INTRODUCTION

TS GFF is a high-performance tail-seal grease specifically designed for the first filling of tail-seal brushes on tunnel boring machines. Injected and filled between the wire brushes and the shield prior to initial excavation, it remains adhered to the wire brushes throughout the entire tunnelling process, providing maximum protection for the brushes.

TS GFF is supplied in 260 kg metal drums. It is suitable for the standard press plate pumping system installed in TBMs.

ADVANTAGES

TS GFF offers many advantages such as:

Excellent resistance to water

Anti-washout

Excellent adhesion to metal surface

Excellent cohesion to itself

TS GFF exhibits exceptional viscosity while maintaining its pumpability. When utilised in conjunction with HERSHENG TS GFF pumping equipment, it ensures the perfect filling for tail-seal brushes.

TS GFF is fully compatible with HERSHENG TS G60. When used together, they ensure long-lasting sealing and protection throughout the consultation period, preventing leakage incidents.
