LFT Long Glass Fiber Reinforced PLA Compounds Injection Molding

Why are your pellets so long? 

What’s the difference between them and short fibers?

Long fiber pellets have several significant advantages over short fiber materials, especially in terms of enhancing the mechanical properties of plastics. Our long fiber pellets are typically used to improve the strength, rigidity, and impact resistance of materials. They are longer than short fiber pellets, allowing for better dispersion in the matrix material and forming a stronger fiber network structure, which significantly enhances the material's mechanical properties, particularly in terms of tensile and bending strength.

Compared to short fibers, long fiber materials have the following distinct differences:

1. Higher strength and rigidity: Long fibers can be more evenly distributed in the material, providing better tensile strength, bending rigidity, and so on.

2. Stronger impact resistance: Long fibers effectively improve the material's toughness and impact resistance, making them especially suitable for industrial products that require high impact resistance.

3. Better stability: Long fiber materials offer better dimensional stability and fatigue resistance, making them suitable for applications with long-term use.

4. Applicaition: long fiber materials are suitable for high-performance applications such as automobiles, electronic devices, and household appliances, while short fiber materials are more commonly used in applications where performance requirements are not as high.

What is LFR-PLA?

Long Fiber Reinforced PLA (LFR-PLA) is an engineering plastic that combines long glass fibers with polylactic acid (PLA) resin.  PLA itself is an environmentally friendly thermoplastic, known for its biodegradability.  However, it has limited mechanical properties, such as strength, toughness, and heat resistance. By incorporating long glass fibers, the performance of PLA is significantly improved, making it suitable for demanding applications.

The addition of long glass fibers enhances the mechanical properties of PLA, such as strength, stiffness, and impact resistance. This makes LFR-PLA ideal for applications requiring high load-bearing capacity.  Additionally, the thermal performance of the material is improved, allowing it to withstand higher temperatures compared to pure PLA. This makes it suitable for automotive parts and electronic device housings.

LFR-PLA also offers better wear resistance and corrosion resistance due to the reinforcing effect of the glass fibers. This makes it suitable for applications with high friction, such as sporting goods and industrial machinery. Moreover, being made from PLA, the material is biodegradable and more environmentally friendly compared to traditional plastics, making it an attractive choice for industries with sustainability goals, such as packaging and medical devices.

LFR-PLA can be processed using conventional plastic processing techniques like injection molding and extrusion, offering good adaptability in manufacturing. It is widely used in industries like automotive, consumer electronics, 3D printing, and eco-friendly packaging due to its combination of high performance and sustainability.
