Compounding technology for Thermoplastic Elastomer(TPE/TPU/TPR)
Compounding technology for thermoplastic elastomers (TPEs), thermoplastic polyurethane (TPU), and thermoplastic rubber (TPR) involves a similar process to rubber compounding. But thermoplastic elastomer compounds have some important differences.
The process typically involves the following steps:
Mixing:
The raw materials, including the polymer, fillers, plasticizers, and other additives, are combined in a mixing chamber, such as a twin-screw extruder, and mixed together until they are evenly distributed.
Melt processing:
The mixture is then subjected to heat and pressure, which melts the polymer and activates any curing agents or cross-linking agents.
Cooling and solidification:
The melted mixture is then cooled and solidified to form a solid elastomeric material.
Testing:
The final product is then tested to ensure that it meets the desired specifications for properties such as hardness, tensile strength, elongation, and resilience.

There are several factors that must be considered when compounding TPEs, TPU, and TPR, including the specific properties required for the final product, the processing conditions, and the cost and availability of raw materials. Fillers, plasticizers, and other additives may be added to improve properties such as flexibility, durability, and heat resistance.
Unlike rubber compounds, TPEs, TPU, and TPR are thermoplastic materials, meaning they can be melted and re-molded multiple times without losing their elastomeric properties. This makes them highly versatile and easy to process, allowing for greater flexibility in design and manufacturing.
Overall, the compounding technology for TPEs, TPU, and TPR is a complex and specialized process that requires a deep understanding of the properties of the materials involved and the desired end-use applications.
