PETS

Pentaerythrityl

tetrastearate

季戊四醇四硬脂酸酯

55-65

Whitish flakes or powders

白色片状或粉粒状

PETS it can effectively prevent the sticking of the compounds to the rubber rolls,and has positive effect regarding the flow and demoulding properties with the injection and mould pressing process ,suitable for ACM，H-NBR，EVA，CSM，ECO/CO，IIR/CIIR/BIIR，CR,etc.

PETS能够改善NBR、HNBR、ACM、CSM等极性橡胶的加工性能，提高填料分散性、胶料流动性及脱模性，因其挥发性低，可用于高温硫化或连续硫化等特种硫化工艺。

RPA

combination of zinc salts of

higher molecular fatty acids

锌皂盐混合物（又称增塑剂A）

98 - 108°C

light brown pastilles

浅棕皂粒状

Excellent peptizing effect in NR and IR upwards of 60°C, can decrease the viscosity of compounds based on NR resulting in an easier processing, which leads to higher extrusion rates, better dimensional stability and a stable die swell. RPA provides a good dispersion of the fillers and rubber chemicals in the compound. Used in tire, molded and extruded articles of all types, hard rubber.

橡胶增塑剂A为多用途橡胶加工助剂，适用于密炼机，在天然胶和合成胶中均可使用，如NR、IR、BR、SBR、NBR、EPDM等。作为压出助剂使用，可改善制品质量，压出膨胀率和降低压出加工温度。适用于橡胶鞋底材、密封件制品、橡胶履带的胶料加工，可明显提高各种橡胶胶料的塑解、分散流动、内脱模性能。

LRPA

Blend of zinc salts of

higher molecular, mostly unsaturated fatty acids

高级锌皂盐混合物（低熔点增塑剂A）

75-90

Light brown pastilles

浅白皂粒状

Low melting-point grade processing promoter,more effective in NR and IR rubber at a mill temperature as low as 60 °C. Suitable for low temperature continuous mixing and open mill mixing for tire, molded and extruded articles of all types, hard rubber.低熔点橡胶增塑剂A与普通的橡胶增塑剂A不同，对于开炼温度低至60摄氏度时也能发挥有效作用，比如橡胶鞋材或橡胶密封件及橡胶胶管的脱模加工具有明显的作用，并且不喷霜。本品还能对所有的填料起到分散剂的作用。由于含有锌成分，能激活硫化作用。
