Can polyethylene and flame retardant masterbatch be flame retardant?

It does not mean that polyethylene plus flame retardant masterbatch can be flame retardant, but it can reach a certain flame retardant level. What flame retardant level is usually reached, such as UL94-V0 or V2.

One of the table changes to the UL944 series is the UL945V test. This test is used to compare the combustion characteristics of different samples, but focuses on whether the specimen is burned through. During the test, a 125 mm long flame is applied from one corner of the specimen for a total of 5 times, with 5 seconds apart each time.

Record the time of nominal combustion and smoldering, and observe whether the sample is burned through. If the open and smoldering time of the sample is 60s in total, and the sample is not burned through, the test material is grade 5A. If the open and smoldering combustion of the sample is less than 60s, but the combustion is 5vb.

V-0 level.

The open combustion time is less than 10s, the total open combustion time (10 ignitions) is less than or equal to 50s, no melt droplets ignite the absorbent cotton, the sample is not burned to the fixture, and the smoldering time is less than or equal to 30s after the ignition source is removed.

V-1 level.

The open combustion time is less than 30s, the total open combustion time (10 ignitions) is less than or equal to 250s, no melt droplets ignite the absorbent cotton, the sample is not burned to the fixture, and the smoldering time is less than or equal to 60s after the ignition source is removed.

V-2 level.

The open combustion time is less than 30s, the total open combustion time (10 ignitions) is less than or equal to 250s, no melt droplets ignite the absorbent cotton, the sample is not burned to the fixture, and the smoldering time is less than or equal to 60s after the ignition source is removed.

The thickness of the specimen is.

There are not many flame retardant PE. Generally, there are more flame retardant PP, and it is best to find a granulation factory to extract the grain, otherwise it will be uneven.

Flame retardant masterbatch, also known as flame retardant masterbatch, is one of the flame retardant products that perform well in plastics and rubber resins today, flame retardant mother wheel sensitive material (masterbatch) is based on the basis of flame retardant through the organic combination, modification and synergistic effect of a variety of flame retardant components, and through the twin or triple screw extruder through the sale of mixing, extrusion, granulation and a granular product If my answer is helpful to you, please also give a thumbs up (in the lower left corner of the evaluation), look forward to your like, Your efforts are important to me, and your support is what drives my progress. Finally, I wish you good health and a good mood!

Summary. Hello dear <>

If you need to improve its flame retardant performance, you need to add a certain amount of flame retardant.

Whether the flame retardant can be achieved by the flame retardant of the plastic.

Hello dear <>

If you need to improve its flame retardant performance, you need to add a certain amount of flame retardant to attack the cherry blossoms.

In the process of processing plastic products, flame retardants must be added. Flame retardants have the property of preventing substances from burning and burning, and are mainly suitable for plastics with flame retardant needs, delaying or preventing the combustion of plastics, especially polymer plastics. Make it ignite for a longer time, ignite self-extinguishing, and be difficult to ignite.

Flame retardant is one of the important additives in plastic processing, which can make plastics have flame retardancy, self-extinguishing and smoke elimination, thereby improving the safety performance of plastic products. In terms of production and usage, flame retardants have become the second largest plastic additives after plasticizers, and the global consumption of flame retardants has exceeded 1 million tons. The plexus experiment proves that UL-94V-0 high flame retardant plastics can be prepared without adding flame retardants, using inorganic fiber reinforcement, mineral powder filling, scientific matching of various components, and forming a flame-retardant structure.

It ensures low smoke, low toxicity, no corrosion, low cost and good physical and mechanical properties and processing properties, and expands the use range of phenolic plastics. I wish you a happy life! I hope my kernel spike is helpful to you.

Summary. Hello, kiss <>

It is impossible to achieve flame retardant effect without flame retardant in plastics. A flame retardant is a chemical substance that can stop or slow the spread of flames during the combustion of plastics, thereby preventing fires from occurring or mitigating fire damage. If the plastic is not flame retardant, then when it encounters an ignition source, it will easily burn and spread quickly, leading to the occurrence of fire.

Therefore, if a plastic needs to be flame retardant, flame retardants must be added to the production process. There are many types of flame retardants, and different flame retardants can be selected according to different needs. For example, phosphorus-based flame retardants, brominated flame retardants, nitrogen-based flame retardants, etc.

These flame retardants can play a role in the combustion process of plastics, effectively preventing the spread of flames and improving the flame retardant properties of plastics.

PVC plastic does not release flame retardant can achieve HB flame retardant, right?

Dear, PVC plastic may not be able to achieve HB flame retardant rating without flame retardant. HB flame retardant grade is a standard for the flame retardant performance of plastic materials, which usually means that in a horizontal state, the material can extinguish the flame by itself during the combustion process, and will not drip in front of the mold shed and during the combustion process, and the combustible material will ignite the cardboard. However, PVC plastic is a flammable plastic, which is prone to dripping and toxic fumes during combustion without flame retardants, which is harmful to human health and the environment.

Therefore, in order to meet the requirements of fire safety and environmental protection, PVC plastics usually need to add flame retardants to improve their flame retardant performance to meet the standards of HB flame retardant grade or higher.

Flame retardant plastics are plastics that can inhibit or delay combustion and are not easy to burn in their own wells.

It is widely used in construction, electrical appliances, fire protection, transportation, national defense and other fields. At present, fire accidents at home and abroad are still showing a high incidence trend, and the use of flame retardant plastics can effectively reduce the occurrence of fire accidents, especially with the implementation of various laws, regulations and standards, it can be expected that during the "14th Five-Year Plan" period, flame retardant plastics still have a large room for growth.

National Standard for Flame Retardant Grade of Plastics:

1. The lowest grade in the HB94 standard. For samples 3 to 13 mm thick, the burning rate is less than 40 mm/min; Samples less than 3 mm thick with a burning rate of less than 70 mm per minute; Or extinguish in front of a 100mm sign.

2. After V-2 conducts two 10-second combustion tests on the sample, the flame is extinguished within 60 seconds. Incendiary objects can fall.

3. After V-1 conducted two 10-second combustion tests on the sample, the flame was extinguished within 60 seconds. No incendiary material can be dropped.

4. After V-0 performed two 10-second burning tests on the sample, the flame was extinguished within 30 seconds. No incendiary material can be dropped. <>
