company news about EMA Jinke Explores Thermoplastic Polyurethane TPU Applications

Imagine a material that combines the elasticity of rubber with the toughness of plastic, while offering versatile processing options. This is thermoplastic polyurethane (TPU), a high-performance polymer with exceptional properties and wide-ranging applications.

TPU, short for thermoplastic polyurethane elastomer, is a polymer that occupies the middle ground between rubber and plastics. It is synthesized through the polymerization of diisocyanates, chain extenders, and small molecule polyols. By adjusting the raw material ratios, manufacturers can produce TPU products with varying hardness levels, elastic moduli, and physical properties to meet diverse application requirements.

The material's standout characteristics include exceptional wear resistance, high elasticity, superior strength, and excellent processing capabilities, making it indispensable across multiple industries.

TPU boasts remarkable tensile strength, tear resistance, and abrasion resistance, maintaining stable performance even under harsh conditions. Its high elasticity allows quick recovery after deformation, coupled with excellent impact resistance.

TPU products span an extensive hardness spectrum from Shore A 60 to Shore D 80+, enabling customization for specific needs. Softer TPU grades offer rubber-like tactile qualities, while harder variants demonstrate impressive rigidity and load-bearing capacity.

The material withstands UV radiation, ozone exposure, and various chemical agents, ensuring longevity in outdoor applications. It maintains excellent resistance to oils, solvents, acids, and alkalis.

TPU accommodates multiple manufacturing methods including injection molding, extrusion, blow molding, and calendering, offering high production efficiency and cost-effectiveness. Its favorable melt flow properties enable fabrication of complex geometries.

Certain TPU formulations feature recyclability, aligning with sustainable development principles. Recycling initiatives help conserve resources and reduce environmental impact.

The material's versatility spans nearly all industrial and consumer sectors. Key application areas include:
