NR
NR is friction material suitable for medium duty, wet and dry industrial applications.The material consists phenol resins. NR is fully cured and suitable for bonding and riveting. It success may be attributed to its hardness with gives it good wear and tensile strength while still achieving average and stable friction levels.NR is a material special for hydraulic applications because this material doesn’t contain metallic particles.
