摘要:
Melamine-formaldehyde foams comprise from 80% to 98% by weight of an inorganic filling material, wherein the % by weight are based on the total weight of inorganic filling material plus melamine-formaldehyde precondensate used for foam production.
摘要:
Melamine/formaldehyde foams comprising from 0.01% to 45% by weight of a particulate filling material having an average particle diameter in the range from 5 μm to 3 mm, wherein the % by weight are based on the total weight of filling material plus melamine-formaldehyde precondensate used for foam production.
