Item Unit standard carbon black N774 Iodine adsorption g / kg 29 ± 6 Common name: non-polluting high modulus semi-reinforcing carbon black. 1. Properties: This product has moderate reinforcing properties, and N762, N772 compared to benzene transmittance slightly higher (about 95%), the structure is slightly higher. Its main feature is the low solvent extraction, do not pollute the rubber. 2. Uses: This product is used in tire carcass, sidewalls, inner tubes, rubber hose, tape. Well the FDA black plastic material process performance, filling volume can be very high: 3. Usage and role. Flexible vulcanizates high, low heat, good dynamic performance.
