一次性注射器填充级HDPE专用料的研制

DEVELEPMENT OF FILLED GRADE HDPE MEDICAL SPECIAL MATERIAL FOR SINGLE USE SYRINGE

通过对母料载体树脂的筛选,无机填料的选择,添加性能优良的耐辐射助剂,制成了具有耐辐射性能、加工性能良好的母料,该母料的制备工艺简单。本文所述的填充级HDPE专用料是将HDPE与填充母料经过简单掺混制成的。经测试专用料满足国家医药标准YY 0114—93《医用输液、输血、注射器聚乙烯专用料》的要求。制品厂试验表明:该填充级的HDPE专用料加工性能良好,用该填充级HDPE专用料注射成型的注射器芯杆装配成一次性注射器满足国家专业标准ZBC 31009—87《一次性无菌注射器》的要求。该填充母料的加入可大大降低材料的成本,100份HDPE 7006A可添加67份填充母料,该填充级专用料的价格比HDPE树脂降低约1500元/吨,因此该填充级HDPE专用料的推广和使用具有良好的经济效益。

A matrix material with radiation resistance & well processability was made by a simple processing technology of selecting matrix resin, inorganic filler & adding well property radiation resistant additives. The filled grade HDPE special material stated in this paper was made of HDPE & matrix material by simple mixing. Test show that the special material meets the requirements of the medicine standard of china YY 0114-93(Special material PE using for medical infusion, blood transfusion & syringe). The test of processing show that this filled grade HDPE special material possesses well processability, and the single use syringe fitted with core plug injecting with this material meets the requirements of the special standard of china ZBC 31009-87《Sterile hypodermic syringe for single use》. Adding this filled grade special material can reduce the coat greatly, for 100 portions of HDPE 7006A can add 67 portions of this matrix material, and the price of this material is less 1500YUAN/ton than HDPE resin, so the spreading & using of this filled grade HDPE special material has well economic results.
