Carbon Black N660 (GPF)
CAS Number: 1333-86-4
Carbon Black N660, classified as General Purpose Furnace (GPF), is a large particle size, low structure carbon black offering low heat build-up, good flexibility, and excellent dynamic properties. Its low modulus contribution makes it preferred in compounds requiring high elongation, good fatigue resistance, and low heat generation under dynamic loading, such as tire sidewalls, vibration mounts, and flexible industrial goods.
