Rubber Stopper 32mm

32mm rubber stoppers are crucial in the pharmaceutical industry, providing effective seals for vials, syringes, and ampoules. These stoppers are typically made from high-quality natural rubber, ensuring elasticity and durability. The precise design of 32mm rubber stoppers ensures a perfect fit with various container specifications, preventing drug leakage and contamination. Additionally, these stoppers undergo strict quality control and sterilization processes, meeting the high hygiene standards of the medical industry.

In addition to maintaining the integrity of drug storage, the 32mm rubber stopper also ensures safe, accurate dosage delivery. When used on syringes, the stopper provides a secure seal that prevents fluid leakage during transport and administration.

High-Quality Material

The Rubber Stopper 32mm is made from premium natural rubber with a dense molecular structure and high strength. Professional testing shows its tensile strength reaches 15MPa, and elongation at break can achieve 300%. This makes the stopper resistant to breaking during use, maintaining good condition over time and providing reliable sealing for various applications.

Outstanding Elasticity

This rubber stopper features excellent elasticity, maintaining good shape recovery under different pressures and temperatures. Within the temperature range of -20℃ to 80℃, its elastic retention rate remains above 90%. This means it tightly fits the bottle mouth in both cold and hot environments, effectively preventing liquid leakage and ensuring safety and stability.

Good Wear Resistance

The specially treated rubber surface has a low friction coefficient and high wear resistance. After 10,000 friction tests, its wear is only 0.1mm, significantly lower than similar products. This ensures the stopper's sealing performance is not affected by wear over long-term use, extending its lifespan.

Strong Chemical Stability

The rubber stopper has good resistance to common chemicals, showing no significant chemical reactions or swelling when exposed to acids, bases, organic solvents, etc. After 72 hours of immersion testing, its volume change rate is less than 2%, stably maintaining its shape and performance. This makes it suitable for various chemical environments.
