New Specialty Product Launch - We launched successfully a new specialty product in 2016. It is supplied in 15% to 35% aqueous solution of low molecular weight poly(styrene-maleic anhydride, SMA). The soluble nature SMA in alkaline solutions makes it suitable for various applications in paper sizing, binders, dispersants in pigments, inks and coatings, paraffin wax emulsions, adhesives and papers. The specific reactivity of SMA makes it a good agent for compatibilizing normally incompatible polymers or cross-linking. The SMA solutions are also used to improve performance of other systems such as Phenol-Formaldehyde, Urea-Formaldehyde, Melamine Formaldehyde systems, and exhibit good wet strength, excellence moisture resistance and strength after curing in applications such as glass/stonewool insulation, automotive insulation and glass fiber mats for non- woven applications such as vinyl flooring, ceiling tiles, roofing shingles.
