TPU introduction

---

Thermoplastic polyurethane (TPU) elastomers are linear polymers formed by the copolymerization of hard and soft chain segments, which have physical properties such as tensile, abrasion and heat resistance, and elasticity similar to rubber.

Thanks to the excellent product performance, the application fields of TPU are expanding, including daily consumer goods, construction, medical, military, automotive, agriculture and many other fields. New products and applications are also emerging, such as large-diameter hoses (shale gas extraction), charging cables for new energy vehicles, foamed TPU (ETPU) sports shoes midsoles prepared by supercritical foaming process, invisible braces, etc.

Fiber reinforced modified TPU composites

---

TPU has good impact resistance, but in some applications, high modulus of elasticity and very hard material is required. Glass fiber reinforced modification is a common technical means to improve the elastic modulus of the material. Through modification, thermoplastic composites with many advantages such as high elastic modulus, good insulation, heat resistance, good elastic recovery, good corrosion resistance, impact resistance, low coefficient of expansion and dimensional stability can be obtained.

Long glass fiber VS Short glass fiber

---

Compared with the short fiber, long fiber has more excellent performance in mechanical properties. It is more suitable for large products and structural parts. It has 1-3 times higher toughness than short fiber, and the tensile strength is increased by 0.5-1 times.

Thermoplastics VS Thermosets

---

Thermosets: when heated for the first time, they can soften and flow, and when heated to a certain temperature, they produce a chemical reaction a cross-chain curing and become hard, this change is irreversible, after that, when heated again, they can no longer become soft and flow.

Thermoplastic: thermoplastic resin is the main component, and various additives are added to form a plastic. Under certain temperature conditions, plastic can be softened or melted into any shape, and the shape remains unchanged after cooling; this state can be repeated many times and always has plasticity, and this repeated is only a physical change.


Advantages

熱硬化性樹脂: 熱硬化性プラスチックは、加熱されても強度と形状を維持します。このため、熱硬化性プラスチックは永久部品や大きくて強力な形状の製造に最適です。さらに、これらの部品は（脆弱であるにもかかわらず）優れた強度特性を備えており、より高い動作温度にさらされても強度が大幅に失われることはありません。

熱可塑性プラスチック: 熱可塑性プラスチックは最も広く使用されているプラ​​スチックであり、通常、高い耐薬品性と耐熱性を備え、変形しにくい高強度の構造を備えています。熱可塑性樹脂を主成分とし、各種添加剤を加えて作られています。熱可塑性プラスチック製品は、誘電率と誘電損失が非常に低く、優れた電気絶縁性を備えており、高周波および高電圧の絶縁材料に適しています。
