Crosslinkable SBCs resist heat & oil swell.Septon Co. of America, Pasadena, Texas, has come out with the Septon V9000 series of hydrogenated styrenic block copolymers with crosslinkable hard blocks. They are curable cur·a·ble adj. Capable of being cured or healed. with peroxide peroxide (pərŏk`sīd), chemical compound containing two oxygen atoms, each of which is bonded to the other and to a radical or some element other than oxygen; e.g. , electron beam A stream of electrons, or electricity, that is directed towards a receiving object. See electron beam imaging and electron beam lithography. , or uv. These products reportedly offer better oil and heat resistance than typical SBCs or olefinic TPVs for use in automotive underhood and interior applications. While standard compression-set tests of Septon V9000 yield results equivalent to standard olefinic TPVs, long-term Long-term Three or more years. In the context of accounting, more than 1 year. long-term 1. Of or relating to a gain or loss in the value of a security that has been held over a specific length of time. Compare short-term. (1000-hr) compression set is said to be much better for the new SBCs. The materials are also said to be easy to process by injection and extrusion. Wire and cable grades are in development.
