Inquiry (采购产品): Unground balls We will need between 500 and 1000 pounds of neoprene solid 1 inch diameter or 1.5 inch diameter balls in about 6 months from now. These should be as molded and not polished or ground. Please advise approximate cost and availability. If you can not supply, do you have a recommendation? By the way, what is the void volume of balls in a drum. We think it is about 35% but are not sure for calculating the amount needed based on neoprene density. **** Hidden Message ***** Jan Kruyer Box 138 Thorsby, AB T0C 2P0 CAN Company: Oleophilic Sieve Development Of Canada Title: Engineer Phone: 780-789-4051 E-mail: janman1@persona.ca **** Hidden Message ***** janman1@persona.ca
