Abstract
A process for forming an oil-sorbent composition of matter with bound combinations of styrene-butadiene-styrene (SBS) and ethylene propylene diene monomer (EPDM) utilizes a low-temperature extrusion process. The SBS, or both materials, may be in the form of multitudes of granules. In certain preferred embodiments, the combination is 10-30% by weight and the SBS is about 30% styrene and manufactured without talc. The composition of matter can be extruded into a solid, compliant body for use in a product for absorbing oil. The material can be extruded, in one preferred embodiment, into an extended cylinder body having an axial hole.
