Polymer Modified Bitumens (PMB): Reactive polyolefins
Arkema Lotader® AX is a polyolefin terpolymers which are used for the formulation of PMB with superior properties in terms of resistance to rutting, abrasion and frettling, elastic return, decrease in temperature susceptibility especially in hot climates or imporant day/night excursion, dynamic properties (fatigue and thermal cracking, and extension of the life of asphalt pavements), chemical resistance.
Lotader® AX are easy to process, giving a low effect on viscosity, an outstanding bitumen storage stability and easiness to prepare in most common equipment (no need for high shear tank).
Furthermore, Lotader ® AX are efficient already at low loading – sensibly less than typical SBS or EVA loading – thus also yielding a cost advantage.
Beside standard roads where Lotader® AX will replace or integrate usual SBS or EVA modified bitumens, the end applications where the exceptional performance of Arkema Lotader® AX will be immediately seen range to hot-climate, day & night or seasonal temperature excursions, heavy traffic, bridges, roundabouts, bumps and gutters, speed humps, mountain roads, and all extreme weather or shear conditions.
The incredible chemical and solvent resistance of PMB modified with Lotader® AX make it also an elective Solution for roads subject to weather or chemical attack, fuel and gas stations, airports, etc.
Lotader® AX includes a wide range of grades which can be combined to adjust the softening point and other parameters.
Looking for an universal additive for your PMB, to be applied to all most extreme conditions?
Arkema Lotader® AX range is the perfect Solution for hot-climate, day & night temperature excursions, heavy city traffic or extra-urban traffic with continuous braking, bridges, roundabouts, bumps and gutters, speed humps, mountain roads, repairings, roads subject to weather or chemical attack (e.g. close to marine salt), fuel and gas stations, airports, and all extreme conditions.
