| Product Data | ZDTP is mainly used as an EPDM vulcanisation accelerator and has the advantage of no frosting, fast vulcanisation and low cost. |
| Application | 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. In order 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. |
| Storage | It should be stored in a cool, dry, well-ventilated place at a temperature below 50°C. Packaged products should be kept out of direct sunlight and are valid for 1 year. |
| Packing | 25kg plastic woven bags, paper-plastic composite bags, kraft paper bags or 20/200kg drums. |
