What would be the use of having a safety mechanism whose parts are unable to respond to flames? To what extent would we be talking about “security”? One of the basic characteristics that make a device reliable and resistant is that the material with which it is made is the correct one and is adapted to the specifications, regulations or certifications of each sector. In the case of the security sector, this point cannot be left out, since you work with components that are exposed to theft and other damage. Los fireproof plastics are an example of this. Here are the highlights. A multitude of small components are involved in reducers, such as gears, washers, screws, pinions or spindles; therefore, it is vitally important that all of them are Fabricated With the more resistant materials to avoid rapid deterioration, overheating that affects its performance and, even, to ensure the rapid extinction of a flame -flame retardant or flame retardant materials-.Would you like to improve your security mechanisms with self-extinguishing plastics? You are one step away from knowing the rules that affect the flammability of plastics and their self-extinguishing ranges. Let's do it! The use of fireproof plastics is of increasing importance worldwide, due to the replacement of many metal parts with plastic equivalents. Any plastic with UL certification It has been assigned a Self-extinguishing range. For example, an application where this property is very important are cash machines or ticket dispensers, In this way they are prevented situations of vandalism, since having plastics with self-extinguishing properties prevents the spread of fire and makes it difficult to steal money from inside.Underwriters Laboratories is an independent organization that provides product safety tests and tests and their certification. Your procedures UL94 of test and the rating system to determine the flammability of thermoplastics and silicones They are the standard generally accepted almost everywhere in the world.

Different types of UL certifications

• UL 94 Classification V0 · V1 and V2

This test measures the burning time of a vertically fixed polymer sample after it has been contacted with the flame of a Bunsen burner for 10 seconds. The V0, V1 and V2 tests determine the degree of self-extinction of a polymer:

• According to UL 94 (Vertical Burning) Classification V0: Fire is extinguished in 10 seconds without dripping.
• According to UL 94 (Vertical Burning) Classification V1: The fire is extinguished in 30 seconds without dripping.
• According to UL 94 (Vertical Burning) Classification V2: The fire is extinguished in 30 seconds with drip.

It is important to use material certified under the UL 94 grade V0 due to the high level of security which it offers, since it has the best self-extinguishing properties and minimizes fire risks.

• UL 94 HB

This test measures the Burning time of a plastic sample fixed horizontally after it has been contacted with the flame of a Bunsen burner for 30 seconds. According to the UL 94 HB The material is classified HB when a sample of a 3mm thickness It burns at a Maximum speed of 76mm/ minute.

• UL VW-1

The purpose of the UL VW-1 Vertical Wire Flame Test is to qualify the flammability of cables and hoses. In the test UL VW-1 a Tirril burner is used as an ignition source. The sample is applied to the flame for 15 seconds and then removed. The sample is applied to the flame for 15 seconds or when the sample is extinguished, up to a total of 5 applications of 15 seconds. In this way, it is confirmed that If the sample passes this test, it should not burn for more than a minute.

Pay attention to these pure materials:

Flame behavior of plastics:

• Easily combustible plastics: OOPS, OMMA, CA.
• Combustible plastics: PE, PP, SAN, ABS, PET, PBT, POM, PA, PURE.
• Hardly combustible plastics: EP.
• Self-extinguishing plastics: PVC, PC, PPE, MF, PSU, PI.
• Non-combustible plastics: PEEK, LPC, PTFE and fluorinated.
