<p>PURPOSE:To provide a rubber plug for medical containers which is small in puncture resistance of a needle, has no problems in resealability after the passing through-of the needle, has a good gas barrier property, has high mechanical properties and excellent rubbery elasticity and can be injection molded. CONSTITUTION:This rubber plug for medical containers consists of a dynamically crosslinked thermoplastic elastomer formed by dispersing 55 to 90wt.% nearly completely crosslinked butyl rubber having 0.1 to 4mum particle sizes into 10 to 45wt.% crystalline polypropylene.</p> |
