As a dedicated plastics distributor and solution provider, Shanghai Wenqin Plastics is proud to offer the D151-701 SABIC Polycarbonate Molding Compound, a premium engineering material engineered specifically for long-term performance in challenging environments. We leverage our established supply chain and technical understanding to bring this high-performance resin to manufacturers across the globe, helping them build more reliable and durable products. This hydrolysis-resistant grade is a testament to advanced polymer technology, addressing one of the most common failure modes for polycarbonate in humid or wet applications. For businesses seeking to enhance product lifespan and reduce warranty claims, this material presents a significant upgrade over standard PC compounds.
This specialized molding compound is designed to withstand the degrading effects of prolonged exposure to moisture and heat, a condition known as hydrolysis. Standard polycarbonate, while tough and impact-resistant, can experience molecular weight reduction and a consequent loss of mechanical properties when exposed to hot water or high-humidity environments over time. The D151-701 grade incorporates advanced stabilization packages to significantly slow this process, ensuring that critical properties like impact strength, tensile strength, and dimensional stability are maintained for extended periods.
Core Technical Advantages and Specifications:
- Superior Hydrolytic Stability: The formulation is optimized to resist the chemical breakdown caused by water molecules, making it ideal for components that are in constant contact with water, steam, or high atmospheric humidity.
- Retained Mechanical Properties: Even after prolonged aging in hot/wet conditions, it maintains a high percentage of its original impact resistance, stiffness, and strength compared to conventional PC grades.
- Excellent Processability: Despite its specialized additives, it retains the good melt flow characteristics necessary for efficient injection molding, allowing for the production of complex, thin-walled parts.
- High Clarity and Gloss: In its natural form, it offers the excellent optical clarity typical of polycarbonate, suitable for applications where transparency is required alongside environmental resistance.
- Wide Service Temperature Range: It combines good heat resistance with improved performance at elevated temperatures in the presence of moisture.
Typical Property Profile (Representative Values):
| Property | Test Method | Typical Value | Unit |
|---|---|---|---|
| Melt Flow Rate (300°C/1.2kg) | ISO 1133 | 10 - 15 | g/10 min |
| Tensile Strength at Yield | ISO 527 | Approx. 60 | MPa |
| Flexural Modulus | ISO 178 | Approx. 2300 | MPa |
| Notched Izod Impact (23°C) | ISO 180 | Approx. 70 | kJ/m² |
| Heat Deflection Temp (1.8 MPa) | ISO 75 | Approx. 125 | °C |
| Density | ISO 1183 | Approx. 1.20 | g/cm³ |
Benefits for Your Business and End-Products:
- Extended Product Lifespan: Components made from D151-701 last longer in real-world conditions, reducing failure rates and enhancing brand reputation for quality.
- Reduced Total Cost of Ownership: While the material may have a premium, the reduction in returns, repairs, and replacements over the product's life can lead to significant cost savings.
- Design Freedom for Demanding Applications: Enables the use of polycarbonate's excellent combination of clarity, impact resistance, and heat resistance in applications previously considered too harsh.
- Reliability in Critical Parts: Ideal for safety-critical components or parts where failure would be highly disruptive or costly.
Target Applications Include:
- Water Management: Components for water filters, humidifiers, flow meters, and valve housings.
- Consumer Appliances: Steam-related parts in coffee makers, kettles, irons, and dishwashers.
- Electrical & Enclosures: Connectors, sockets, and enclosures used in humid outdoor or industrial settings.
- Automotive: Under-hood components, fluid reservoirs, and lighting parts exposed to weather and hot wash cycles.
- Medical & Laboratory: Housings for equipment that undergoes frequent autoclaving or steam sterilization.

Frequently Asked Questions (FAQ)
Q1: How does "hydrolysis resistance" actually improve the performance of this polycarbonate compared to a standard grade?
A1: Hydrolysis resistance refers to the material's enhanced ability to withstand chemical degradation when exposed to water, especially at elevated temperatures. Standard PC can experience chain scission (breaking of polymer chains) over time in hot/wet environments, leading to embrittlement and loss of strength. This grade contains additives that stabilize the polymer against this attack, significantly prolonging the time it retains its key mechanical properties like impact and tensile strength.
Q2: Can this material be colored, or is it only available in natural (clear) form?
A2: Yes, it can be colored. While the base resin is typically supplied in natural pellets suitable for transparency, it is fully compatible with a wide range of colorants and masterbatches for injection molding. Coloring may be done by the processor or can be discussed as a custom service.
Q3: Are there any special drying or processing conditions required for D151-701?
A3: Like all polycarbonates, it is hygroscopic and must be thoroughly dried before processing to prevent defects and property loss. Recommended drying conditions are typically 120°C for 3-4 hours. Otherwise, its processing parameters are similar to other injection molding PC grades, though always consult the specific technical datasheet for optimal settings.
Q4: What is the typical lead time for ordering this material?
A4: Lead times depend on order quantity and current stock levels. As an established distributor with access to SABIC's production, we generally offer competitive lead times. Specific timelines can be provided upon request with your quantity and destination port details.
Q5: Is this material suitable for applications involving contact with food or drinking water?
A5: The base SABIC polycarbonate resins often have grades compliant with various regional food contact regulations. However, compliance for the specific D151-701 grade must be verified for your intended application and region. We can provide available regulatory documentation upon request to support your evaluation.
Q6: Can you provide material samples for testing before we place a bulk order?
A6: Yes, we typically can arrange for sample quantities to be sent for your evaluation and testing purposes. This allows you to verify processability and performance in your specific application before committing to a larger purchase.
Q7: Does this grade have any flame retardant properties?
A7: The D151-701 is primarily formulated for hydrolysis resistance. It is not inherently flame-retardant. If flame retardancy (FR) is a requirement, SABIC offers other PC grades that combine FR properties with various performance features, and we can help identify a suitable alternative.
Q8: What kind of technical support do you offer with this product?
A8: Our support includes providing standard technical datasheets, safety data sheets (SDS), and general processing guidelines. For in-depth application engineering or troubleshooting, we can leverage the manufacturer's technical resources to assist our customers in achieving optimal results with the material.
