As Shanghai Yunshan Plasticizing Co., Ltd., a specialized supplier based in Shanghai, China, we are proud to offer the PC Covestro 2405 High Viscosity Granules. This premium polycarbonate material is engineered specifically for demanding extrusion processes, providing manufacturers with a reliable and high-performance solution for creating robust industrial components. Our direct supply ensures consistent quality and technical support, helping you achieve superior product outcomes and streamline your production workflow.
The Covestro 2405 grade stands out in the polycarbonate family due to its tailored high viscosity, which is a critical property for extrusion applications. This characteristic offers several distinct advantages during processing and in the final product.
Enhanced Melt Strength: The high viscosity provides excellent melt strength, crucial for maintaining shape and dimensional stability during extrusion, especially for complex profiles or large sheets. It reduces sagging and deformation in the die.
Improved Mechanical Properties: Products extruded from 2405 granules typically exhibit high impact resistance, good rigidity, and consistent tensile strength, making them suitable for technical applications.
Process Stability: The material offers good thermal stability and consistent flow behavior under extrusion conditions, contributing to smoother, more predictable processing and reduced waste.
Broad Processing Window: While designed for extrusion, its properties allow for adaptability within recommended processing parameters, offering some flexibility for manufacturers.

FAQ
Q1: What is the main advantage of using a high viscosity PC grade like 2405 for extrusion?
A: High viscosity provides greater melt strength during extrusion. This helps maintain the shape and dimensions of the extruded product, especially for complex or large cross-sections, reducing sagging and improving dimensional stability.
Q2: Can Covestro 2405 granules be used for injection molding as well?
A: This grade is specifically optimized for extrusion processing. While it might be processable on some injection molding machines, its high viscosity may not be ideal for typical injection molding cycles, and performance may differ from grades designed for that purpose.
Q3: What are the typical applications for extruded products made from this material?
A: Common applications include industrial profiles (for machinery, frames), sheets (for glazing, protective covers), and various technical parts that require good impact resistance, rigidity, and thermal stability.
Q4: Is the material available in colors other than natural?
A: The standard supply is in natural color. However, color customization may be available upon request or through compounding services. Please inquire for specific options.
Q5: What is the recommended melt temperature range for processing Covestro 2405?
A: The typical recommended melt temperature range for extrusion is around 280°C to 320°C. Exact settings may vary depending on the specific extruder and product design.
Q6: How is the material packaged and what are the standard quantities?
A: The granules are typically packaged in standard 25 kg bags. Larger quantities like palletized loads are available for bulk orders.
Q7: Does Shanghai Yunshan Plasticizing provide technical data sheets or processing guidelines?
A: Yes. As a supplier, we can provide relevant technical data sheets and offer general processing guidance based on the manufacturer's specifications and our experience.
Q8: Are there any special storage conditions required for these PC granules?
A: PC granules should be stored in a dry, cool environment away from direct sunlight and excessive moisture to maintain their properties before processing.
