Do you know the characteristics of TPEE monofilament?

TPEE monofilament is a new material that has attracted attention in the footwear industry in recent years. It can overcome the limitations of TPU and PEBA in some performance aspects, such as low-temperature impact resistance and tear resistance, and even has the potential to form an advantage in cost. It has been applied to some shoes.

Introduction to TPEE materials

TPEE is the English abbreviation of thermoplastic polyester elastomer, which is a type of linear block copolymer containing PBT (polybutylene terephthalate) polyester hard segment and aliphatic polyester or polyether soft segment.
The hard segment and soft segment of TPEE present a two-phase separation microstructure, in which the hard segment is an aromatic polyester, generally terephthalic acid, and the soft segment is most commonly polytetrahydrofuran polyether and aliphatic polyester. Therefore, according to the type of soft segment, TPEE materials can be divided into polyester type and polyether type.

TPEE has many excellent properties. In addition to good toughness, resilience, resistance to bending fatigue, tearing resistance, friction resistance, chemical resistance and other properties, it also has a wide hardness range (25D~85D) and outstanding low-temperature flexibility (-40℃).

Compared with TPU, TPEE has the following characteristics:

At the same hardness, TPEE has a higher compression modulus than TPU, which means that the product has better support. The flexural performance at low temperature and the lower rigidity modulus make it more suitable for outdoor low-temperature environments. At the same hardness, TPEE's ball rebound is 10-20% higher than TPU, and the difference is more obvious in high-temperature environments. The change in rigidity modulus with temperature is lower than that of TPU, which is particularly suitable for use in environments with large high and low temperature differences. The growth in production output and the cost of raw materials are cheaper than TPU, and the price is more competitive than polyether TPU.

Application of TPEE materials in shoe materials

In terms of shoe midsole applications, TPU monofilament yarn is also a popular material. It extends from the midsole foaming parts to the upper yarn, sole, and adhesive, and can completely create a pair of recyclable sports shoes made of 100% TPU.

In fact, the application of thermoplastic elastomers in shoe materials has this trend, not limited to the midsole foaming materials, but a single material to make a pair of shoes, so as to facilitate recycling.

So TPEE is no exception. Its applications cover shoe midsole support accessories, shoelaces, shoe tongues, artificial leather, yarn and other shoe parts, and it also has the potential to create 100% TPEE sports shoes.
