toughening agent, its 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. that 么, lower small is large introduction toughening agent types type.

what is toughening agent

toughening agent generally has active property 基团, can and resin chemical reaction, solid rear full versus 容, has also need separation versus, obtain relatively toughened 效果, make heat deflection temperature (HDT) or decline micro, impact resistant property can also obvious improvement. low separation liquid or is increase agent material add resin in, although can reduce property, rigid property, strong/high degree, heat deflection temperature (HDT) large degree decline, can meet/satisfy structure bonding requirements, therefore, increase agent and toughening agent is full different.

toughening agent types type

1, type toughening agent: type toughening agent product types main/primary has liquid poly 硫橡胶, liquid poly butadiene 橡胶, 丁腈橡胶, 乙丙橡胶 and 丁苯橡胶 and other.
2, thermoplastic property elastomer: thermoplastic property elastomer is type in normal temperature lower 显示橡胶 elastic property, in high temperature lower also can molding combined formed material. therefore, this category of polymer has and thermoplastic property plastics features, it can as is composite/compounding material toughening agent, also can as is composite/compounding material 基体材 material. this category of material main/primary polyurethane ester type, styrene type, polyolefin type, polyester type, 间规1, 2- poly butadiene type and polyamide (PA) type and other product, currently as is composite/compounding material toughening agent use relatively more is styrene type and polyolefin type.

3, its it toughening agent: suitable for composite/compounding material its it toughening agent also has low separation polyamide (PA) and low separation non active property toughening agent, 如苯二甲 acid ester type. for/regarding non active property toughening agent can is increase agent, it and resin solid reaction.

toughening agent selection 原则

1, ring oxygen resin agent use selection liquid 体丁腈橡胶, 端羧基 liquid 体丁腈橡胶, poly 硫橡胶, liquid silicon 橡胶, polyether, polysulfone (PSU), polyimide (PI), nano carbon acid 钙, nano oxidation titanium and other;
2, aldehyde resin agent can selection 羧基丁腈橡胶, liquid 体丁腈橡胶, polyethylene (PE) alcohol shrink aldehyde, polyether 砜, polyphenylene oxide (PPO) ketone. water solvent property aldehyde resin 以羧基丁腈胶乳, polyethylene (PE) alcohol as toughening agent;
3, fast solid acrylic ester structure agent selection acrylic ester 橡胶, 羧基丁腈橡胶, chlorine 丁橡胶, chlorine polyethylene (PE), ABS resin and other;
4, α-氰基 acrylic ester agent selection acrylic ester 橡胶, ABS, SBS, SEBS and other;
5, saturated and polyester resin agent selection liquid 体丁腈橡胶, polyethylene (PE) alcohol shrink aldehyde, poly acid ethylene and other;
6, aldehyde resin agent can selection poly acid ethylene emulsion, polyethylene (PE) alcohol and other.

toughening agent features

1, normal temperature toughened and low temperature toughened 效果均 very excellent, for its it force property can effect/influence very small, comprehensive property can excellent. in PC（ low M.I.: 10.5, high M.I.: 35） in, add 入2%就 has significantly toughened 效果.

2, in polyester in dispersion very good, and for by toughened material flow property effect/influence very small （ its it grafting type or copolymer type polyester toughening agent, make by modified rear polyester flow property very 差, easy injection ）, effect/influence rear injection. in injection process in toughened polyester for 剪切不敏感, has injection conditions selection.

3, toughened polyester, color can force 极佳, can decrease/reduce color powder add amount.

4, use MBS toughened PC, resistant force cracking property good, meanwhile improvement for water property; make in 135℃ lower hot aging 168 small 时, use 5%MBS toughened PC, its impact decline large.
