This material is UL (Underwriters Laboratories) certified, ensuring its compliance with industry safety and performance standards. PP-130GTA is known for its excellent mechanical properties, ease of processing, and superior chemical resistance, making it a versatile choice for manufacturers across different sectors.
1. Material Composition and Properties
Polypropylene (PP): The base polymer is polypropylene, a widely used thermoplastic known for its excellent chemical resistance, low density, and good balance of mechanical properties.
Glass Fiber Reinforcement: The "130-GTA" designation indicates the presence of 30% glass fiber reinforcement, which enhances the material's stiffness, strength, and dimensional stability, making it suitable for load-bearing applications.
UL Certification: PP-130GTA is UL certified, meaning it has undergone rigorous testing to ensure it meets safety standards, particularly in terms of flame resistance, electrical insulation, and material durability.
2. Applications
The XINYITE PP-130GTA material is ideal for a wide range of applications, especially in areas where strength, durability, and safety compliance are critical. Key applications include:
Electrical and Electronic Enclosures: The material's excellent electrical insulation properties and UL certification make it suitable for producing housings, enclosures, and other protective parts in electrical and electronic devices.
Industrial Components: PP-130GTA is also used in various industrial applications, including machinery parts, brackets, and fittings, where high mechanical performance and chemical resistance are required.
Consumer Goods: The material's ease of processing and aesthetic finish make it an ideal choice for durable consumer products, such as home appliances, storage containers, and furniture components.
3. Injection Molding Suggestions
When working with XINYITE PP-130GTA material, certain injection molding practices should be followed to optimize the quality and performance of the final products:
Drying: Although polypropylene generally has low moisture absorption, it is still advisable to dry the material before processing, especially if it has been exposed to a humid environment. Drying at 80-100°C for 2-4 hours is typically sufficient.
Molding Temperature: The recommended barrel temperatures for injection molding PP-130GTA are between 180-240°C, depending on the specific mold design and part geometry. The mold temperature should be set at 30-60°C to ensure proper cooling and part ejection.
Injection Pressure: Moderate injection pressure is typically required to fill the mold effectively, especially when dealing with complex geometries or thin-walled parts. This helps in achieving good surface finish and minimizing defects like sink marks or voids.
Screw Speed: A moderate screw speed is recommended to ensure uniform melting of the material while avoiding excessive shear, which can degrade the material and lead to poor mechanical properties.
Cooling Time: Proper cooling time is crucial for maintaining dimensional stability and avoiding warping or shrinkage. The cooling system should be designed to provide uniform cooling across the entire part.
Post-Processing: Parts made from PP-130GTA may not require significant post-processing, but if additional finishing is needed, processes like trimming or annealing can be performed to improve the final product's quality.
Conclusion
XINYITE Brand PP-130GTA is a versatile and robust material that offers excellent mechanical properties, chemical resistance, and UL certification, making it suitable for a variety of demanding applications. By following appropriate injection molding guidelines, manufacturers can achieve high-quality parts that meet the specific requirements of automotive, electrical, industrial, and consumer goods applications.
