As a specialized plastics supplier, Shanghai Wenqin Plastics Co., Ltd. is proud to offer our Chimei PMMA CM-207 Balanced Flow PMMA, a premium-grade material engineered specifically for high-performance optical applications. Established in 2020 and operating from Shanghai, we combine rigorous quality management with a focus on serving global markets, including North America, Europe, Asia, and beyond. Our CM-207 PMMA is designed to meet the exacting demands of manufacturers producing precision optical lenses and efficient light guides, providing a perfect balance of optical clarity, processability, and mechanical stability.

This product description details the exceptional features, technical specifications, and tangible benefits that the CM-207 grade brings to your production line.

Core Features & Technical Advantages:

Superior Optical Performance: The CM-207 grade exhibits exceptionally high light transmittance, minimal haze, and excellent clarity, which are fundamental for lenses and light guides where undistorted light transmission is critical.
Balanced Flow Characteristics: Specifically formulated for "balanced flow," this PMMA offers optimized melt viscosity during processing. This ensures:
- Excellent fill capability in complex, thin-walled mold designs common in optical parts.
- Reduced risk of flow marks or uneven filling, leading to more consistent part quality.
- Enhanced process stability, allowing for wider processing windows and potentially higher production yields.
High Mechanical Strength & Durability: PMMA is renowned for its rigidity and surface hardness. The CM-207 grade maintains these properties while offering good impact resistance (within the typical range for PMMA), making it suitable for components that require structural integrity alongside optical function.
Excellent Chemical & Weather Resistance: It possesses good resistance to many chemicals, UV radiation, and environmental weathering. This contributes to long-term stability and performance retention for outdoor lighting applications or lenses exposed to various conditions.
Good Thermal Stability: The material can withstand the temperatures encountered in typical injection molding processes and maintains its properties across a reasonable operating temperature range for finished optical parts.

Key Specifications & Parameters:

Property	Typical Value / Characteristic	Notes / Test Method
Light Transmittance	> 92%	High clarity for optical applications
Haze		Minimal light scattering
Melt Flow Rate (MFR)	Balanced flow grade (specific value available upon request)	Optimized for injection molding of optical parts
Tensile Strength	High (typical for PMMA)	Provides structural rigidity
Impact Strength	Moderate	Sufficient for many optical component designs
Heat Deflection Temperature	Good thermal resistance	Stable under processing and use temperatures
UV Resistance	Good	Suitable for outdoor applications

Benefits for Your Manufacturing Process:

Enhanced Product Quality: The high transparency and balanced flow directly contribute to producing lenses and light guides with superior optical performance and consistent dimensional accuracy.
Improved Processing Efficiency: The tailored flow properties can lead to easier molding, potentially shorter cycle times, and lower rejection rates due to filling issues.
Design Flexibility: The ability to fill complex molds reliably allows designers to pursue more innovative and efficient optical component geometries.
Material Reliability: PMMA is a well-established, predictable engineering plastic. Using a dedicated grade like CM-207 provides confidence in long-term material performance and consistency.
Supply Chain Support: Shanghai Wenqin Plastics provides reliable supply from major Chinese ports (Shanghai, Ningbo), supporting timely delivery to your global operations.

Shanghai Wenqin Plastics operates with a commitment to quality systems, supporting your need for reliable and traceable materials.

Frequently Asked Questions (FAQ):

Q: What exactly does "Balanced Flow" mean for the CM-207 PMMA?
A: "Balanced Flow" refers to a specific formulation of the PMMA polymer that provides an optimal melt viscosity during injection molding. It is neither too high (which could cause difficult filling) nor too low (which could lead to flash or weak welds). This balance aims to ensure smooth, consistent filling of molds, particularly beneficial for the often complex and precise molds used for optical lenses and light guides.
Q: Can CM-207 PMMA be used for extrusion processes as well as injection molding?
A: While its primary design and advantages are geared towards injection molding for discrete optical parts, PMMA grades can often be adapted for extrusion. For specific extrusion applications like continuous light guide profiles, it is recommended to consult with us to confirm suitability and any potential processing parameter adjustments.
Q: Is this material suitable for outdoor lighting applications?
A: Yes, PMMA generally offers good resistance to UV light and environmental weathering. The CM-207 grade inherits these properties, making it a viable candidate for outdoor light guides, lens covers, or signage where exposure to sunlight and weather is a factor. For extreme environments, additional testing or specific stabilization options might be discussed.
Q: What colors are available for the CM-207 grade?
A: The standard form is natural transparent PMMA, which provides the highest light transmittance. However, PMMA can be colored during processing. We can provide information on colorant compatibility or discuss the availability of pre-colored batches for specific project needs.
Q: How does CM-207 compare to other general-purpose or optical PMMA grades?
A: CM-207 is positioned as a grade that prioritizes a balance between optical properties (high transmittance) and processing ease (balanced flow). Some general-purpose grades may sacrifice clarity for easier flow or lower cost. Other high-end optical grades might focus solely on ultra-high clarity without optimizing flow. CM-207 aims to offer a best-in-class combination for applications where both top-tier optics and reliable molding are required.
Q: Are technical data sheets and samples available?
A: Absolutely. We provide comprehensive technical data sheets detailing physical, mechanical, optical, and thermal properties. We also offer sample quantities for customers to conduct their own process trials and quality evaluations before committing to larger orders.
Q: What is the typical lead time and packaging for orders?
A: Lead times depend on order quantity and current stock. Standard packaging is in sealed bags on pallets. Specific details regarding delivery schedules, packaging options, and shipment from our ports (Shanghai, Ningbo) will be provided upon inquiry and order confirmation.
Q: Does Shanghai Wenqin Plastics provide any technical support for processing this material?
A> As a supplier, we can provide basic recommended processing parameters (temperature, pressure, etc.) based on the material data sheet. For deep technical molding support, we recommend collaborating with your molding equipment provider or process engineers. We are happy to share our material expertise as part of the dialogue.
