俄罗斯采购需求：耐火、聚合物添加剂

I'm interested in your product for a specific application in foamed rubbers and plastics, particularly for creating fire-resistant materials. Could you provide pricing details for orders of 25 kg and 100 kg? I'm looking to use this additive in various undercarriage equipment mats (2.5 * 3 meters) as well as for vibration and noise insulation in homes. Additionally, please let me know about any bulk order discounts and lead times for delivery. I plan to work on multiple projects that require different tonnage, so understanding your pricing structure and availability would be very helpful. Thank you!
