Sabicintroduced a specialized portfolio of SABIC PP compounds for foam injection molding (FIM). New mineral-reinforced SABIC PPc F9005, PPc F9007 and PPc F9015 grades can help deliver excellent aesthetics for visible automotive interior parts with complex geometries, such as door panels and trim, seat and trunk cladding, A/B/C/D pillar covers and center consoles. Unlike standard FIM materials, which typically exhibit surface defects, the new advanced PP compounds feature uniformly high surface quality similar to solid injection molded parts. Compared to solid components, foamed parts made with SABIC PP compounds offer significant weight savings that can help cut emissions. According to a cradle-to-grave life cycle assessment study (pending third-party review), the advanced new materials can help OEMs lower carbon dioxide (CO2) emissions by as much as 15 percent.
SABIC总经理Abdullah Al-Otaibi表示：“汽车行业继续寻找可以提高能源效率和可持续性目标的新的体重策略。”“尽管泡沫注塑造型会产生理想的轻量级零件，但到目前为止，制造商一直被迫牺牲美学。我们在泡沫技术方面运用了广泛的专业知识来开发这些新化合物，以帮助解决表面质量的问题，并为泡沫零件开放新的应用程序机会。”
Solving the FIM Aesthetics Challenge
以前，FIM过程基本上仅限于不可疫苗的零件，从而限制了其在汽车应用中的实用性。泡沫表面美学的表现不佳：银条纹，漩涡状线和酒窝是常见的缺陷。用于泡沫的内部零件的SABIC PP化合物提供低质量的低光质感（粒度）表面，包括消除条纹和旋转。这些等级的滑石粉填充物充当核定器，可促进较细的气泡的产生，从而有助于表面外观一致。对于增强的美学，这些等级目前可在选定的汽车内部颜色中提供，并提供自定义着色。
优化体重优势
SABIC PP化合物的减轻重量结果取决于几个因素，包括使用的FIM技术类型。使用与注入模压零件相同的工具的短发模型可以减轻高达10％的重量。SABIC PPC 9007用于短发FIM和低影响应用。需要零件重新设计和新工具的核心成型，可以将重量降低多达30％。Sabic PPC 9005和PPC 9015级别均配制用于核心成型，并提供中等的刚度和影响。
The choice between the short-shot and core-back techniques, with their different tooling requirements, also helps to determine whether FIM with SABIC PP compounds is cost neutral or delivers cost savings. Additional cost savings are possible from cycle time reductions from flow improvements inherent in FIM.
Another consideration is the foaming process, which can use chemical or physical agents. The new SABIC PP compounds are good candidates for use with chemical blowing agents, which are typically preferred for visible foamed parts. These agents are introduced to the molding machine in the form of a masterbatch, along with the plastic pellets, and activate during the melt phase to release gases for foaming.
支持FIM应用程序开发和处理
SABIC充分支持其新的PP化合物组合，具有泡沫零件设计，开发和处理以及预测工程能力的广泛专业知识。例如，公司可以为每个等级选择适当的化学吹剂提供指导。SABIC的技术团队将与客户合作，以最低的零件重量来实现出色的美学。
为了推动聚合物泡沫的未来发展，Sabic在荷兰经营着一个泡沫创新中心。该中心配备了泡沫工艺功能以及分析设备，使公司能够开发新的泡沫解决方案和技术创新并与客户合作。
SABIC PP化合物在欧洲推出，即将在美洲和亚太地区提供可用性。
