Why Choose Ryton R-7-120BL for Your Application?
In automotive pump systems, this PPS compound withstands continuous contact with engine oil, transmission fluid, and coolant without swelling or cracking. Its high rigidity ensures that pump impellers and housings maintain tight tolerances, reducing leakage and improving efficiency. For electronic components such as connectors, insulators, and coil bobbins, the material’s excellent dielectric properties and flame resistance provide reliable performance under electrical stress and thermal cycling.
Compared to standard PPS grades, the R-7-120BL offers enhanced flow for molding intricate designs with fine details. This means faster cycle times and lower reject rates for molders. Additionally, its black color eliminates the need for coloring during processing, saving time and cost.

Frequently Asked Questions (FAQ)
-
Q: Can Ryton R-7-120BL be used in food contact applications?
A: This grade is not specifically designed for food contact. Please consult our technical team for recommendations on FDA-compliant alternatives if needed. -
Q: What is the recommended drying condition before molding?
A: Pre-drying at 130–150°C for 3–4 hours is recommended to achieve optimal surface finish and avoid voids. Moisture content should be below 0.02% before processing. -
Q: Does this material offer UV resistance?
A: PPS inherently has limited UV stability. For outdoor applications, we recommend incorporating UV stabilizers or using a protective coating. Contact us for further guidance. -
Q: What is the typical shrinkage rate of R-7-120BL?
A: Mold shrinkage is approximately 0.3–0.5% in the flow direction and 0.6–1.0% across the flow. These values can vary depending on part geometry and processing conditions. -
Q: Is this compound suitable for metal insert molding?
A: Yes, due to its excellent flow and adhesion properties, it can be used for overmolding metal inserts. Proper preheating of inserts is recommended to reduce stress. -
Q: What is the maximum continuous service temperature?
A: Ryton R-7-120BL can be used continuously at temperatures up to 230°C (446°F) with short-term peaks up to 260°C (500°F). -
Q: Does Shanghai Yunshan provide material test reports?
A: Yes, we can provide a Certificate of Analysis (COA) with each shipment, including typical mechanical and thermal property data. Additional testing can be arranged upon request. -
Q: What are the typical lead times for large orders?
A: For stock items, delivery can be arranged within 5–7 working days. For custom packaging or large quantities, please allow 2–3 weeks. Contact our sales team for precise scheduling.
