As Shanghai Yunshan Plasticizing Co., Ltd., a professional plastic raw material supplier based in Shanghai, China, we are proud to offer the Covestro ET3117 Polycarbonate Low Viscosity Fire Resistant Resin. This high-performance material is engineered to meet the demanding requirements of modern manufacturing, combining exceptional flame retardancy with superior processing ease. It represents a reliable solution for industries where safety and precision are paramount.
The Covestro ET3117 resin is designed to deliver outstanding value through its unique balance of properties. Its low viscosity significantly enhances flow characteristics during molding, allowing for the production of complex, thin-walled, and detailed parts with greater efficiency and reduced cycle times. Simultaneously, its inherent fire resistance provides a critical safety feature, helping products comply with stringent regulations without compromising on other mechanical or aesthetic qualities.
Key Features & Technical Specifications:
- Enhanced Fire Safety: The resin possesses inherent flame retardant properties, contributing to improved fire safety in final applications. This is crucial for components used in electrical enclosures, automotive interiors, and electronic devices.
- Superior Processability: The low viscosity nature ensures excellent melt flow, facilitating easier injection molding and extrusion. This leads to higher productivity, lower energy consumption during processing, and the ability to fill intricate mold geometries.
- Robust Mechanical Performance: Polycarbonate is known for its high impact strength, good dimensional stability, and resistance to heat and many chemicals. ET3117 maintains these core benefits while adding specialized fire resistance.
- Design Flexibility: The material supports the creation of transparent or tinted parts, offering aesthetic versatility alongside functional performance.
Detailed Advantages for Your Business:
| Advantage | Benefit to Client |
| Low Viscosity & Easy Flow | Reduces injection pressure, allows molding of complex designs, lowers production costs, minimizes defects like short shots. |

Frequently Asked Questions (FAQ)
Q1: What is the main difference between ET3117 and standard polycarbonate resin?
A: ET3117 is a specialized grade combining low viscosity for easier processing and inherent fire resistance. Standard PC may not have these specific properties unless modified with additives.
Q2: Can ET3117 be used for transparent applications?
A: Yes, polycarbonate is naturally transparent. ET3117 can be used to produce clear or lightly tinted parts while maintaining its flame retardant and low viscosity characteristics.
Q3: What fire safety rating does ET3117 typically achieve?
A: Covestro ET3117 is designed to help achieve ratings such as UL94 V-2 or better, depending on the part thickness and molding conditions. Specific certification data should be confirmed from the official technical datasheet.
Q4: Is this material suitable for injection molding thin-walled parts?
A: Absolutely. Its low viscosity is a key advantage for thin-wall molding, improving flow and fill in delicate mold sections, reducing the risk of incomplete filling.
Q5: Does it require any special handling or storage conditions?
A: It should be stored in a dry environment to prevent moisture absorption, which can affect processing. Standard procedures for handling thermoplastic resins apply.
Q6: Can colors be added to ET3117?
A: Yes, the resin can be compounded with colorants or masterbatches to produce a wide range of colored parts, subject to compatibility testing.
Q7: What are the typical processing temperatures for ET3117?
A: Recommended melt temperatures generally fall within the standard polycarbonate range, often between 280°C to 320°C. Exact parameters depend on the machine and part design.
Q8: Is ET3117 recyclable?
A: Like many thermoplastics, polycarbonate can be recycled. However, the presence of flame retardant additives may influence recycling protocols. End-of-life options should be evaluated based on local regulations.
