Extruder Rupture Disks are designed for reliable emergency relief of excess pressure since they instantaneously rupture at a specific predetermined pressure range.
Skylark's model CBP Extruder Rupture Disk is designed specifically for use in plastic extruders. Each assembly consists of a stainless steel body and rupture disk. A rupture disk may be specified for primary relief in applications where pressure buildup can occur so rapidly that the response time of a relief valve is inadequate, such as in a polymerization reaction vessel.
