HDPE Plastic | Long Glass Fiber Reinforced HDPE

What is HDPE?

High Density Polyethylene (HDPE) is a granular thermoplastic material that is non-toxic, odorless, and highly crystalline (80% - 90%). It has a softening point of 125–135°C and can be used at temperatures up to 100°C. Compared with Low-Density Polyethylene (LDPE), HDPE has superior hardness, tensile strength, creep resistance, wear resistance, electrical insulation, toughness, and cold resistance. It also offers excellent chemical stability, being insoluble in any organic solvents at room temperature and resistant to corrosion from acids, alkalis, and various salts.

Long Glass Fiber Reinforced Plastics (LGF)

Long glass fiber reinforced plastics (LGF plastics) are created by adding long glass fibers and other additives to pure plastics. This reinforcement significantly improves the material's mechanical and thermal properties, making it suitable for structural and engineering applications. LGF plastics are commonly used with materials such as PP, ABS, PA66, PA6, HDPE, PPA, TPU, PEEK, PBT, and PPS.

Advantages of Long Glass Fiber Reinforced Plastics

• Increased heat resistance: Glass fibers improve the high-temperature performance of plastics, especially in nylon-based materials.
• Reduced shrinkage and increased rigidity: Fiber reinforcement restricts polymer chain movement, improving dimensional stability.
• Improved impact resistance: Reinforced plastics resist stress cracking and have higher toughness.
• Enhanced strength: Tensile, compression, and bending strength are significantly improved due to the high-strength glass fibers.
• Flame retardancy: Addition of fibers and additives reduces flammability, making most reinforced plastics non-ignitable.
