I'm currently looking for black flame retardant ropes made from polyester, specifically in two sizes: 2mm and 0.4mm. It's crucial for my project that the ropes meet safety standards and have reliable flame resistance. If your factory can provide these specifications, I'd love to know more about the available options, including any relevant certifications you might have. Additionally, could you please provide details on pricing, minimum order quantities, and lead times for shipment? If there are samples available, I'd be interested in seeing them before making a larger commitment. I appreciate your assistance and look forward to your reply with the requested information.
