RAYWAY™ Rubber Accelerator ZBPD

The accelerator ZBPD is a fast rubber accelerator for natural rubber (NR) and EPDM rubber (EPDM). 1-4 PHR (based on 75% ZBPD) can be added for NR and EPDM applications. ZBPD is non-staining and non-discolouring to the product when applied. For EPDM rubber, ZBPD is a non-frosting, low-cost, ultra-rapid accelerator; in natural rubber, ZBPD has a significant anti-vulcanisation reduction effect when combined with thiazole and hyposulphonamide accelerators. As ZBPD does not contain nitrogen in its molecules, it does not produce carcinogenic substances in its application – nitrosamines. To improve the resistance to vulcanisation reduction of rubber products in NR, the right dosage is chosen to achieve a better balance between scorching and resistance to vulcanisation reduction, and the products have good ageing resistance. Due to its non-frosting and non-discolouring properties, it can be used in transparent NR rubber soles. In the vulcanisation system S 1.5, NOBS 1.0, DTDM 0.8 natural rubber, ZBPD-75 0.7 replaces DTDM 0.8, the rubber performance is close, but the ageing performance is better.

Product Data

ZDTP is mainly used as an EPDM vulcanisation accelerator and has the advantage of no frosting, fast vulcanisation and low cost.
