What are the general differences? The The
LS said the two are modified plastic, that is, the material may itself is not good flame retardant, but by adding flame retardant, you can make the material to achieve a certain level of flame retardant, in other words, that is, most of the material added Flame retardants have flame retardant properties, but this should not be the answer to the landlord want it fundamentally speaking, the flame retardant test material is to see the material off the fire after the extinguishing time, or material burning time, according to material Different, different sizes, different testing methods, of course, there are many natural flame retardant materials, such as PVC (PVC) without adding flame retardant, it is extinguished from the fire. (PEEK), polyetherimide (PEI), polyphenylene sulfide (PPS), polyphenylene sulfone (PPSU), polyphenylene sulfide (PPS) , Polyether sulfone (PES), polyvinylidene fluoride (PVDF) and liquid crystal polymer (LCP) and so on. PBT itself is not very good flame retardant, halogen-free flame retardant can also be modified, the so-called halogen-free flame retardant or halogen-containing flame retardant, it means that the use of the taste is a bit of fat, Flame retardant, halogen-containing combustion in the general produce toxic gases, but the flame retardant effect is very good, the price is low. As for how you mention the difference, do not know what you want to distinguish, I feel you are not like to ask how the difference between the plastic resistance is not flame retardant, the general is a direct test friends, fundamentally speaking, and molecular structure has a great relationship, such as PVC (Polyvinyl chloride) containing Cl, burning produce HCl, so the flame retardant effect is good, but the HCl toxic, look at the polymer aspects of the bar, I hope to help you
Flame retardant grade PP, flame retardant PP, flame retardant PE, flame retardant PB, flame retardant PBT, flame retardant PC, flame retardant Burning PC / ABS alloy, and now there are still halogen flame retardant, halogen-free flame retardant research a lot, but the product stability and flame retardant effect has yet to be improved. Flame-retardant material testing methods are: commonly used flame-retardant material testing methods, including horizontal and vertical combustion, oxygen index method, NBS smoke box method, thermal analysis, cone calorimeter method. The simplest is the direct burning about, intuitive to see is from the fire to try Ding Bai shares of fat Karma mixed with the stem that is put out or continue to burn, burning time.
