用途

1、HVA-2作为多功能橡胶助剂,在橡胶加工过程中既可作硫化剂,也可作过氧化物体系的助硫化剂,还可以作为防焦剂,既适用于通用橡胶,也适用于特种橡胶橡塑并用体系。

2、在天然胶中,与硫黄配合,能防治硫化返原,改善耐热性,降低生热,耐老化,提高橡胶与帘子线粘合力和硫化胶模量。用于载量轮胎肩胶、缓冲层等橡胶中,可解决斜交载重轮胎肩空难题,也可用于天然橡胶的大规格厚置品以及各种橡胶杂品。

3、HVA-2在氯丁橡胶氯磺化聚乙烯橡胶丁苯橡胶丁腈橡胶、、异戌二烯橡胶、丁基橡胶、有、溴化丁基橡胶丙烯酸酯橡胶、硅橡胶和橡塑并用胶等特种橡胶中,作为辅助硫化剂,能显著改善关联性能,提高耐热性,适用于高温硫化体系,降低压缩永久变形十分明显,还能减少过氧化物的用量,防止胶料在加工过程中的焦烧,提高胶料和帘子线及金属的粘合强度。

4、HVA-2属无硫硫化剂,用于电缆橡胶,它可代替噻唑类、秋兰姆等所有含硫硫化剂,解决了铜导线和铜电器因接触含硫硫化剂生成硫化铜污染发黑的难题。

用量

作为防焦剂为0.5-1.0份,作为硫化剂为2-3份,改善压缩变形为1.5份,提高粘合强度为0.5-5.0份。

包装

复合袋净重10㎏

桶装,净重20/25kg

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.
