Ceramic Fiber Blanket Process
Q:What is the maximum temperature your ceramic fiber blanket can withstand?
A:Our ceramic fiber blankets are rated for continuous use up to 1350°C (2462°F), depending on the specific grade (standard, high-purity, or zirconium-enhanced). They are designed for excellent thermal stability in extreme heat environments.
Q:Do your ceramic fiber blankets meet international safety and environmental standards?
A:Yes, all our ceramic fiber products are asbestos-free and fully comply with RoHS and REACH regulations. Safety and environmental compliance are core to our manufacturing process.
Q:What is the minimum order quantity (MOQ) for wholesale?
A;Our standard MOQ for wholesale orders is 100 square meters or 50 rolls, depending on thickness and density. However, sample orders and trial orders are welcome to support first-time buyers.
Q:Can you provide custom sizes, thicknesses, or packaging?
A:Absolutely. We offer OEM/ODM services, including customized dimensions, private-label packaging, and bulk pallet packing for export. Let us know your specific requirements.
Q:How is the product packaged for shipping?
A:Ceramic fiber blankets are rolled and packed in PE plastic bags, then loaded onto wooden pallets or cartons for better protection during international shipping. Customized packaging is available.
Q:What is your lead time for bulk orders?
A:Typical production lead time is:
3–7 days for regular sizes in stock
7–15 days for customized specifications
Shipping time depends on your location and chosen delivery method.
Q:What are your shipping options?
A:We support:
FOB, CIF, DDP (Sea Freight)
Air Freight
Express (DHL, FedEx, UPS) for urgent orders
Q:Can I request a sample before placing a bulk order?
A:Absolutely. We provide free standard samples (within size limits), with shipping costs covered by the buyer. For specialized samples, a small production fee may apply.
