GF40 TPU Composite

40% Long Glass Fiber TPU Composite

What is GF40 TPU Plastic Pellet?

40% Long Glass Fiber TPU material (LGF40 TPU) is a kind of high-strength composite engineering plastic material with thermoplastic polyurethane (TPU) as the matrix and 40% long glass fiber as the reinforcing filler. Compared with chopped glass fiber (SGF), long glass fiber is generally 5 to 25mm in length. During processing, it maintains a longer fiber morphology, which can form a stronger skeleton support structure and endow the material with higher tensile strength, flexural modulus and impact resistance. 

GF40 TPU material is a thermoplastic elastomer that combines the properties of plastics and rubber, featuring excellent flexibility, wear resistance, oil resistance and low-temperature performance.  

It outperforms ordinary glass fiber chopped strand reinforced TPU (SGF) materials in terms of structural strength, heat resistance, dimensional stability, etc., and has extremely high practical value in structural applications such as automobiles, industry, and rail transit. 

Is GF40 TPU compound a good material to use?

Against the backdrop of continuous innovation in modern industrial materials, composite materials are gradually replacing traditional metals and single plastics, becoming the preferred materials in many high-performance fields. GF40 TPU material not only integrates the inherent flexibility, wear resistance and chemical stability of TPU, but also achieves a leapfrog improvement in structural performance through high-proportion glass fiber reinforcement. It can be called a good material. It also has many excellent performances.

Key Advantages:

 High strength and high rigidity: 40% glass fiber reinforcement significantly enhances tensile strength and flexural modulus

 Excellent wear resistance: Retains the original high wear resistance of the TPU substrate

 Heat distortion temperature increase: It still maintains excellent dimensional stability in high-temperature environments

 Good impact resistance: It maintains rigidity while having a certain degree of toughness

 Good processing performance: Suitable for injection molding and some industrial technology processes

GF40 TPU material is particularly suitable for replacing metals or engineering plastics in automotive interior and exterior structural components, balancing lightweight and structural stability.
