As a dedicated manufacturer at Shanghai Yunshan Plasticizing Co., Ltd., we are proud to present our PPO GFN30F-780S, a high-performance engineering plastic meticulously formulated with 30% glass fiber reinforcement. This material is engineered to deliver exceptional dimensional stability, making it an ideal choice for precision components that must maintain their shape and tolerances under demanding conditions. We understand the critical need for reliability in industrial applications, which is why our PPO GFN30F-780S is processed to ensure consistent quality, batch after batch. Our commitment from our facility in Shanghai is to provide materials that empower your designs with strength, precision, and long-term performance.
This grade stands out in the PPO/PPE family due to its balanced property profile, significantly enhanced by the glass fiber filler. Below is a detailed breakdown of its characteristics, advantages, and specifications.
Core Product Features & Technical Advantages:
- Superior Dimensional Stability: The 30% glass fiber reinforcement drastically reduces the coefficient of thermal expansion and minimizes warpage or creep over time, ensuring parts retain their precise dimensions across a wide temperature range and under load.
- Enhanced Mechanical Strength: Glass fibers impart high tensile strength, flexural modulus, and stiffness, allowing for the design of thinner, lighter, yet robust components.
- Excellent Thermal Properties: PPO GFN30F-780S maintains good mechanical properties at elevated temperatures, with a high heat deflection temperature, suitable for applications near heat sources.
- Inherent Flame Retardancy: The base PPO polymer combined with this formulation typically achieves a UL 94 V-0 rating, a critical requirement for electrical and electronic housings.
- Good Chemical Resistance: Resists a wide range of aqueous chemicals, acids, and bases, contributing to long-term durability in harsh environments.
- Excellent Electrical Insulation: Maintains stable dielectric properties across various frequencies and temperatures, making it reliable for electrical insulators and connectors.
Key Technical Specifications:
The following table outlines typical property values for PPO GFN30F-780S. Specific values can vary based on processing conditions and part design.

Frequently Asked Questions (FAQ)
-
Q: What is the main advantage of using 30% glass fiber in PPO?
A: The primary advantage is dramatically improved dimensional stability and stiffness. The glass fibers lock the polymer matrix in place, reducing thermal expansion, shrinkage, and creep, which is crucial for precision parts. -
Q: Is PPO GFN30F-780S suitable for outdoor applications?
A: While PPO has good hydrolytic stability, prolonged exposure to UV light can cause degradation. For outdoor use, UV-stabilized grades or protective coatings are recommended. This standard grade is best suited for indoor or protected environments. -
Q: Can this material be used in food contact applications?
A: The standard PPO GFN30F-780S is not specifically formulated or certified for food contact. For such applications, you would need to inquire about specialized, compliant grades. -
Q: How does it compare to other glass-filled plastics like nylon or PBT?
A: Compared to glass-filled nylon, PPO GFN30F-780S generally offers lower moisture absorption (better dimensional stability wet/dry), higher heat resistance, and better inherent flame retardancy. Versus glass-filled PBT, it typically has a higher continuous use temperature and better hydrolytic stability. -
Q: What are the typical processing conditions for injection molding?
A: A general starting point includes a melt temperature of 280-320°C and a mold temperature of 80-110°C. Due to its high glass content, it requires robust, wear-resistant molding equipment. Drying before processing is essential. -
Q: Is coloring available for this material?
A: Yes, coloring is possible. The natural color is an off-white. Custom colors can be produced through masterbatch addition during compounding or molding, subject to minimum order quantities. -
Q: What wall thicknesses are recommended for molding with this grade?
A: Recommended wall thickness typically ranges from 1.5 mm to 4.0 mm. Uniform wall design is important to minimize sink marks and internal stresses due to the high filler content. -
Q: Does Shanghai Yunshan Plasticizing provide material samples for testing?
A: Yes, we generally offer sample quantities for qualified customers to conduct their own molding trials and performance testing. Please contact our sales team to discuss your requirements.
