Wear Resistant Polyurethane Hydraulic Seals For Tank Track Pads / Military Spare

Polyurethane Two-component Solvent-free Adhesive - UNI-BOND 3000 A/B (2-k system)

This product is a two-component, solvent-free, environmentally friendly adhesive. It has passed SGS certification, European and American ROHS standards, phthalate testing, and Shenzhen’s “Quality Control Standard for Synthetic Material Sports Surface Layers." It is primarily used for bonding various rubber floors, prefabricated running tracks, PVC floors, wooden floors, ceramics, and aluminum honeycomb panels. It is widely applied in industrial and civil settings such as gyms, libraries, sports venues, soundproofing building materials, and more.

Our NDI-PCL Polyurethane Elastomer series represents a cutting-edge fusion of NDI’s (Naphthalene Diisocyanate) exceptional heat resistance and PCL’s (Polycaprolactone) environmental benefits. This series is engineered for demanding applications where thermal stability, mechanical strength, and a degree of biodegradability are required. With a hardness range of 93A to 95A, it is ideally suited for high-performance components in automotive, industrial machinery, and eco-conscious product design.

1. Superior High-Temperature Performance
   • The NDI backbone provides outstanding thermal stability, allowing the material to maintain its mechanical properties in elevated temperature environments where conventional polyurethanes would soften or degrade.
2. High Mechanical Strength & Rigidity
   • Exhibits robust tensile strength (45 MPa) across both grades, ensuring reliable performance under significant mechanical load and stress.
3. Balanced Eco-Friendly Profile
   • The incorporation of PCL polyol offers potential biodegradability under specific conditions, providing a more sustainable option without compromising high-performance characteristics.
4. Excellent Chemical & Wear Resistance
   • Inherent polyurethane properties provide good resistance to oils, greases, and abrasion, extending the service life of components in harsh operating conditions.

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.

• Extreme Environment Suitability: Performs reliably in high-temperature settings, outperforming standard polyurethanes.
• Sustainable Innovation: Offers a unique combination of high performance and environmental responsibility.
• Consistent Quality: Manufactured to precise specifications, ensuring reliable and repeatable material properties.
