LFT Long Glass Fiber Reinforced High Density Polyethylene for Industrial Use

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-HDPE?

Long glass fiber-reinforced HDPE (High-Density Polyethylene) material is a composite made by combining long glass fibers with a high-density polyethylene matrix. 

It offers excellent mechanical properties, significantly improving tensile strength, bending strength, impact resistance, and wear resistance, while increasing rigidity and durability. This material also exhibits good thermal stability, making it suitable for long-term use in high-temperature environments without deformation. 

HDPE itself has excellent chemical stability and resistance to acid and alkali corrosion, and the addition of long glass fibers does not affect these properties, making it suitable for use in harsh chemical environments. 

Additionally, long glass fiber-reinforced HDPE materials have good dimensional stability, effectively reducing thermal expansion and ensuring stability during processing and use.

It is widely used in industrial applications such as automotive components, pipes, containers, and equipment housings.

Despite being a reinforced material, it remains lightweight compared to metal materials, making it ideal for applications requiring lightweight solutions.

FAQ

Q: Does long glass fiber and long carbon fiber injection have special requirements for injection molding machines and molds?

A: There are certainly requirements. especially from the product design structure, as well as the injection molding machine screw nozzle and mold structure injection molding process must consider the requirements of long fiber.

Q. What are the main features and advantages of long fiber reinforced thermoplastics?
A: Compared with traditional short fiber materials, the main features of LFT-G thermoplastic long glass fiber and long carbon fiber are mechanical properties, high impact and tensile modulus, which are more suitable for some large products or structural load-bearing parts. It can do Injection molding, extrusion of sheets, profile pipes, etc.

Q. Are long fiber reinforced composites suitable for other processes besides injection molding?
A: In addition to injection molding, LFT long glass fiber and long carbon fiber can also be used for extrusion of sheets, profiles, pipes and molding, among which injection molding is the most common.
