Product description

Bromobutyl Plug

Bromobutyl Plug are also called Bromobutyl Rubber Stoppers and Bromobutyl Stopper, which are commonly used to seal medicine vials and bottles for low permeability to gases and liquids, good resistance to chemicals, weathering and ozone, etc, also known as Pharmaceutical Plugs.
Bromobutyl Plug 
Bromobutyl Plugs are made of Bromobutyl Rubber material. As a kind of halogenated butyl rubber, Bromobutyl Plugs also have excellent resistance to weathering, ozone, and hot air; very good resistance to acidic and basic chemicals; very low permeability to gases and liquids; very good rheological properties, which can keep harmful substance from pharmaceutical.  
Compared to butyl rubber, Bromobutyl Rubber has a enhanced adhesion and faster cures.

 Bromobutyl Rubber Stoppers
Bromobutyl Plugs and chlorobutyl rubbrers Plugs are both commonly used in medicine vials and bottles sealing. Compared with chlorobutyl rubbrers stoppers, Bromobutyl Rubber Stoppers have advantages and disadvantages as following:
 
Bromobutyl Plugs- advantages:
a. Better stability and longer life span
b. More available vulcanization systems and higher cleanliness  
 Like polyamine vulcanization, during vulcanization process, It can avoid existence of harmful substance, such as sulfur (accelerant containing sulfur) and zinc oxide, ensuring higher cleanliness of stoppers and then reducing pollution and side-effects on pharmaceutical.
 
Bromobutyl Rubber Plugs- disadvantages:
a. There exist a terrible smell during high temperature sterilization.
  Bromobutyl Rubber Stoppers generally adopt sulfur vulcanization system, so heat resistance is worse slightly. Due to bromine element is relatively active, stoppers throw off a terrible smell during high temperature sterilization.
b. There is a greater influence in Hemolysis experiment
 During Sulfur vulcanization, bromobutyl Rubber Stoppers need to add a accelerating vulcanizing agents, which has influence on stopper’s Hemolysis experiment.

Xiamen Better Silicone Import and Export Company is specialized in mold-making (since 1998) and production of Bromobutyl Rubber Plugs according to customer’s 2D/3D designed drawings or samples. Therefore, we have rich experience and in-depth expertise in applications of bromobutyl Rubber stoppers for sealing medicine vials and bottles. We make three mold plates to avoid parting line on stopper’s surface for better sealing effect.
