Two key performance requirements for Truck Tire Treads
• Enhanced Tread Wear Resistance Increased Product Durability
VULCAN 1436 based compounds exhibit in comparison with compounds based on VULCAN 6, VULCAN J and VULCAN M: • Higher tensile modulus • High Tensile Strength • Higher Shore A hardness • Higher rebound So, VULCAN 1436 exhibits an excellent reinforcement capability
