Novel beater additives were prepared and the properties of the produced paper sheets were studied. From the results of non-isothermal thermogravimetric analysis of the prepared paper sheets, these additives can be used as a fire retardant. The results obtained also show that, this type of additives is suitable for producing magnetic paper, whereas its mass succeptibility value in some time is greater than that produced from adding magnetic metal oxides under the same conditions of preparation; while its semiconductor property is relatively higher than that obtained from adding metal oxides. In addition, using of such additives accept the sheets high strength properties, porous structure (air permeability value ∼ 800 ml/min.), and water resistance behavior. Its resistivity to water absorption is better than that obtained by chemically modification of the pulp to decrease its hydrophilicity, e.g., acetylation and grafting by hydrophobic monomer. Therefore, this type of paper sheets is suitable as a Nursery-plant boats. The biological evaluation of the produced paper sheets reveals that, the addition of novel additives gains the paper some anti-microbial action.
