cum processing aid. Its molecular weight (IV-9.5 -10.5) is optimized for achieving low density and efficient process- ability of cellular vinyl products by increasing inter-particle friction by breakdown of vinyl grain. It has multiple benefits: (1) reduced foam density, (2) improved surface finish and (3) cell uniformity. Due to its superior melt strength, it is ideal for foamed profiles, core pipes by generating outstanding profile shape with improved filling. It allows process optimization such as increased line speeds.

layered co-polymeric processing aid with an unmatched molecular weight index ( IV 11 – 12 ) achieved due to very low temp curing to lengthen the polymer chains. Specially designed for thicker cross sections, to ensure that deep core area of any cross section has no flaws and cell structure is uniform. The resultant product has: (1) much lower density (2) excellent surface quality, (3) cell uniformity, (4) improved impact strength while maintaining melt homogeneity. It not only increases inter-particle friction for accelerated fusion process, but also traps evolving gas and prevents bubbles from coalescing.
