LGF40 TPU Material
What is LGF40 TPU?
LGF40 TPU is a high-performance thermoplastic polyurethane composite material, containing approximately 40% long glass fibers internally. This material is designed to fill the performance gap between traditional elastomers and rigid engineering plastics, maintaining elastic properties while significantly enhancing structural strength and durability.
Unlike ordinary short glass fiber reinforced materials, LGF40 TPU adopts a long glass fiber structure. During the processing, it can retain a higher fiber length, thereby forming a more stable internal support network. This structure enables the material to perform better in terms of bearing capacity, impact resistance, and dimensional stability, while still retaining the flexibility and resilience of TPU itself.
Material Structure and Composition
The LGF40 TPU is mainly composed of the following three parts:
TPU matrix (thermoplastic polyurethane)
Provides flexibility, wear resistance, and excellent chemical resistance.
Long glass fibers (about 40%)
Provides high rigidity, high strength, and excellent fatigue resistance.
Functional additive system
Includes coupling agents, stabilizers, and processing aids, used to enhance the bonding force between the fibers and the matrix and optimize processing stability.
The long glass fibers form a kind of framework-like structure within the material, which can effectively disperse stress and reduce the risk of crack propagation. It performs particularly stably in complex stress environments.
Core Performance Features
LGF40 TPU features the following key characteristics:
- The balance between high rigidity and flexibility
- Excellent impact resistance (especially in dynamic environments)
- Outstanding fatigue resistance
- Good dimensional stability
- Excellent wear resistance
- Good chemical resistance
These properties enable it to maintain stable performance even under repeated stress, long-term use and in complex environments, and it can solve the problem of brittleness while achieving a good balance between strength and toughness.
Application Case
Automobile intake air duct system
Customer pain point: Materials tend to crack in vibration environments, resulting in a short service life.
LGF40 TPU can effectively absorb vibration and shock. The material is less likely to develop crack propagation under repeated stress, thereby significantly enhancing the durability of the component.
Industrial conveying system components
Customer pain point: Frequent friction leads to severe wear and high maintenance costs.
The LGF40 TPU material maintains its wear resistance while enhancing structural strength, making it more stable in environments with load-bearing and friction.
Portable electronic device protective case
Customer pain point: Drop impact causes the shell to crack or the internal structure to be damaged.
LGF40 TPU not only maintains rigidity but also has buffering capabilities. It can absorb energy at the moment of impact and quickly return to its original shape, thereby protecting the internal components.
