A unique impregnation process has enabled Elfab to develop an environmentally friendly graphite bursting disc.
The company has replaced the toxic and potentially carcinogenic phenolic- and furane-based resins traditionally used the bursting-disc industry with methacrylate-based resins.
The disc has been tested in trials and field tests for more than six months, during which time, Elfab says, its performance has exceeded that of traditionally impregnated graphite. The final lacquer layer applied to the disc is identical to that used previously, ensuring that the disc surface in contact with the process medium remains unchanged.
"There are benefits in this process change for everyone involved," said Russell Trotter, Elfab's operations director. "Elfab has been able to remove a potentially dangerous and environmentally harmful process from its manufacturing operation, while customers now benefit from an environmentally sound product that outperforms traditionally impregnated graphite."
