Noval BD1288 Soap

NOVAL BD1288 offers an alternative route in reducing material costs. It can behave as a primary/ secondary accelerator and as an activator component to replace stearic acid which is conventionally used in rubber recipe. Very low dosage of NOVAL BD1288 is sufficient to provide the effectiveness but with no compromise on physical properties vis-a-vis conventional method of compounding containing zinc oxide and stearic acid as an activator component.

The using of NOVAL BD1288 is not restricted to NR compounds only. It can also be used in synthetic rubber compounds such as SBR, chlorobutyl , butyl, EPDM and nitrile rubbers with different recipes. Results indicated that it can replace stearic acid and act as a secondary accelerator as projected by the reduction in cure time ( Figure 7-11 ).

NOVAL BD1288 was also tested for its efficacy in black compounds ( Table 6 ) and the processing characteristics are illustrated in Figures 5 and 6 in terms of scorch. The result shows that NOVAL BD1288 provides the activator /accelerator effect by reducing the scorch and cure time.

The vulcanizate properties of the black compound depicted in Table 7 indicates its ability to replace the conventional activator component stearic acid and secondary accelerator without affecting the vulcanizate properties.

In this study, formulations as given in Table 6 were used. Figure 5 shows the effectiveness of NOVAL BD1288 as a secondary accelerator as proven by the fact that the scorch time is much shorter than a compound containing TMTD as a secondary accelerator. The advantage of using NOVAL BD1288 os further elucidated in Figure 6.

It is an incomplete exercise if the new material is not evaluated as a mono-accelerator ( Table 4 ). The scorch time reduces with increasing levels of NOVAL BD1288 ( Table 5 ).

The ability of NOVAL BD1288 to cause crosslinking of rubber chain is illustrated by the rheometer traces obtained @160

Under research since 1994, Hemo Asia Sdn Bhd now introduces Noval BD1288 a new activator/ accelerator in rubber vulcanization.
