main features:

1.The friction coefficient is always greater than 0.25 under various working conditions,it can satisfied the using requirement of mine hoist.
2.High mechanical strength,tested contrast proves that heat resistance ,fusion resistance and abrasion is better than imported filler block that exluding things that damage steel wire rope.
3.Good compatibility of friction grease.On imports,domestic friction grease apply,with domestic LZM friction grease better.
4.Price is affordable.Cost performance is better than imported filler block.It can bring cinsiderable economic benefits for the user.
