热塑性材料供应商RTP扩大产品范围

根据最近签订的商标合约,特种复合材料供应商RTP公司(美国明尼苏达州,Winona,www.rtpcompany.com/cn/index.htm)将开始生产并出售预着色Radel R PPSF纤维聚合物(PPSU)和Udel(PSU) 聚砜树脂,新产品的商标由塑料供应商Solvay Advanced Polymers LLC 公司(比利时布鲁塞尔; www.solvayadvancedpolymers.com)所拥有。

根据合约,全世界的客户可以通过RTP 公司方便快捷的得到他们想要的小批和中批Radel R PPSU及Udel PSU复合材料。该合约将先在北美和欧洲实行,至今年6月将推广至亚洲。全球医疗市场部经理Josh Blackmore说。

Radel R PPSU是一种非结晶树脂,广泛用于整形外科领域,具有热稳定性、高强度、水解稳定性、透明和耐环境应力破裂性等特点。Blackmore解释道:有10种不同颜色可供医疗器械OEM厂商和加工商选择,这些材料都已通过生物相容性测试。客户还可通过 RTP公司定制其需要的颜色。

另外,该公司与Biosafe公司(美国宾州匹兹堡, www.biosafeinc.com)签订的销售和生产合约允许RTP 公司使用Biosafe的硅烷抗菌技术生产各种抗菌产品。专利产品硅烷浓缩剂可作为色母粒添加剂,用于多种挤出和注塑工艺中。

RTP Color总经理Jean Sirois称,硅烷抗菌技术可赋予塑料永久抗菌的特性,与银质添加剂相比,成本更低,使用更方便。在最终产品中,这些抗菌色母粒活性成份仅需0.25-0.5%即可。与传统的抗菌剂如银或三氯生相比,它更有竞争力、更安全、更高效。

Sirois说,银用于高透明度的树脂时,会使树脂变黄或失去光泽,而硅烷抗菌剂可提高树脂的着色性能且不影响其光学性能。此外,硅烷添加剂还可防止染色及由细菌、真菌、霉菌引起的物质降解和藻类产生的气味、褪色、生物污着等一系列影响外观的问题。硅烷抗菌剂被FDA列为一种可用于医疗器械的改性剂。
