FAQ
Frequently Asked Questions
Yes, it is commonly used in clothing, wigs, and plush toys. Its flame-resistant properties make it a safe choice for many applications.
Yes, but care instructions vary. It is generally quick-drying and colourfast, but high heat in washing or drying can damage it. Always check the manufacturer's label.
Its primary uses are in flame-resistant protective clothing (for industrial workers, firefighters), faux fur, wigs, upholstery for public spaces, and stuffed toys where fire safety is a concern.
While all are synthetic, modacrylic is chemically distinct, being a copolymer with a high halogen content (e.g., chlorine) which provides its inherent, non-melting flame resistance. Polyester and nylon are meltable thermoplastics.
