我们 Common PBT flame retardant issues and solution methods?

缺口敏感 property

causes:

PBT separation in ring and 酚基形​‌‌ formed large system, decrease small separation 子涟 柔曲 property, make separation rigid property increase, and property 酚基, carbon 基 存 in make S7子间 function force increase large, separation rigid property 进一步 reinforcement, from tough property very 差.

solution methods:

1. polymerization modified polymerization modified is through copolymer, grafting, 嵌段, crosslinked and other in polymerization process in in PBT separation in new flexible 涟段, make its tool has good tough property.

2. blending modified blending modified is will modifier or high impact strong/high degree material and PBT blending or composite/compounding, make its as is dispersion versus distribution in PBT基体 in, utilizing separation separation versus property or interface function, improve/increase PBT impact property can. in PBT in add reaction property increase agent POE-g-GMA, through GMA and PBT 端狡基 原位 increase reaction, add strong/high interface function force, to toughened 效果.

currently, full large PBT flame retardant market separation is: USA, Europe, Japan and other 亚太 区. in market in, use amount growth most fast is other 国家 区. material 显示, 2006～2010 year, full flame retardant use amount year growth rate is 4.1%, 而亚洲 other and year growth rate is 12.5%.据 forecast, 2008～2014 year, full flame retardant use amount year growth rate can 达4.9%, sales can 达7%, 即2014 year full flame retardant use amount and sales can separation to 2620 and 61 100 million USD （折 combined 人民币400 100 million yuan ）.

due to lower industry chain 转移, inner PBT flame retardant industry development very fast. currently, China flame retardant use amount is 18万～22 10,000 tons / year. 2007～2011 year, China flame retardant use amount year growth 15% left right. understanding, currently market upper flame retardant product main/primary separation is machine flame retardant and has machine flame retardant type. its in, machine flame retardant oxidation 二锑, hydrogen oxidation and other flame retardant system formed; has machine flame retardant bromine 系, nitrogen and 磷系化 combined material is table/sheet flame retardant product. value attention/notes is, tube/pipe flame retardant industry development speed, inner flame retardant product structure combined 理, performance in bromine flame retardant market 份额巨 large. 但2008～2018 year, 随 国 inner bromine price 飞涨, bromine flame retardant by price versus for relatively low flame retardant substitute/replace trend by strong/high 化, bromine flame retardant market 呈现出一定 萎 shrink 状态.
