This cork & neoprene blend material is very resilient, has good oil resistance, and is excellent for use with water. Being a highly compressible material, it is ideal for many applications, including air and refrigeration compressors. NCA45 seals well at low bolt torque, and flange pressures, and at temperatures up to 248°f (120°C). The small granule size gives the material a visually pleasing pattern making it a great choice for decorative areas as well.
