Key Features & Technical Highlights
Balanced Hardness & Flexibility
Spans from rigid (95A) to flexible (75A), suitable for products requiring structural support or impact absorption.
Example: T150/95A is ideal for high-stress rollers, while T150/75A is perfect for soft-grip handles.
Superior Mechanical Properties
Maintains solid tensile strength (up to 55 MPa) and significant elongation (up to 520%), ensuring resilience under mechanical stress and repeated use.
Offers good tear resistance and abrasion resistance, contributing to long product life.
Controlled Processability
Pot life ranges from 3.5 to 18 minutes, providing flexibility for various manufacturing processes, from quick casting to detailed molding.
Viscosity at 70°C is optimized for processing, ranging from 650 to 2500 cP, facilitating easy handling and molding.
Eco-Friendly Advantage (Biodegradability)
The PCL-based structure offers a degree of biodegradability under specific conditions, making it a more sustainable choice for environmentally conscious products.

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.
