Describes a deinking agent composition and a method for deinking wastepaper printed with electrostatic ink or mixtures thereof with wastepaper printed with impact ink in which a combination of nonionic surfactants are added to an alkaline slurry of paper fibers. The surfactants are a first nonionic surfactant represented by the formula:

Method for deinking electrostatic printed wastepaper using a combination

Describes flotation deinking of secondary fiber using a froth moderating agent, a composition of the froth moderating agent with flotation deinking chemicals, and reducing the amount of stickies in separated secondary fiber. The froth moderating agent is selected from the group consisting of:

Method for controlling froth and reducing stickies in the flotation

A deinking composition comprises a synergistic combination of a first nonionic surfactant material represented by the formula:

Deinking agent of nonionic surfactants

Describes a method for deinking wastepaper printed with electrostatic ink or mixtures thereof with wastepaper printed with impact ink in which a combination of nonionic surfactants are added to an alkaline slurry of the paper fibers. The surfactants are a first nonionic surfactant represented by the formula,

Process for deinking electrostatic printed paper using a combination of

Small particles of ammonium dihydrogen phosphate, diammonium hydrogen phosphate, or a mixture thereof provide a higher Limiting Oxygen Index ('LOI') to polyolefin compositions containing the small particles than do larger particles of the same substance. In many instances, improvement in one or more other properties, such as for example, processability, appearance, UL-94 rating, tensile strength, tensile modulus, and/or elongation at break is also obtained.
