Halogen free flame retardant (HFFR)
In the past 15 years, various halogen-free flame retardants (HFFR) have been used in thermal plastic engineering plastics. At the same time, halogen free flame retardant (HFFR) is also the main flame retardant system for such polymers. This is largely due to its environmental advantages and the need to meet the ultimate use of security in the context of security.
On the limited use of certain harmful substances in electrical and electronic equipment directive (RoHS), the registration, evaluation, authorization and restriction of chemicals (REACH) and the discarded electrical and electronic equipment (WEEE) regulations such as promoting the development of no halogen flame retardants (HFFR). All three are European regulations, but many other countries now have similar rules.
There is also a law that has played a role in the new standard for pan-european rail compliance, EN 45545, which will take effect in March 2016. This new standard clarifies test methods, quotas, and a series of requirements for parts (r1-r26). Such as R22 and R23 may dictate the connector, the maximum application of series of materials requirements (first internal applications, secondly external application), limited oxygen index (LOI), smoke density and toxicity of any gas. The risk level hl1-hl3 indicates the severity of the test, with HL3 ranking the highest.
There are no fire retardation standards and regulations for automotive components and systems, except for the internal components of the federal motor vehicle safety standards (FMVSS) 302. However, as the industry's emphasis on vehicle safety has improved, it is clear that there will be new requirements (FMVSS 302 is just a spread test of fire). Foam, film and textiles all require the addition of flame retardants to pass the test, and injection molding is usually not required.
In the recent ten years, the national fire protection association (NFPA) released the fire and dangerous guide (NFPA 556), to extend a train personnel during a fire can be used to escape from the vehicle or accept rescue time, thus improve the security of passenger vehicles. It is still just a guiding document, but it affects the government and industry, and it is likely to push carmakers to improve and increase the use of flame retardant plastics in key components.
Isopropylphenyl Phosphate(IPPP50)Use:
Isopropylphenyl Phosphate, Flame Retardant IPPP50 This Product Is Compatible With Vinyl Chloride, Nitrocellulose, Synthetic Resin And Natural Resin, Etc. Because Of The Above Advantages, Reofos Series In Industrial Production Is Widely Used: PVC Film As Flame Retardant Plasticizer, Reofos Increase In The Amount Of Oxygen Index Increased, Enhanced Flame Retardant. In The Rubber Industry Can Be Used As Chloroprene Rubber And Rubber Flame Retardant Plasticizer; In Other Industries Can Be Used As Lubricants With Extreme Pressure Additives And Digestion Of Cellulose Paint, Resin, Phenol Resin And Other Flame Retardants.
Isopropylphenyl Phosphate, Flame Retardant IPPP50 Use Is Also Applicable To Fabric Coating, Circuit Boards, Flooring, Textiles, PVC, Phenolic Resin And Other Fields.
Flame-retardant polyamide is mostly used in electrical and civil engineering and transportation. Cars have gradually become the key development area, because the battery shell, connectors, sensors and (now demand is less, but there may be demand in the future) material such as fuel cell separator for mechanical, electrical and flame retardant properties and so on have higher requirements. Automobile application accounts for about 45% of the overall market of injection molding polyamide, but most of them are not flame retardant.
Electronic and electrical applications account for more than 25% of the total market of injection molding polyamide, and most of them have strict flame retardant requirements (usually UL 94 V0), and are increasingly inclined to require thickness of 0.4mm. General industrial and engineering applications (such as circuit breakers and switches) account for nearly 10 per cent of the market, and these applications are also required for flame retardation.
New applications such as LED lighting, pv and automotive electronics are the greatest opportunities for the development of halogen-free flame-retardant polyamide. In particular, the LED application also requires that the materials have anti-uv characteristics. The Internet of things and the computer server market for cloud computing is also a development opportunity.
Polyamide 6 and 66 are semi-crystalline polymers, known for good mechanical properties and good thermal stability, and are competitive in price. Of course, flame retardant is not an inherent feature of polyamide 6 and 66. The heat release rate of polyamide is higher than that of polycarbonate but less than polyester in the case of engineering plastic polycarbonate and polyester. In order to pass industry test standard, the required flame retardant dose is also affected.
In many applications, polyamide requires glass fiber reinforcement, which has a negative effect on its flame retardant properties (as do other polymers), since fiberglass is like a wick. Therefore, although unreinforced polyamide may reach UL94 V2 flame retardant grade, the same polymer with fiberglass enhancement may not be able to qualify.
