Thermoplastic Rubber (TPR)

Thermoplastic Rubber (TPR), also known as Thermoplastic Elastomer (TPE), is a unique material that combines the flexibility of rubber with the processability of plastics. This hybrid material consists of two distinct polymer phases: one that acts as a solid at normal temperatures and another that remains fluid, enabling it to be molded like plastic when heated. The interaction between these phases gives TPR its elastic properties at room temperature and allows for efficient processing, making it a versatile alternative to traditional rubbers. TPEs are categorized into general-purpose and engineering types, with over 30 varieties developed since the 1930s. Early examples include polyurethane TPE from Germany, styrene-butadiene-styrene block copolymers from the U.S., and olefin-based TPEs that became popular in the 1970s. Today, TPEs cover a wide range of applications, from automotive parts to medical devices, thanks to their excellent mechanical properties, recyclability, and cost-effectiveness. One of the key advantages of TPE is its ability to be processed using standard thermoplastic equipment such as injection molding and extrusion. This eliminates the need for time-consuming vulcanization processes, significantly reducing production times and energy consumption. Additionally, TPE waste can be easily recycled, contributing to environmental sustainability. Despite its benefits, TPE has limitations, particularly in heat resistance compared to conventional rubbers. However, ongoing research and development have led to improved variants such as hydrogenated SBS (SEBS) and SEPS, which offer better weathering and thermal stability. These materials are now widely used in high-performance applications, including automotive components, construction, and consumer goods. In the automotive industry, TPEs are increasingly replacing traditional rubbers in bumpers, seals, and interior parts due to their lightweight and durability. In the footwear sector, TPEs are used in soles and midsoles, offering comfort and resilience. Their use in medical devices, packaging, and electronics further highlights their versatility. Overall, TPE represents a significant advancement in material science, bridging the gap between plastics and rubbers. As technology continues to evolve, TPEs are expected to play an even greater role in sustainable manufacturing and innovative product design.

Eyelet Dies

Zonglan Hand Tools for eyelets consist of piercing and attaching hand toolsets.

This manual set is designed to be used with a hide face mallet. It is good for piercing material and attaching curtain eyelets afterward. Not all hand tools are the same and it is not easy to find such a highly qualified hand tool for attaching curtain eyelets in today`s world.

Though these tools are designed for low-volume eyelet application projects, Zonglan Hand Tools are professionally designed and produced with advanced technology for decades of problem-free use. Zonglan Hand Tools are made of Stainless Steel to increase their resistance to oxidation. Their surface is specially treated for metal hardening for stronger durability against harsh hammer usage.

Zonglan Hand Tools are designed in such a manner affording the use of minimum force with maximum comfort. In addition, thanks to its precision, the eyelet application quality of Zonglan Hand Tools is far better than the application quality of its ordinary competitors.

Our hand tools sets are available for 6mm,10mm and 12mm Easy Apply Zonglan eyelets and are suitable to attach them onto various substrates, including tarpaulin, drapery and home textile.
