section 4.6) and flame resistance (section 5.4) versus the truckload price of commercial polymers.
Jun 05, 2014· UL94 Flammability Ratings on Polycase Electronic Enclosures. June 5, 2014. The UL 94 flame rating is a safety standard widely popular in the world of plastics materials. The tests conducted measure flammability characteristics of the enclosure and determine the plastic material's propensity to either extinguish or spread a flame once ignited.
Special flame retardant grades exist which pass several severe flammability tests. Polystyrene is rated safe to use up to 165°F. It begins to soften at approximately 212°F, and as more heat is …
