Adflex X 101 H is a reactor TPO (thermoplastic polyolefin) manufactured using LyondellBasell' s proprietary Catalloy process technology. It exhibits a high softness and a low modulus, with a relatively high melt flow index. Adflex X 101 H is tailored to replace atactic polypropylene copolymers (APP) used for the modification of bitumen in roofing membranes. The percentage to be added can vary according to the quantity of the atactic polypropylene used in combination with Adflex X 101 H and the requested cold bending temperature of the end product. Due to the high molecular weight of Adflex X 101 H, high blend viscosity and good penetration values are obtained. Its structure is tailored to obtain easy dispersion and phase inversion in the bitumen blend. Adflex X101H is also used in other industrial applications where high flexibility and the capability of accepting high filler loading levels are required. The grade is available in natural pellet form.
