Abstract

The invention provides a medicinal synthetic polyisoprene gasket composition, relating to the technical field of medical supplies. The composition is characterized by comprising the following components in parts by weight: 0-70 parts of polyisoprene, 15-25 parts of talcum powder, 1-3 parts of zinc oxide, 0.1-0.2 part of antioxidant, 0.01-0.1 part of accelerator, 1-3 parts of titanium dioxide and 0.01-0.1 part of carbon black. The composition has the beneficial effects that the composition has simple components and is convenient to prepare; and the prepared gasket has good sealability, is environment-friendly and hygienic, is pollution-free and ensures quality safety of liquor.

Description

technical field [0001] The invention relates to the technical field of medical supplies, in particular to a medicinal synthetic polyisoprene gasket composition. Background technique [0002] As soft bags in the pharmaceutical market gradually replace glass bottles and become the main packaging material in the market, polyisoprene gaskets also replace butyl rubber stoppers and become the leading product in the rubber stopper industry. The replacement of glass bottles by plastic soft bags has its inherent inevitability: better compatibility and stability than glass bottles, and better drug safety; A series of problems caused by fragmentation. Therefore, the replacement of glass bottles by soft bags is determined by internal laws and has its inevitability. The existing polyisoprene spacer has low supporting performance, relatively large resistance to steel needles (or plastic needles) during clinical puncture, and poor puncture performance. Contents of the invention [000...
