I'm looking to purchase some Cordierite honeycomb monoliths with a specific density range. We need a quantity of approximately 45-46 pieces for an upcoming project. It's important for us to ensure they meet our performance requirements, so any details on their specifications, quality standards, and availability would be appreciated. Additionally, I'd love to know the lead time for production and delivery, as well as your pricing structure, including any bulk discounts. Please provide any technical datasheets or certifications that could help us evaluate the product better. Looking forward to your prompt response!
