Suzhou Yifuhui New Material Co., Ltd. is pleased to introduce Makrolon 2807 PC Pellets, a high-performance polycarbonate material specially engineered to maintain excellent impact strength even under subzero environments. This grade is ideal for applications where cold-temperature toughness is critical, such as automotive components, outdoor equipment, and electronic housings exposed to freezing conditions. With our reliable global supply chain and export experience exceeding US$10 million – US$50 million annually, we ensure consistent quality and competitive pricing for bulk orders.
Makrolon 2807 is a general-purpose injection molding grade from the famous Makrolon® series, offering a well-balanced combination of impact resistance, dimensional stability, and flowability. Unlike standard polycarbonates that become brittle at low temperatures, this material retains its ductility and toughness down to -40°C (-40°F), making it a trusted choice for demanding applications in cold climates. Below we detail the key characteristics and benefits.
Key Features & Technical Specifications
- Exceptional Low-Temperature Impact Strength: Maintains ductile behavior at subzero temperatures, reducing risk of fracture in cold environments.
- High Transparency & Clarity: Natural grade offers light transmission up to 89%, suitable for transparent components.
- Excellent Dimensional Stability: Low moisture absorption and minimal shrinkage ensure precision parts.
- Good Flowability for Injection Molding: Easy processing with wide processing window (melt temperature 280–320°C).
- UL94 V-2 Flame Rating Available: Meets standard safety requirements for electronic applications (upon request).
- Available in Custom Colors: Color masterbatch can be added to meet specific requirements.
| Property | Value | Unit |
|---|---|---|
| Density | 1.20 | g/cm³ |
| Melt Flow Rate (MFR) at 300°C/1.2 kg | 10 | g/10 min |
| Impact Strength (Charpy, notched) at 23°C | 65 | kJ/m² |
| Impact Strength (Charpy, notched) at -30°C | 50 | kJ/m² |
| Tensile Modulus | 2400 | MPa |
| Vicat Softening Temperature (B50) | 148 | °C |
In addition to the above properties, Makrolon 2807 offers excellent UV resistance (when formulated with stabilizers) and can be used in outdoor applications with proper protection. The material also exhibits good chemical resistance to many dilute acids and oils, though prolonged exposure to strong bases or solvents should be avoided.
Benefits for Your Application
- Reliability in Harsh Winters: Products made from this grade will not become brittle in freezing temperatures, reducing warranty claims.
- Lightweight & Design Flexibility: Enables thin-wall injection molding while maintaining strength, reducing material costs.
- Global Compliance: Meets RoHS, REACH, and other international standards (certification documents available upon request).
- Cost-Effective Supply: As a professional trading partner with annual exports of US$10–50 million, we offer competitive pricing and stable stock.

Frequently Asked Questions (FAQ)
1. Does Makrolon 2807 really maintain impact strength at subzero temperatures?
Yes. Makrolon 2807 is specifically formulated to retain ductility and impact resistance down to -40°C. Notched Charpy impact tests show values above 50 kJ/m² at -30°C, which is significantly higher than standard polycarbonates.
2. What processing conditions are recommended for injection molding?
Typical melt temperature is 280–320°C, mold temperature 80–120°C. Drying is required at 120°C for 2–4 hours to ensure moisture below 0.02%. Please refer to the technical datasheet for detailed guidelines.
3. Is this material suitable for food contact applications?
Unmodified Makrolon 2807 may comply with certain food contact regulations, but specific certification depends on your country. We can provide relevant documents upon request to help you evaluate compliance.
4. Can I get custom colors or UV-stabilized versions?
Yes. We can supply color masterbatches or add UV stabilizers as per your requirements. Minimum order quantities may apply for custom formulations.
5. What is the typical lead time for large orders?
For standard transparent/natural pellets, lead time is about 7–15 days after order confirmation, depending on quantity. For custom colors, please allow additional 10–20 days.
6. Do you provide free samples for testing?
Yes. Small samples (1–5 kg) are available free of charge, but the buyer pays shipping costs. Contact our sales team to request samples.
7. What certifications do you have?
We can provide Material Safety Data Sheets (MSDS), technical datasheets, and compliance declarations (RoHS, REACH). Third-party test reports are available upon request. Note that specific product certifications (e.g., UL, FDA) should be verified with the end-use application.
8. How do you ensure product quality and consistency?
We work with trusted suppliers and conduct incoming quality checks on each batch, including MFR and impact tests. Regular audits ensure traceability. We also offer batch certificates with every shipment.
Conclusion: With its proven performance under extreme cold, excellent processing characteristics, and our reliable supply network, Makrolon 2807 PC Pellets are the ideal choice for manufacturers seeking durability in freezing environments.
