PETS |
Pentaerythrityl tetrastearate 季戊四醇四硬脂酸酯 |
55-65 |
Whitish flakes or powders 白色片狀或粉粒狀 |
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能夠改善NBR、HNBR、ACM、CSM等極性橡膠的加工性能,提高填料分散性、膠料流動(dòng)性及脫模性,因其揮發(fā)性低,可用于高溫硫化或連續(xù)硫化等特種硫化工藝。 |
RPA |
combination of zinc salts of higher molecular fatty acids 鋅皂鹽混合物(又稱增塑劑A) |
98 - 108°C |
light brown pastilles 淺棕皂粒狀 |
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. 橡膠增塑劑A為多用途橡膠加工助劑,適用于密煉機(jī),在天然膠和合成膠中均可使用,如NR、IR、BR、SBR、NBR、EPDM等。作為壓出助劑使用,可改善制品質(zhì)量,壓出膨脹率和降低壓出加工溫度。適用于橡膠鞋底材、密封件制品、橡膠履帶的膠料加工,可明顯提高各種橡膠膠料的塑解、分散流動(dòng)、內(nèi)脫模性能。 |
LRPA |
Blend of zinc salts of higher molecular, mostly unsaturated fatty acids 高級(jí)鋅皂鹽混合物(低熔點(diǎn)增塑劑A) |
75-90 |
Light brown pastilles 淺白皂粒狀 |
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.低熔點(diǎn)橡膠增塑劑A與普通的橡膠增塑劑A不同,對(duì)于開煉溫度低至60攝氏度時(shí)也能發(fā)揮有效作用,比如橡膠鞋材或橡膠密封件及橡膠膠管的脫模加工具有明顯的作用,并且不噴霜。本品還能對(duì)所有的填料起到分散劑的作用。由于含有鋅成分,能激活硫化作用。 |
