| SABIC® LLDPE 318BJ is a butene linear low density polyethylene resin typically designed for easy processing and specially formulated for optimum thermal stability at high temperatures used in cast film extrusion. Cast film produced from SABIC® LLDPE 318BJ exhibit excellent optical properties, puncture resistance and tear strength. SABIC® LLDPE 318BJ is TNPP free. SABIC® LLDPE 318BJ is a butene Linear Low Density Polyethylene natural resin typically used for wire and cable applications. SABIC® LLDPE 318BJ contains a high level of antioxidants and does not contain any antiblock and/or slip agents. It exhibits good Environmental Stress Crack Resistance (ESCR). SABIC® LLDPE 318BJ is typically used as base resin for insulation and jacketing applications. Application Cast Film: SABIC® LLDPE 318BJ resin is typcially used for hand and pallet stretch wrap. Wire & Cable: Telecommunication and Power cable (LV, MV, HV) jacketing. Halogen-free flame retardant (HFFR) compounds. One-step or two-steps silane crosslinkable for cable insulation. This product is not intended for and must not be used in any pharmaceutical/medical applications.&& |
