PC toughening agent versus in large in 进行一 product processing 时都会 use to modified product, that for/regarding upper already 经越 越 more modified toughened product in 选购时应该 need attention/notes what 事项呢?

    increase agent types type 越 越 more, make less 初入行 plastics products enterprise in selection increase agent 时候不知道该 how to selection. lower to large introduction lower selection increase agent need attention/notes which 事项:

    1, increase agent and resin versus property, generally 说, additives has and 树 脂间 has good versus property: can make additives long 期, stability, uniform 存杏 于 products in, has 效 发挥 its function, if versus property good, easy 发生 “出汗” or “喷霜” phenomenon, has versus property good, products requirements 不太严格, still can has relatively versus property, filling agent and 树腊间 versus property 极差, need filling agent degree small, still can basic meet/satisfy products property can requirements, most good use coupling agent or surface active property agent 处理, can separation its function.
 
    2, increase agent resistant property I additives loss main/primary through strip/profile 途径挥发, and main/primary and additives molecular weight large small, in in solvent understanding degree and in resin in understanding degree has 关.

    3, increase agent for processing conditions property: certain resin processing strip/profile relatively 苛刻, processing temperature degree high, 时应考虑 选 additives separation understanding, additives for mold, equipment has 否腐蚀 function.

    4, products applications for additives made 约: different applications products for additives odor, property, electrical property, property, thermal properties and other has requirements.

    5, increase agent combined in function and versus for resistant function, in resin system in, has its in types additives generate “协同 function 〃, ratio mono use certain types additives, 发挥效果 function large more. 缤纷PC toughening agent 认 is is combined 不当, types additives generate “ for resistant function ”削 low types additives function, make certain types additives function, this especially attention/notes, 如炭黑 and amine type or type oxygen agent use generate for resistant function.
