Fluorocure 5 – Advantages and Benefits

Fluorocure 5 is a new generation cure agent for fluoroelastomers. This type of product is very widely used in developed countries replacing other curatives such as #1 and #3 Curative. Fluorocure 5 contains both vulcanizer and accelerator in a pellet form that is easy to use. Compared with Bisphenol AF/BPP powder blend, Fluorocure 5 has the following advantages

Uniform dispersion in compounds:

Often times Bis AF/PP powder blends are difficult to disperse resulting in visible white particles in compound. Such particles cause the compound to have low tensile strength and elongation. For molded products with complex shape the white particles also reduce the hot tear strength and cause higher defect rate. Fluorocure 5 has a melt temperature of 90°C. Therefore during the mixing process it melts and it is easily dispersed into the compound.

Improved flow properties:

Also because Fluorocure 5 melts at the processing temperature, it acts as a process aid and provides the compound with better flow properties. Fluorocure 5 is very suitable for making products with complicated shapes using injection molding and transfer molding processes.

Higher efficiency:

Undispersed particles of Bis AF/BPP means lower efficiency. Since Fluorocure 5 melts during mixing, excellent dispersion and hence maximum utilization of curing agent is achieved.The pellet form of Fluorocure 5 also reduces loss in the mixing process. Bis AF/BPP powder can be dusty and sucked into ventilation system

User/environment friendly:

Fluorocure 5 is in pellet form and produces minimal dust. On the other hand Bis AF/BPP blend can be dusty during weighing and mixing and is therefore a health hazard to the operator. Compared with #1 and #3 Curative, Fluorocure 5 gives compound superior compression set properties.
