上海,2026年10月8日——德国特殊化学品公司朗盛推出全新阻燃产品平台 Purventis®,面向保温材料解决方案领域。该平台首款商用产品 Purventis® Core 为反应型无卤磷系阻燃剂,适用于硬质聚氨酯(PU)与聚异氰脲酸酯(PIR)保温泡沫。当前,多元醇配方研发商、聚氨酯组合料厂商、保温板材及喷涂泡沫生产商,愈发期望 PU/PIR 保温体系可同时兼顾防火性能、低排放特性、加工实用性与长期法规适配能力,Purventis® Core 正是为响应这一市场需求研发而成。

硬质聚氨酯(PU)与聚异氰脲酸酯(PIR)泡沫广泛用于节能建筑保温,应用场景包括建筑板材、屋面墙体保温以及闭孔喷涂泡沫。随着全球法规体系不断发展,保温材料生产商亟需能够兼顾未来合规要求与产品技术指标的阻燃技术。在此背景下,PU/PIR 行业迎来一款极具竞争力的全新方案,可替代磷酸三 (1 - 氯 - 2 - 丙基) 酯(TCPP)、磷酸三乙酯(TEP)等传统添加型阻燃剂。

反应型化学技术,应对保温领域全新需求

Purventis® Core 基于朗盛原有 Levagard® 2100 技术平台开发,是一款低粘度、无卤、非芳香族、不含磷酸三苯酯(TPP)及苯酚的反应型磷系阻燃剂。不同于其他添加型阻燃剂,该产品能够化学键合进入聚氨酯基体。依托这一特性,生产商在开展配方调整、产品重新认证及技术规格变更时,仍可维持硬质 PU/PIR 保温材料所需的全部性能。

朗盛聚合物添加剂业务部应用开发负责人 Heiko Tebbe 表示:“依托 Purventis®,我们为保温材料市场打造定位清晰的产品平台。Purventis® 基于客户熟知的成熟技术研发,直击 PU 与 PIR 保温领域当下备受关注的核心课题:法规适配能力、低排放特性、资料备案以及稳定可靠的泡沫性能。”

测试数据印证更低排放及更少添加量

测试结果表明,Purventis® Core 不会提升总挥发性有机化合物(VOC)排放,印证该产品已键合至聚合物体系。相较于 TCPP 与 TEP,该技术拥有更高的阻燃效率。这一点对生产商至关重要,阻燃剂添加量将直接影响配方设计、成本核算、加工工艺与泡沫成品特性。朗盛测试数据还显示,Purventis® Core 能够维持泡沫力学性能,相较于使用传统阻燃剂的方案,可赋予泡沫更优异的刚性。

Purventis® 平台基于成熟技术构建,助力朗盛优化面向保温材料生产商的产品方案,帮助客户完善 PU/PIR 产品组合,从容应对持续变化的法规与市场需求。
