ENorsorex® APX is a high molecular weight, pure hydrocarbon-based polynorbornene polymer (C7H10)x, synthesized from a non-toxic and non-mutagenic monomer (2-norbornene). The dry, non-abrasive powder has a strong affinity to various hydrocarbons and absorbs these by a solidification process using Van der Waals forces. This process depends on the nature of the hydrocarbon, oil/polymer ratio and temperature used.
