    摘要: This invention relates to a process for producing phenolformaldehyde foams, also known as phenolic foams, of improved properties. The inventive feature resides in using a controlled combination of the various components in the curing reaction mixture and in controlling the temperature within the mass of the curing mixture. The process is applicable to production of block or laminated foams. Phenolic foams find increasing use in building applications where their thermal insulation and fire resistant properties are of value.

    摘要: The present invention relates to a process and an apparatus for producing phenolic foam laminates with improved surface appearance. The process involves applying pressure on the foam forming mixture through one of its facings by a flexible member. The member is sufficiently flexible to allow continual rise of the foam but also smoothes out any uneven rise under the applied pressure thereby producing a laminate which has a surface immediately below the facing substantially free of any voids, craters or wrinkles.
