Pearlstick 45-50/29
Pearlstick 45-50/29, developed by Lubrizol, is an elastic, aromatic, linear polycaprolactone copolyester-based thermoplastic polyurethane (TPU) designed specifically for the production of solvent-based adhesives in the footwear industry. This TPU grade offers a unique combination of properties tailored to meet the demanding requirements of footwear adhesive applications, ensuring strong, durable bonds between plasticized PVC materials.
Key Features and Benefits
- Extremely High Crystallization Rate: Pearlstick 45-50/29 is characterized by an extremely high crystallization rate, facilitating rapid bond formation and ensuring strong initial adhesion between plasticized PVC substrates. This property enhances manufacturing efficiency and productivity by enabling fast curing times in adhesive applications.
- Medium-Low Thermoplasticity Level: With a medium-low thermoplasticity level, this TPU grade strikes a balance between flexibility and stiffness, providing optimal adhesive performance for bonding plasticized PVC materials. The formulation maintains its integrity and bond strength across a wide range of temperatures, ensuring reliable performance in diverse environmental conditions.
- Good Hydrolysis Resistance: Pearlstick 45-50/29 exhibits good resistance to hydrolysis, ensuring long-term bond durability and reliability in footwear applications exposed to moisture or humid environments. This property enhances the longevity and performance of adhesive bonds, contributing to the overall quality and durability of footwear products.
- Excellent Heat Resistance: The TPU grade offers excellent heat resistance, allowing adhesive bonds to maintain their strength and integrity even when subjected to elevated temperatures during footwear manufacturing processes or in service. This feature ensures reliable performance and durability of bonded footwear components under thermal stress.
- Improved Freeze Resistance: Pearlstick 45-50/29 demonstrates improved freeze resistance, providing resilience and durability in footwear applications exposed to cold temperatures or freezing conditions. The TPU grade maintains its bond strength and integrity even in challenging environmental conditions, ensuring reliable performance in diverse climates.
Recommended Applications
Pearlstick™ 45-50/29 is specifically recommended for the production of solvent-based adhesives used in bonding plasticized PVC to plasticized PVC materials in the footwear industry. It is ideally suited for various footwear applications, including sole attachment, upper assembly, and general shoe bonding processes. The TPU grade’s advanced properties ensure strong, durable, and resilient adhesive bonds, contributing to the quality, comfort, and longevity of footwear products.
