Through physical micro\u001espike effects that rupture the road water film and chemical Al\u001eO\u001eSi covalent bonds that integrate the ultra\u001ehard inorganic phase into the rubber network, it simultaneously breaks the classic &#8220;magic triangle&#8221; trade\u001eoff among wet grip, rolling resistance and wear resistance in tire formulations.

Over the past three decades, the introduction of silica\/silane coupling agent systems has partially alleviated this contradiction, but the industry is still searching for new material pathways that can achieve breakthroughs in all three dimensions simultaneously.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">NSA04 was developed precisely to address this industry pain point:&nbsp;<a href=\"https:\/\/sanezenrubber.com\/ru\/product\/\"><strong><u><strong>not relying on the traditional single\u001eminded approach of &#8220;increasing hysteresis loss to gain wet grip&#8221;, but redefining the filler\u001erubber interfacial relationship at the molecular level through both physical and chemical mechanisms<\/strong><\/u><\/strong><\/a>.

DMA data show: 0\u2103&nbsp;tan\u03b4 increases by 8.3%\u001e10.3% (wet grip improvement), while 60\u2103&nbsp;tan\u03b4 decreases by 10.4%\u001e11.6% (rolling resistance reduction).

Its broad particle size distribution (D10 = 0.104 \u03bcm, D90 = 18.137 \u03bcm) balances nano\u001escale surface activity with micron\u001escale processability \u2013 an engineering\u001eoptimised design.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Misconception 3: The more functional filler added, the better.<\/strong><br>The recommended dosage for NSA04 is 10\u001e30 phr.

High tan\u03b4 near 0\u2103&nbsp;means good wet grip, but high tan\u03b4 near 60\u2103&nbsp;means high rolling resistance. Traditional fillers (carbon black, silica) mainly improve performance by enhancing rubber viscoelasticity, thus inevitably falling into the &#8220;trade\u001eoff&#8221; trap.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Root Cause 2: Water\u001efilm lubrication effect on wet roads<\/strong><br>The loss of grip on wet roads is essentially the replacement of direct rubber\u001eroad contact by a water film, changing friction from &#8220;solid\u001esolid&#8221; boundary friction to &#8220;solid\u001efluid&#8221; lubricated friction. Traditional solutions rely on rubber micro\u001emorphology and formulation design to &#8220;drain&#8221; water, but with limited effectiveness.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Root Cause 3: Stress transfer efficiency at the filler\u001erubber interface<\/strong><br>Wear resistance depends on filler dispersion and interfacial bonding strength. Poorly dispersed filler agglomerates become stress concentration points, inducing micro\u001ecracks under dynamic loading; weakly bonded fillers debond under repeated stress, accelerating wear.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">NSA04\u2019s technical value lies in&nbsp;<a href=\"https:\/\/sanezenrubber.com\/ru\/product\/\"><strong><u><strong>addressing all three root causes simultaneously<\/strong><\/u><\/strong><\/a>: physically rupturing the water film (not relying on viscoelasticity), chemically optimising the filler\u001erubber interface via Al\u001eO\u001eSi bonds (reducing internal friction), and reinforcing stress transfer through the rigid inorganic phase (improving wear resistance).
