BLEND COMPOSITION

It as a wide molecular weight distribution peaking at approximately carbon number

C27/C28giving a fast rate of bloom at low/medium range of temperatures.

It has a wide molecular weight distribution with a high average molecular weight and highly contained isohydro-carbon give a controlled rate of bloom at wide and high rong of temperatures.


 PROTECTIVE EFFECTS
SUNOC gives better results than other ozone protective waxes. The use of high quality special waxes is urgently recommended when products are going to be exposed to ozone at fairly high temperature. It forms a sort of membrane barrier between the rubber article and the environment. This physical barrier is a film of wax which forms on the surface of the vulcanizates. SUNOC is efficient in preventing ozone cracking, particularly under static conditions, but in view of waxes acting, the most important factor is that wax film will remain intact fairly long.
SUNOC 较其它臭氧保护蜡效果更好。当产品在相当高的温度下暴露於臭氧时,迫切需要使用高品质的特殊蜡。它在橡胶制品与环境之间形成一种薄膜屏障。这种物理屏障的蜡膜,在硫化物表面形成。SUNOC在抗臭氧龟裂方面是有效的,特别是在静置条件下。但鉴於蜡的作用,其最重要的因素是蜡膜将可保持相当长的完好无损。

DCP-40C

可用作聚合反应的引发剂,天然橡胶和合成橡胶的硫化剂,合成树脂的交联剂,又可作为橡胶的填充剂可使橡胶色泽光艳,伸长率大,拉伸强度高,耐磨性好,用於生产微孔橡胶(microporous rubber)时,可使其发泡更均匀。
敝公司是由高纯度的99%过氧化二异丙苯(DCP)和微细填充剂按比例均匀加工混合制成。
 
    纯度:≈40%(≈60填充剂)
    外观:白色粉末
    比重:约1.565
    Active Oxygen(活性氧):2.32 min

AFA-2000K除潮剂(消泡剂)

橡胶,塑料等…的制程中会配合使用多种添加剂,内含有水分或混炼过程中吸入的气体而引发气泡产生,表面不良,尺寸不稳定等问题,在添加AFA-2000K后进行适当的配合,能去除原料配合物中的水分或气体,得到无气泡且优良的产品,一般称除潮剂消泡剂.
可获得尺寸稳定,抑制发泡,品质改善减少不良率之优良效果.
本产品於氧化钙(Calcium Oxide)上涂层脂肪酸或氧化后精制的乳剂,可吸收相当於本体重30%以上的湿气(1Kg,AFA-2000K约可除去300g水份),吸收加工橡,塑料制程中配合剂所含有的水分和气体,转变成(Calcium Hydroxide),使制品无气泡且密度均匀.
580°C的高温加热时因可逆反应(reversible reaction)转换成Calcium Oxide不会重新排放,并在橡,塑料内以 Calcium Hydroxide 存在,跟氧化铅,氧化镁一样加硫使用,其性能与效果被证明是相当优秀的,如(CR)氯丁橡胶等合成橡胶作为加硫调制一直都使用氧化镁,但换成AFA-2000K物性也不会产生变化,在CR,PVC配合剂内发挥氯气收容体作用,可防止氯化氢引发之各种副作用.
