-
Wide Hardness Range
From rigid (95A) to flexible (75A), catering to applications requiring high load-bearing capacity or shock absorption.
Example: T120/95A withstands heavy pressure in die-cutting, while T120/75A absorbs vibration in conveyor rollers.
-
Superior Mechanical Properties
Tensile strength up to 60 MPa (T120/90A) and elongation up to 720% (T120/75A), ensuring durability under stress.
High elasticity reduces deformation under cyclic loading, extending service life.
-
Controlled Processability
Pot life ranges from 3.5 to 8.5 minutes, allowing flexibility in molding and casting processes.
Viscosity optimized for uniform flow during curing (e.g., 1100–2100 cP at 70°C).
-
Tailored Curing Systems
Compatible with MOCA (for high-performance grades) and E300 (flexible grades), enabling precise cross-linking density control.
| Application Scene | Recommended Model | Performance Advantage |
