Butyl rubber stoppers have good properties in terms of seasonality, heat resistance, chlorination resistance, and aging resistance.
The butyl rubber stopper is commonly used in tubular glass vials, moulded glass vials, and glass bottles for injection, and it is capped with aluminum or aluminum-plastic (flip-off) caps.
The advantage of butyl rubber stopper:
1.Good adhesion, ease of cleaning, non-hardening and non-stickness.
2.Butyl rubber plug with coated surface, the coating will prevent potential contamination between the rubber contact surface and the medicine, thereby expanding the applications for the stoppers.
3.The butyl rubber stopper has been continuously developed and tested by the company to have the right strength, Effectively reduce instances of leakage during needle insertion, extraction and inversion -hanging.
4.Environment protection, non toxic.
5.Complete specifications, wide range of uses.
6.Super sealing and anti vibration function.
7.These rubber material have high elasticity,insolation, waterproof and excellent,wear resistant, aging resistant, high/low temperature resistant, anti-corrosion, dust proof.
8.Superior service system, with professional technical personnel, to provide customers with supporting and personalized services at any time.

The advantage of Bromobutyl Rubber Stoppers:
1.These rubbers have excellent properties of durability, elasticity, and resilience.
2.Size and color: Customize
3.Compared to other rubbers, bromobutyl rubber is usually lower in extractables and has excellent resistance to water and oxygen penetration.
4.Lower hygroscopicity and is a better choice for freeze dried / lyophilization product applications. Higher stability and generally have a longer shelf life.
5.Faster cure rates and a shorter scorch or cure induction period (more efficient production)
requires lower levels of curatives and enables one to use a wider range of accelerators.

Advantages of Chlorobutyl Rubber:
1.Better resistance to heat and is the preferred stopper for high-heat sterilization techniques.
2.Efficiently produced without the use of stabilizers.

Advantages of aluminium-plastic caps:
1.Excellent material, rich in texture, every detail is highly sophisticated, sturdy and durable.
Flat section, various specifications, multiple materials, good sealing.
2.One cap for multiple uses, can meet a variety of specifications for bottles, to meet the various needs of customers.
Beautiful shape, flat cap, smooth feel, thickened design, not easy to deform, rigorous process, wear-resistant and durable, long use.
Usually assembly with rubber stopper used for sealing injection bottles or infusion bottles.
3.Assembling in 100000 class workshop , alse We have pure water producing workshop, we wash the aluminum parts by pure water and ultrasonic equipment then dry them, to avoid any oil and aluminum scarps.
4.Sterilization method: autoclave sterilizer, Ethylene Oxide(EO), we can supply sterile caps.
5.Temperature resistance of plastic part: 135 degree centigrade.
6.Temperature resistance of aluminum part coating: 180 degree centigrade.
7.Workshop: 100 class cleaning workshop meets the GMP standard.
