Frequently asked questions
Fire incidents can lead to safety risks, production losses, unplanned downtime and environmental impacts. Trellex® fire-retardant rubber screening media is designed to help reduce fire propagation risks associated with ignition sources such as welding, cutting, grinding and other hot work activities, while maintaining the operational benefits of rubber screening media.
Yes. Trellex® fire-retardant rubber is designed to self-extinguish and help limit fire spread if ignition occurs. While no material can eliminate all fire risks, fire-retardant screening media can support a broader safety strategy and help reduce the potential for fire propagation within screening circuits.
Metso's fire-retardant rubber compounds are tested according to UL94 V-0, a globally recognized flammability standard. Under UL94 V-0 test conditions, the material self-extinguishes within 10 seconds after flame application and does not produce flaming drips that ignite surrounding material.
Metso continuously develops and evaluates its fire-retardant rubber solutions against applicable regional fire safety requirements and industry standards.
No. Trellex® fire-retardant rubber screening media is designed to provide wear life, flexibility and screening efficiency comparable to conventional rubber screening media, helping operators improve safety without sacrificing performance.
Both materials provide the flexibility and wear resistance associated with rubber screening solutions. The key difference is that fire-retardant rubber is designed to help reduce fire propagation if ignition occurs while still delivering reliable screening performance.
Yes. Trellex® fire-retardant rubber screening media can be installed on both Metso and third-party screens, making it suitable for both retrofit projects and new installations.
Yes. Fire-retardant rubber can be used for screen panels, feedbox liners, discharge liners and side liners. This enables a more consistent approach to managing fire propagation risks throughout the screening process.
Fire-retardant rubber screening media can be used across a wide range of mining and aggregates applications where operators want to improve fire safety while maintaining the operational advantages of rubber screening media. It is particularly relevant in operations where hot work activities or other ignition sources are present near screening equipment.
