四、性質(zhì)：
HA-8商品名為HVA-2,為黃色或棕色粉末，可溶于二氧六環(huán)，四氫呋喃和熱丙酮中,不溶于石油醚，氯仿、苯和水中。
五、作用及配合：
HA-8作為多功能橡膠助劑，在橡膠加工過程中既可做硫化劑，也可做過氧化物體系的助硫化劑，還可以作為防焦劑和增粘劑，即可適用于通用橡膠，也適用于特種橡膠和橡塑并用體系。還可解決了銅導線和銅電器因接觸含硫硫化劑生成硫化銅污染發(fā)黑的難題。用量：作為防焦劑為：0.5-1.0份。作為硫化劑為2-3份，改善壓縮變形為1.5份，提高粘合強度為0.5-5.0份。
六、包裝:
內(nèi)襯PE薄膜的PE袋，凈重10 kg或25kg紙板桶。
Properties HA-8’s trade name is HVA-2. Yellow or brown powder, It is soluble in dioxane, tetrahydro furan and hot acetone, and insoluble in petroleum ether, chloroform, benzene and water.
Application HA-8 is a multi-function rubber agent. In the rubber process industry, it can be used as either curing agent, coagent for peroxide curing system or anti-scorcher and adhesion promoter. In addition to general-purpose rubber, it can be applied to special purpose rubber and rubber-plastic blends.It can solve the problem of copper wire blackening due to copper sulfide resulting form the reaction between copper wire and sulfur containing curing agents.
Usage: anti-scorcher, 0.5-1.0 phr; curing agent 2-3 phr; For improving compression set, 1.5-2.0; For improving adhesive strength, 0.5-5.0 phr.
Packing: PE bag lined with PE film.Net weight:10kg/bag or 25kg/drum.
