flame retardant PBT and PET(线 property polyester)PBT and PET is types important engineering plastics, widely used in electronics, table/sheet and automotive industrial in, it flame retardant products by use in flame retardant property requirements relatively high parts in. it flame retardant 处理如 lower:

(1) add bromine flame retardant commonly used has bromine ether, bromine polystyrene (PS) (BPS), bromine ring oxygen resin (BER), di (三 bromine oxygen 基)乙烷 and other.

举例 讲: add 10%-15% bromine flame retardant, 3%-5% 三 oxidation can make 含30% glass fiber (GF) PBT达 to UL 94 V-0 grade 别, oxygen index (LOI) can 达27%-29%. use add type flame retardant must need attention/notes in PBT and PET in dispersion property, easy property, and for polyester gloss, machine strong/high degree effect/influence.

(2) add bromine acid ester commonly used is 三(二 bromine 苯基)磷 acid 脂(TDBPPE), due to separation in has Br, P元素, therefore tool has 卤一磷协同效应. in PBT and PET in flame retardant efficiency high.

this need attention/notes is in flame retardant in 常添;三 oxidation 二锑 协效, if as oxygen index (LOI) testing, that 么极限 oxygen index (LOI) has increase, in oxygen testing ring in, Sb and P似乎会 has types versus for resistant function. therefore, use UL 94垂直燃烧 method evaluation system flame resistant property can is most combined 适.

flame retardant PET used as flame retardant fiber and material.

usually has types methods: its is use bromine ring 十二烷 for PET织 material as flame retardant rear 处理. this type of material can as 窗帘, 幕布, 包墙布 and other inner decoration use 布. due to is rear methods 处理, flame retardant easy 渗出, material and flame retardant resistant property color 一.

its is use copolymer flame retardant modified. this reaction type flame retardant mono main/primary is bromine aromatic combined material, 含芳基 oxidation combined material, bromine 代芳香基 oxidation combined material and other. due to is flame retardant formed is poly material separation in 心 一部 separation, therefore tool has flame retardant long 久, good, lightfast and other advantages, is 当今我国PET flame retardant fiber and material main/primary flame retardant methods.
