Key Features & Technical Highlights
-
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.

Frequently Asked Questions
What is the target application for your prepolymer?
Please specify your industry and end-use, e.g., footwear (soles), industrial rollers, seals, or other elastomeric components. This helps us recommend the optimal formulation and curing system.
What are your specific performance requirements?
Please indicate your target values for hardness (Shore A/D), tensile strength, elongation at break, and abrasion resistance. Our standard M240/60D offers excellent specifications, but we can customize to meet your needs.
Do you require a specific curing agent or system?
We typically recommend BDO or other curatives. Let us know if you have a preferred curative or if you need technical assistance in selecting the best one for your process.
What is your required sample quantity for testing and evaluation?
We provide free samples (typically 1-2 kg) for R&D purposes. Please specify the quantity needed to conduct your initial trials.
What certifications or quality standards are mandatory for your project?
Our products are SGS and ROHS certified. Inform us if you need additional certifications like ISO, REACH, or specific industry standards.
What is your estimated monthly or annual consumption volume?
Providing your forecasted volume (kg/month or tons/year) allows us to structure the most competitive pricing and ensure supply chain stability.
What is your target price per kilogram?
While we strive to offer the best value, sharing your budget helps us find a solution that meets both your performance and cost requirements.
Do you require technical support during the product development or production phase?
Our technical team can provide guidance on formulation optimization, processing parameters, and troubleshooting. Let us know your level of support needed.
