A Comprehensive Guide to Butyl Rubber Stoppers in China
Butyl rubber stoppers are essential components in various industries, particularly in pharmaceuticals. Their airtight and watertight properties make them ideal for sealing vials and bottles, ensuring product integrity. China is a major producer of these stoppers, offering a wide range of types and specifications to meet diverse needs. This guide delves into the world of butyl rubber stoppers manufactured in China, exploring their technical aspects and variations. Companies like Xiamen Better Silicone Rubber Co., Ltd (www.better-silicone.com) are key players in this market.
Understanding Butyl Rubber and its Properties
Butyl rubber, also known as IIR (Isobutylene Isoprene Rubber), possesses exceptional chemical and thermal stability. Its air and watertightness are significantly superior to natural or styrene butadiene rubber. This makes it a preferred material for applications requiring a robust seal, such as medical and pharmaceutical packaging. The low permeability of butyl rubber ensures the contents remain protected from external contaminants. This property is a key selling point for manufacturers like those listed on www.tradewheel.com.
Variations in Butyl Rubber Stoppers
Two common types of butyl rubber stoppers are bromobutyl and chlorobutyl rubber stoppers. These are derivatives of butyl rubber, created by introducing halogen elements. This modification enhances processing capabilities and expands their application range. The choice between bromobutyl and chlorobutyl often depends on specific needs for storage stability and purity. Many Chinese manufacturers, such as those found on www.Chinamedica.com, offer both types.
Technical Features Comparison
The following table compares the key technical features of bromobutyl and chlorobutyl rubber stoppers:
| Feature | Bromobutyl Rubber Stopper | Chlorobutyl Rubber Stopper |
|---|---|---|
| Stabilizer | Usually requires stabilizer addition | Typically does not require stabilizer addition |
| Storage Stability | Lower, prone to self-vulcanization | Higher, more stable |
| Purity | Lower due to stabilizer presence | Higher, purer due to lack of stabilizer |
| Cure Reactivity | High, wider range of curing systems available | Lower, more limited curing system options |
| Cure Rate | Faster | Slower |
Manufacturers like Taizhou KangLong Medical Treatment Technology Co., Ltd (www.klstopper.com) emphasize GMP standards in their production processes, ensuring high-quality products.
Types of Butyl Rubber Stoppers Based on Application
The design and dimensions of butyl rubber stoppers vary greatly depending on their intended use. Here’s a comparison of some common types:
| Type of Stopper | Application | Size Variations | Key Features |
|---|---|---|---|
| Infusion Bottle Stoppers | Intravenous drug solutions | Various diameters (e.g., 13mm, 20mm) | High purity, low piercing force, good seal |
| Antibiotic Bottle Stoppers | Antibiotic solutions | Various diameters | Sterility, chemical resistance |
| Freeze-Dry Bottle Stoppers | Lyophilized pharmaceuticals | Various diameters | Vacuum-tight seal, maintains sterility |
| Oral Liquid Bottle Stoppers | Oral liquid medications | Various diameters | Good chemical resistance, prevents leakage |
| Vacuum Vessel Stoppers | Vacuum sealed containers | Various sizes and shapes | Maintains vacuum, protects contents from oxygen |
