        一, flame retardant modified material

        众 周知, 传统材 material generally selection use nitrogen modified material as is flame retardant. this 样做, 红磷会 dry plastics color. in color upper, use can achieve black or color. another, it function effect/influence processing, but also in high temperature and wet ring in use tool has relatively strong/high property.

         in addition, commonly used machine flame retardant large more aluminum, hydrogen oxidation material is 基础, use agent amount versus for relatively high, 不但严 heavy made plastics processing properties —— especially is injection molding, also effect/influence production parts mechanical properties. nitrogen flame retardant main/primary table/sheet ——三 poly amine acid salt, can used for filling polyamide (PA).

         plastics insulation property meet/satisfy production day improve/increase demand, 不, plastics products film thick degree relatively thin, is tool has relatively high electrical strong/high degree need 确认. usually production through micro type and function high degree formed achieve decrease heavy and reduce cost. due to related structure and 越 越 thin thick degree belt/tape high requirements, versus melt flow 指数也 need to achieve and 保障.

         remove 以卤素, and poly amine or its mixed combined material is 基础 “传统” flame retardant modified material, less material company R&D 出不含卤素 non flame retardant system, this engineering plastics also tool has more high machine and electrical property can.

         using/adopting flame retardant plastics products 几乎没 has flame retardant surface phenomenon, is it 们不含 has in low temperature degree lower 即发生 reaction material 质, therefore and 无保护材 material versus ratio, its process parameters separation versus 似.

        二, engineering plastics

        现 in 越 越 more company use has flame retardant new material substitute/replace has material, development utilizing 无卤材 material used for has and new type parts. this material mechanical properties and electrical property can less need to high temperature material using/adopting anti agent property can indicators, as must high 效.

         in addition, certain material amount demand 也出现 极 large different: certain color 特定 部 parts need as amount relatively less, month material demand 仅以千克计算, standards large amount processing material demand 则数以吨计. in various lower need ensure supply ——也 need ensure to more year certification requirements.

        “ electronics product requirements but also property can high, is has for/regarding complex 几何体 need non 常严谨 公差, 二者 权衡 need 一定 灵 active property ”, flame retardant plastics and use high temperature or standards flame retardant material versus ratio, can more good meet/satisfy safety, strong/high degree, design and other requirements. simple as can more 换, but also has different glass fiber content standards polyamide (PA) price more low, this advantages can achieve cost reduce.

        三, anti standards

         remove DIN standards, engineering plastics also according to USA safety 监测实验室 company (UL) requirements testing. rear is USA electrical appliances technology product certification 组织, it made plastics products testing methods different thick degree parts testing is 基础. V-0 for most high anti grade 别, V-1 and V-2 for versus for relatively low requirements.

         in addition, also through Europe standards IEC 60335. standards low pressure “家 use and similar low pressure electrical appliances ” safety requirements. 提交 文 parts must data 详实, equipment electrical strong/high degree and mechanical properties.
