As a specialized manufacturer of engineering plastics, Shanghai Wenqin Plastics Co., Ltd. proudly introduces our 223R-111 Polycarbonate Granules. Engineered specifically to address the critical challenge of warpage in precision molding applications, this grade represents our commitment to providing molders with a material solution that enhances part accuracy, reduces post-processing, and improves overall production efficiency. By focusing on stability and dimensional consistency, we help our clients in various global markets achieve higher quality standards in their molded components.
Our 223R-111 PC Granules are formulated to deliver exceptional performance where tight tolerances and complex geometries are required. The core value lies in its low warpage characteristic, which minimizes distortion during and after the molding process. This leads to parts that meet design specifications more reliably, reducing scrap rates and assembly issues. Below, we detail the specific features, technical specifications, and advantages that make this product a preferred choice for demanding applications.
Product Characteristics & Advantages:
- Enhanced Dimensional Stability: The formulation significantly reduces internal stresses that cause warping, ensuring molded parts maintain their intended shape and dimensions.
- High Precision Moldability: Excellent flow properties allow for filling thin walls and intricate details, crucial for components like connectors, lenses, and automotive parts.
- Consistent Mechanical Properties: Maintains polycarbonate's inherent high impact strength, good heat resistance, and transparency (in natural grade), alongside improved stability.
- Process Optimization: Lower warpage can lead to reduced cooling times, less reliance on complex mold designs for compensation, and smoother production cycles.
- Broad Application Suitability: Ideal for sectors where precision is paramount, including electronics, automotive, medical devices, and optical components.

Frequently Asked Questions (FAQ):
-
What exactly does "low warpage" mean for this PC granule?
"Low warpage" refers to the material's reduced tendency to deform or change shape unevenly after being injection molded and cooled. This is crucial for parts requiring tight dimensional tolerances. -
Can I use this grade for transparent parts?
The standard natural color grade offers good transparency typical of polycarbonate. For specific optical clarity requirements, please consult with us as formulations can be adjusted. -
Does the low warpage feature affect other properties like impact strength?
No, the formulation aims to enhance dimensional stability while preserving the core advantageous properties of polycarbonate, including its high impact resistance. -
What are the typical injection molding settings recommended for this material?
General PC processing parameters apply, such as moderate to high melt temperatures. Specific machine settings (temperature, pressure, cycle time) can be provided based on your part geometry and mold design. -
Is this material suitable for medical or food-contact applications?
Our standard 223R-111 grade is formulated for general precision engineering applications. For medical or food-contact use, specific compliance requirements must be evaluated; we can discuss custom formulations if needed. -
How does the packaging work, and what are the minimum order quantities?
Standard packaging is 25kg sealed bags to ensure cleanliness and moisture protection. Minimum order quantities are flexible and depend on your needs; we encourage you to inquire for details. -
Can you provide material samples for testing?
Yes, we typically can provide samples for evaluation in your molding process. Please contact us with your request and application details. -
What is the lead time for orders, and from which ports do you ship?
Lead times vary based on order size and production schedule. We primarily ship from Shanghai and Ningbo ports, facilitating logistics to our main markets worldwide.
