Covering Yarn Clutch Facing

● The main materials of this series are ordinary medium-alkali (alkali-free) glass fiber core, core spun yarn by the consisting of chemical fiber wrapping, imported styrene-butadiene rubber 1502, ordinary phenolic resin and organic friction modifier. The products adopt the traditional rubber soaking technology and German engineering which greatly improves its strengths and wear resistance, thus is applied to various types of cars. The main varieties include: FST016, FST018-2, etc.
