Frequently Asked Questions
❓What is RPZH-06 and what is it used for?
RPZH-06 is a halogen-free flame retardant masterbatch designed specifically for PP fiber and nonwoven fabrics. It is used to impart flame retardancy to spunbond, SMS, and other PP-based nonwoven materials used in protective, industrial, building, and transportation applications.
❓What flame retardant standards can RPZH-06 help achieve?
When added at a dosage of 5%, RPZH-06 can help PP nonwoven fabrics achieve an Oxygen Index higher than 28, pass the USA UL94-V-0 standard, and meet the UK BS5852-Part1:1979 test requirements.
❓What is the recommended dosage for RPZH-06?
The recommended add dosage is 3–8%, depending on the specific flame retardant performance required and the fabric structure. A dosage of 3–5% is typical for standard applications, while higher dosages may be used for more stringent requirements.
❓Will RPZH-06 affect the physical properties of the nonwoven fabric?
RPZH-06 is formulated to have minimal impact on fabric properties. It maintains tensile strength, hand feel, and appearance, and does not significantly influence fabric uniformity or bonding during production.
❓Is RPZH-06 compatible with existing nonwoven production lines?
Yes. RPZH-06 is compatible with mainstream nonwoven production lines including high-speed spunbond and SMS systems. It ensures stable extrusion and filament formation, making it suitable for continuous production without disrupting normal processing.
❓Does RPZH-06 contain halogens or produce toxic smoke?
No. RPZH-06 is a halogen-free flame retardant system. During combustion, it produces low smoke and low toxicity, making it a safer and more environmentally friendly choice compared to traditional halogenated flame retardants.
