Shanghai Daoqin Plastics Co., Ltd.

    world upper hard polyvinyl chloride (PVC) use amount growth and plastics toughening agent , toughening agent processing modifier day development has 密切 关系. toughening agent （toughener） is can increase agent film flexibility property material 质. certain hot solid property resin agent, ring oxygen resin, aldehyde resin and saturated and polyester resin agent solid rear elongation low, property relatively large, bonding 部位承受 outer force very easy generate cracks, speed expand 展, 导致胶层 cracking, resistant fatigue, can as is structure bonding use.  

    1, toughening agent formulation analysis is use methods analysis product formed separation, for formed separation 进行定 property amount, also its formulation formed process, material R&D field/area “反 toward engineering ”; through ABS toughening agent formed separation analysis generally using/adopting large micro 谱图（ light 谱, color 谱, can 谱, 质谱, hot 谱） comprehensive analysis method, combined related industry experience, analysis combined also formed formulation; formed separation analysis more used for chemical industry material formulation made, formulation 改进, and production process in industrial diagnosis issues solution, solution enterprise in R&D production in issues.

    2, toughening agent is tool has reduce composite/compounding material property and improve/increase composite/compounding material impact resistant property can, resistant 寒, high temperature resistance and other property can types plastics additives. can separation is active property toughening agent and non active property toughening agent type, active property toughening agent is its separation upper has can and resin reaction active property 基团, it can formed structure, increase separation flexible 链, from improve/increase composite/compounding material impact resistant property can. non active property toughening agent is type and resin very good versus solvent, 但不参 and chemical reaction toughening agent.
