Frequently Asked Questions
Q1: What is the difference between Ryton R-7-120NA and other Ryton grades?
A1: R-7-120NA is a general-purpose injection molding grade with a balanced combination of mechanical strength, flame retardancy, and chemical resistance. It is supplied in natural color, whereas some grades come pre-colored or filled with glass fiber. It offers excellent processability for a wide range of parts.
Q2: Is this material suitable for injection molding?
A2: Yes, this grade is specifically designed for injection molding. Its melt flow characteristics allow easy filling of complex molds. Typical processing temperatures range from 300–340°C. We recommend drying the granules at 120–150°C for 3-4 hours before processing.
Q3: What flame retardant rating does this product have?
A3: Ryton R-7-120NA typically achieves a V-0 rating in the UL94 standard due to its inherent flame retardancy. However, we recommend reviewing the official technical datasheet for your specific lot to confirm. No halogenated flame retardants are used.
Q4: Can this PPS be used in food contact applications?
A4: PPS is generally not recommended for direct food contact unless specifically tested and certified. This grade is intended for industrial and automotive applications. For food-grade requirements, please consult our technical team for alternative options.
Q5: What is the shelf life of these granules?
A5: When stored in a cool, dry environment away from direct sunlight and moisture, the granules can maintain their properties for several years. Proper packaging (sealed bags) ensures no contamination. We recommend using within 24 months of receipt for optimal performance.
Q6: Do you provide samples before bulk order?
A6: Yes, we offer free samples of 1-5 kg for evaluation. Please contact us with your shipping details and application information. Samples are sent with a datasheet and certificate of analysis.
Q7: Is this PPS recyclable?
A7: PPS is a thermoplastic and can be mechanically recycled. However, due to its high melting point and chemical resistance, recycling requires proper sorting and processing. We recommend consulting a recycling specialist for your specific waste stream.
Q8: How does the natural color affect the final part appearance?
A8: Natural PPS has a light beige to amber hue. If a specific color is desired, you can add color masterbatch during processing. The material's compatibility with common pigments is good. We can also supply pre-colored versions on request.
