For over 40 years, NuCera polymers have provided the full range of advantages required to produce the world\u2019s finest EPS industry. <\/p>\n\n<p><strong>Applications<\/strong><\/p>\n\n<ul class=\"wp-block-list\">\n<li>Improved density potential<\/li>\n\n\n\n<li>Faster prepuff maturation<\/li>\n\n\n\n<li>Better foam strength at the required density<\/li>\n\n\n\n<li>Faster mold cooling time<\/li>\n\n\n\n<li>Improved molding fusion<\/li>\n<\/ul>\n\n<p>NuCera POLYWAX\u2122 polyethylenes are fully saturated homopolymers of ethylene that exhibit a high degree of linearity and crystallinity. These synthetic waxes have narrow molecular weight distributions with a typical polydisperity (Mw\/Mn) of 1.08. In application, POLYWAX polyethylenes exhibit sharp melting point, fast recrystallization, low melt viscosity, excellent heat stability and resistance to chemical attack.  <\/p>\n\n<p>When used in EPS production, POLYWAX polyethylenes promote the formation of small, uniformly sized cells, providing better surface finish and lower density of the final product. During the forming process, POLYWAX polyethylenes also perform as a mold release agent, reducing waste and improving cycle times <\/p>\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>The unique physical properties of POLYWAX polyethylenes\u2026<\/th><th>\u2026promote outstanding EPS products with excellent cell structure<\/th><\/tr><\/thead><tbody><tr><td>Narrow molecular weight distribution<\/td><td>Improved cell uniformity \u2013 Narrower cell size distribution- Smaller cell size at the required concentration<\/td><\/tr><tr><td>High crystallinity<\/td><td>More blowing agent at the nucleating site \u2013 Consistent cell size<\/td><\/tr><\/tbody><\/table><\/figure>\n\n<p><strong>What makes POLYWAX polyethylenes The Most Effective Nucleating Agents?<\/strong><\/p>\n\n<ul class=\"wp-block-list\">\n<li>Dissolve completely prior to significant polymerization<\/li>\n\n\n\n<li>Provide a critically sized nucleation site in the polystyrene matrix<\/li>\n\n\n\n<li>Serve as a gathering site for blowing agent<\/li>\n\n\n\n<li>Remain solid at expansion temperatures<\/li>\n<\/ul>\n\n<p><strong>Effect on EPS Cell Structure<\/strong><\/p>\n\n<p>The photos below are of EPS beads, taken with a Scanning Electron Microscope (SEM), at 50X magnification.
