Mechanical Properties of Polyvinyl-Acetate and Toluene Diisocyanate and Sulfonated Phenol-Formaldehyde Foam Composites

Abstract

Blend of polyvinyl acetate (PVA) and Toluene diisocyanate (TDI) were mixed with different percentages by weight of sulfonated phenol-formaldehyde (SPF) foam of prepared sulfonated phenol-formaldehyde resin. The measured mechanical properties such as the tensile modulus (E_t) values are (107, 43.7, 84.7, 424 and 165) MPa, for samples (1, 6, 7, 8 and 9). Tensile strength (?_M) before break are (0.923, 1.21, 5.56, 6.43 and 8.65) MPa, maximum force applied on the specimen number (9) is 355 N.  More information of the article can be found in the full paper.
