SABIC® LLDPE 218BJ是一种具有添加剂包装的丁烯线性低密度聚乙烯树脂,通常设计用于更广泛的食品应用(无TNPP)。良好的热稳定性允许在关键的挤压加工条件下使用树脂。与低mfr-lldpe树脂相比,从SABIC® LLDPE 218BJ生产的薄膜具有更好的拉伸性能。SABIC® LLDPE 218BJ是一种线性低密度聚乙烯天然树脂,通常用于电线和电缆应用。SABIC® LLDPE 218BJ含有高水平的抗氧化剂,不含任何抗阻剂和/或抗滑剂。具有良好的抗环境应力开裂性能。应添加足够的铜抑制剂,以满足特定的老化要求。对于护套应用,需要添加炭黑或紫外线稳定剂。应用吹塑膜:SABIC® LLDPE 218BJ通常用于食品应用(层压膜、阻挡膜),但也可用于工业包装,并作为与其他SABIC PE树脂在吹塑和铸膜应用中的混合伙伴。SABIC® LLDPE 218BJ通常用于食品应用(层压膜、阻挡膜)和托盘手包。色母粒复合:适用于薄膜和吹塑应用中的添加剂色母粒(如滑模剂、防雾剂、防静电剂、热稳定剂)。电线电缆挤出:电信和电力电缆(低压、中压、高压)护套。无卤阻燃(HFFR)化合物。一步或两步硅烷交联电缆绝缘。本产品不适用于任何医药/医疗应用,也不得用于任何医药/医疗应用。 SABIC® LLDPE 218BJ is a butene linear low density polyethylene resin with an additive package typically designed for a broader range of food applications (TNPP free). The good thermal stability allows to use the resin in critical extrusion processing conditions. Films produced from SABIC® LLDPE 218BJ have better draw-down ability compared to lower MFR LLDPE resins. SABIC® LLDPE 218BJ is a Linear Low Density Polyethylene natural resin typically used for wire and cable applications. SABIC® LLDPE 218BJ contains a high level of antioxidants and does not contain any antiblock and/or slip agents. It also exhibits good Environmental Stress Crack Resistance (ESCR). Sufficient Cu-inhibitor should be added to meet specific ageing requirements. For jacketing applications, addition of Carbon Black or UV stabilizer is required. Applications Blown Film: SABIC® LLDPE 218BJ is typically used for food applications (lamination film, barrier film) but can also be used in industrial packaging and as blending partner with other SABIC® PE resins in both blown and cast film applications. SABIC® LLDPE 218BJ is typically used for food applications (lamination film, barrier film) and pallet hand wrap. Masterbatch Compounding: It is suitable for additive masterbatches (eg. slip agents, anti fog agents, anti static agents, thermal stabilizers) in film and blow moulding applications. Wire & Cable Extrusion: 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. |
