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.
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.
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.
The PCL-based structure offers a degree of biodegradability under specific conditions, making it a more sustainable choice for environmentally conscious products.
| Application Scene | Recommended Model | Performance Advantage |
|---|---|---|
| Heavy-Duty Wheels & Rollers | M220/56D / M220/95A | High hardness and tensile strength withstand heavy impact and load without deformation, ideal for forklift wheels and conveyor rollers. |
| Industrial Seals & Gaskets | M220/90A / M220/85A | Excellent compression set resistance and oil resistance ensure long-term sealing performance in hydraulic and pneumatic systems. |
| High-Abrasion Lining & Wear Parts | M220/95A / M220/90A | Superior abrasion resistance extends service life in mining equipment, slurry pumps, and chute linings. |
| Flexible Couplings & Shock Absorbers | M220/85A / M220/80A | High elasticity (480-600% elongation) and resilience effectively absorb vibration and impact energy in machinery. |
| Printing & Coating Rollers | M220/90A / M220/85A | Balanced hardness and flexibility provide precise surface contact for uniform ink or coating transfer. |
