HA-8 HVA-2 PDM

中文名： N，N’-間苯撐雙馬來酰亞胺

英文名： N，N’-m-phenylene dismaleimide

CAS NO.：3006-93-7

不溶于石油醚、氯仿、苯和水中，熔點195℃以上。

指標主要參數：

外觀 黃色或棕色粉末

熔點　≥ 195℃

平均粒徑 40um

1、HVA-2作為多功能橡膠助劑，在橡膠加工過程中既可作硫化劑，也可作過氧化物體系的助硫化劑，還可以作為防焦劑，既適用于通用橡膠，也適用于特種橡膠和橡塑并用體系。

2、在天然膠中，與硫黃配合，能防治硫化返原，改善耐熱性，降低生熱，耐老化，提高橡膠與簾子線粘合力和硫化膠模量。用于載量輪胎肩膠、緩沖層等橡膠中，可解決斜交載重輪胎肩空難題，也可用于天然橡膠的大規格厚置品以及各種橡膠雜品。

3、HVA-2在氯丁橡膠、氯磺化聚乙烯橡膠、丁苯橡膠、丁腈橡膠、、異戌二烯橡膠、丁基橡膠、有、溴化丁基橡膠、丙烯酸酯橡膠、硅橡膠和橡塑并用膠等特種橡膠中，作為輔助硫化劑，能顯著改善關聯性能，提高耐熱性，適用于高溫硫化體系，降低壓縮變形十分明顯，還能減少過氧化物的用量，防止膠料在加工過程中的焦燒，提高膠料和簾子線及金屬的粘合強度。

4、HVA-2屬無硫硫化劑，用于電纜橡膠，它可代替噻唑類、秋蘭姆等所有含硫硫化劑，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黑的難題。

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。

N, N’ – m – Phenylenedimaleimide (HA-8)

Multifunctional rubber additives HA-8, which during rubber processing of curing agent can be done to help peroxide curing agent system, but also can be used as anti-coke agent and tackifier, you can apply to general-purpose rubber, also applies to specialty rubber and rubber and plastic and use system; for the truck tire shoulder gum rubber cushion layer. Solve the problems of bias truck tire shoulder space, but also can be used for large-sized thick natural rubber products and various rubber sundry goods; as an auxiliary curing agent, can significantly improve crosslinking performance, increase heat resistance, suitable for high-temperature curing system, reducing compression permanent deformation is very obvious, but also reduce the amount of peroxide to prevent the plastic material during processing of the coke burning to improve rubber and tire cord and metal adhesion strength. 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.
