Fireproof ABS filament is a fireproof material tested according to UL94 and IEC 60695-11-10. It is ideal for coating elements that may pose a fire source material.
All typical plastics have low flame resistance, hence arose the ABS Smartfil FIREPROOF which is a flame retardant or self-extinguishing in order to provide high levels of security in the environments of both daily life or work as technical parts. FIREPROOF ABS is an additive ABS to delay the spread of fire and extinguishing finish without producing plastic drip.
Underwriters Laboratories (UL) is an independent organization that provides testing and product safety testing and certification. His UL94 test and qualification procedures for determining the flammability of thermoplastic are generally accepted standard in virtually everyone.
This test measures the burning time of a sample of polymer fixed vertically (the thickness specified in the test) after they have made contact with the flame of a Bunsen burner for 10 seconds. The V0, V1 and V2 tests determine the degree of self-extinguishing polymer.
UL94 vertical burning material is classified as V0 when the fire is extinguished in 10 seconds without dripping, as V1 when the fire is extinguished in 30 seconds without dripping and V2 when the fire is extinguished in 30 seconds with dripping.
Safety tests carried out in the presence of fire with Fireproof ABS filament with a piece of wall thickness of 1.5mm are able to extinguish the flame in less than 30 seconds without producing plastic drip so it would match the category V1 according to UL94. Tests with pieces of Fireproof ABS with 2.1mm thick or greater are capable of self-extinguishing the flame in less than 10 seconds without causing dripping of plastic material, which corresponds to the category V0 according to UL94.
Therefore, the ABS FIREPROOOF is ideal for coatings or covers to protect such electrical circuits or any risk of generating element fires.
In short, this FIREPROOF ABS filament can be eligible for the highest category of self-extinguishing according to UL94 as long as the thicknesses are more than 2.1mm.
In addition the ABS FIREPROOF is additive to reduce the effect warping and cracking. The warping effect occurs due to the shrinkage of the plastic as it cools affecting the first layer of the piece off of the printer dock. cracking and warping effect is similar to but in the intermediate layers.
