Superior Wear and Scratch Resistance<\/b><\/strong><\/h3>\n<p>In coatings and printing inks, hardness is directly linked to density. HDOPE waxes form substantially harder particles than LDOPE or standard paraffin. When these particles migrate to the surface (or are dispersed within the film), they act as &#8220;spacers&#8221; or slip agents that deflect physical stress.<\/p>\n<ul>\n<li><b><\/b><strong><b>Result: <\/b><\/strong>Better scratch resistance in wood coatings, coil coatings, and floor finishes.<\/li>\n<\/ul>\n<h3><strong><b>2. Higher Thermal Stability (Melting Point)<\/b><\/strong><\/h3>\n<p>HDOPE waxes typically soften and melt at higher temperatures (often &gt;130\u00b0C, depending on grade) compared to low-density variants.<\/p>\n<ul>\n<li><b><\/b><strong><b>Benefit: <\/b><\/strong>In plastics processing (like rigid PVC extrusion), the wax remains solid\/viscous longer in the extruder barrel, providing &#8220;delayed&#8221; external lubrication or metal release in later zones without degrading too early.<\/li>\n<\/ul>\n<h3><strong><b>3. Improved Mechanical Strength<\/b><\/strong><\/h3>\n<p>Because the polymer chains are linear and tightly packed, the wax itself is less brittle than low-molecular-weight by-products but harder than LDPE waxes.<\/p>\n<ul>\n<li><b><\/b><strong><b>Impact: <\/b><\/strong>In hot melt adhesives (HMA) or plastic composites, it modifies viscosity without sacrificing the structural integrity or softening point of the final product as much as softer waxes might.<\/li>\n<\/ul>\n<p><img decoding=\"async\" class=\"wp-image-1733 aligncenter\" src=\"https:\/\/www.rallychem.com\/wp-content\/uploads\/2026\/02\/111-300x200.jpeg\" alt=\"\" width=\"559\" height=\"372\" srcset=\"https:\/\/www.rallychem.com\/wp-content\/uploads\/2026\/02\/111-300x200.jpeg 300w, https:\/\/www.rallychem.com\/wp-content\/uploads\/2026\/02\/111-1024x683.jpeg 1024w, https:\/\/www.rallychem.com\/wp-content\/uploads\/2026\/02\/111-768x512.jpeg 768w, https:\/\/www.rallychem.com\/wp-content\/uploads\/2026\/02\/111-18x12.jpeg 18w, https:\/\/www.rallychem.com\/wp-content\/uploads\/2026\/02\/111.jpeg 1269w\" sizes=\"(max-width: 559px) 100vw, 559px\" \/><\/p>\n<h2><strong>Typical Applications<\/strong><\/h2>\n<p><img decoding=\"async\" class=\"wp-image-1740 aligncenter\" src=\"https:\/\/www.rallychem.com\/wp-content\/uploads\/2026\/02\/2-300x252.png\" alt=\"\" width=\"585\" height=\"491\" srcset=\"https:\/\/www.rallychem.com\/wp-content\/uploads\/2026\/02\/2-300x252.png 300w, https:\/\/www.rallychem.com\/wp-content\/uploads\/2026\/02\/2-768x645.png 768w, https:\/\/www.rallychem.com\/wp-content\/uploads\/2026\/02\/2-14x12.png 14w, https:\/\/www.rallychem.com\/wp-content\/uploads\/2026\/02\/2.png 863w\" sizes=\"(max-width: 585px) 100vw, 585px\" \/><\/p>\n<p>&nbsp;<\/p>\n<h2><strong>Choosing the Right High-Density Oxidized Polyethylene Wax<\/strong><\/h2>\n<p>Rallychem offers a comprehensive range of high-density <span style=\"color: #cc99ff;\"><a style=\"color: #cc99ff;\" href=\"https:\/\/www.rallychem.com\/ja\/%e8%a3%bd%e5%93%81\/%e9%85%b8%e5%8c%96%e3%83%9d%e3%83%aa%e3%82%a8%e3%83%81%e3%83%ac%e3%83%b3%e3%83%bb%e3%83%af%e3%83%83%e3%82%af%e3%82%b9\/\"><u><span style=\"color: #ff00ff;\">oxidized polyethylene wax grades<\/span><\/u><\/a><\/span>\u00a0with carefully controlled density, melting points, molecular weights, and oxidation levels.
