It has a crystallinity of 80%–90%, a softening point of 125–135℃, and can be used up to 100℃. Compared to low-density polyethylene, HDPE has better hardness, tensile strength, and creep resistance. It also offers superior wear resistance, electrical insulation, toughness, and cold resistance. HDPE has excellent chemical stability—it is insoluble in organic solvents at room temperature and resistant to acids, alkalis, and various salts. Long Glass Fiber Glass fiber reinforced plastics (GFRP) are made by adding glass fibers and other additives to pure plastics, which significantly extends the material’s application range. These reinforced materials are commonly used for structural parts in products made from PP, ABS, PA66, PA6, HDPE, PPA, TPU, PEEK, PBT, PPS, and others. Advantages High heat resistance: Glass fiber is heat resistant, so reinforced plastics can withstand much higher temperatures, especially nylon-based plastics. Reduced shrinkage and improved rigidity: Glass fiber restricts polymer chain movement, decreasing shrinkage and significantly improving rigidity. Improved impact resistance: Reinforced plastics resist stress cracking and have much higher impact strength. Enhanced mechanical strength: Tensile strength, compressive strength, and bending strength are greatly improved. Flame retardancy: Addition of glass fiber and other additives reduces combustibility; most reinforced plastics cannot be ignited. Datasheet Contact Us

What is PA6 (Nylon 6)? PA6 (Polyamide 6), commonly known as Nylon 6, is a semi-crystalline thermoplastic engineering plastic containing amide groups (-CONH-) in its molecular backbone. It is one of the most widely used engineering polymers in the world. PA6 is produced from caprolactam and is available in various grades including PA6, PA66, PA610, etc., depending on the monomer structure. Among them, PA6 and PA66 are the most commonly used in industrial applications. PA6 offers excellent mechanical strength, wear resistance, and processability, making it widely used in fibers, engineering plastics, and films. Properties of PA6 PA6 provides a balanced combination of mechanical and chemical performance, including: High tensile and compressive strength Excellent toughness and fatigue resistance Good wear and abrasion resistance Strong resistance to oils, fuels, and most organic solvents Good electrical insulation properties Easy processing and good moldability However, PA6 also has some limitations such as high moisture absorption, dimensional instability, and reduced impact performance at low temperatures. Limitations of PA6 High water absorption affects dimensional stability Poor UV resistance and long-term thermal oxidation behavior Property variation under humid environments Processing sensitivity to moisture content Why Reinforce PA6 with Long Glass Fiber? To overcome the limitations of neat PA6, reinforcement with long glass fibers (LGF) is widely used. This is a common physical modification method to significantly enhance material performance. By incorporating long glass fibers into the PA6 matrix, the following properties are greatly improved: Mechanical strength and stiffness Dimensional stability Heat resistance Fatigue performance Load-bearing capability Applications of PA6-LGF 30% long glass fiber reinforced PA6 is widely used in high-performance structural components, including: Power tools: housings and structural parts Automotive industry: engine components, structural brackets, interior and exterior parts Industrial equipment: mechanical parts and housings Its fatigue strength can reach up to 2.5× higher than unreinforced PA6, making it ideal for demanding applications. Processing Guidelines (PA6-LGF 30%) The addition of 30% long glass fiber significantly reduces shrinkage to approximately 0.3%, compared to 1.0–1.5% for neat PA6. Higher fiber content generally leads to lower shrinkage, but may also increase surface fiber exposure and processing challenges. Recommended processing notes: Recycled material usage should be controlled within 25% Material must be properly dried before processing Excessive reprocessing may affect mechanical performance and color stability Mold design should consider fiber orientation and flow balance Post-cooling in warm water helps reduce warpage and internal stress Customers & Production Certifications

PPA (Polyphthalamide) is polyphthalamide.PPA is a kind of thermoplastic functional nylon with both semi-crystalline structure and non-crystalline structure. It is prepared by polycondensation of phthalic acid and phthalenediamine. It has excellent thermal, electrical, physical and chemical resistance and other comprehensive properties.

Throughout the plastics industry, PEEK is widely recognized as one of the leading high-performance polymers (HPP). While metals have traditionally dominated industries such as automotive, aerospace, oil & gas, and medical devices, PEEK materials are rapidly transforming the market with lightweight and high-strength alternatives. What is PEEK Material? PEEK (Polyether Ether Ketone) belongs to the family of aromatic polyketone polymers, also known as Polyaryletherketone (PAEK). It is one of the world's most advanced thermoplastic engineering materials. Research on PEEK began in the 1960s, and the material was first commercialized by Imperial Chemical Industries (ICI) in 1981. Chemically, PEEK is a semi-crystalline linear polymer that combines excellent mechanical strength, high heat resistance, chemical resistance, wear resistance, and dimensional stability. Compared with traditional metals, PEEK materials are lightweight, corrosion-resistant, easy to process, and offer exceptional specific strength (strength-to-weight ratio). Datasheet for Reference Key Advantages of PEEK High Heat Resistance Continuous operating temperature up to 260°C (500°F), suitable for extreme thermal environments. Chemical Resistance Resistant to fuels, oils, hydraulic fluids, solvents, and harsh chemical environments. Mechanical Strength Excellent stiffness, fatigue resistance, and creep resistance over long service life. Flame Resistance High ignition temperature with low smoke emission, widely used in aerospace applications. Recyclable & Reprocessable Can be repeatedly melted and processed with minimal property loss. Electrical Stability Excellent electrical insulation properties, with optional conductive modifications available. PEEK is also non-hygroscopic, radiation resistant, and transparent under X-ray exposure, making it ideal for medical and electronic applications. As a thermoplastic engineering material, PEEK can be processed by injection molding, extrusion, and compression molding using conventional equipment. Today, PEEK is increasingly replacing traditional metals and alloys in demanding applications where lightweight structures, durability, and long-term reliability are required. Applications PEEK materials are widely used in: Automotive components Aerospace structures Oil & gas equipment Medical devices Electrical and electronic applications Industrial machinery parts Contact us for additional application solutions and customized material recommendations. Production Processing Injection molding is one of the most common methods for manufacturing PEEK plastic components. During injection molding, molten PEEK material is injected into a mold cavity under high pressure. After cooling and solidification, the finished part is ejected from the mold. This process enables the production of complex, thin-wall, high-precision components with excellent surface finish and dimensional stability.
