30 May 2024 Platinum Cured Silicone


In the world of biopharmaceuticals, the materials used in manufacturing and processing are crucial for ensuring product safety and efficacy. Among these materials, platinum cured silicone stands out as a top choice for many applications. This remarkable material offers numerous advantages that make it indispensable in the biopharmaceutical industry.

Platinum cured silicone is known for its exceptional purity, durability, and versatility. These properties make it ideal for various biopharmaceutical applications, from fluid transfer systems to sealing solutions. In this article, we’ll explore what makes platinum cured silicone so special and why it is preferred over other types of silicone.

What is Platinum Cured Silicone?

Platinum cured silicone, also known as addition-cured silicone, is a type of silicone that uses platinum as a catalyst in the curing process. This method of curing results in a material that is highly pure and free from by-products, making it suitable for
sensitive biopharmaceutical environments.

Key Properties: 

High Purity: Platinum cured silicone is known for its extremely low levels of impurities, which is essential for maintaining the integrity of biopharmaceutical products.
Non-toxic and Non-reactive: This type of silicone does not leach chemicals into the products it comes into contact with, ensuring that there is no risk of contamination.
Durability: It offers excellent resistance to wear and tear, maintaining its properties over a long period of time.
● Flexibility and Elasticity: It retains its shape and flexibility even under stress, making it perfect for dynamic applications.
Chemical Resistance: It withstands a wide range of chemicals, making it versatile for various biopharmaceutical processes.
Temperature Resistance: It performs well in both high and low temperatures, which is crucial for processes that require sterilisation.

Comparison with Other Silicones:

● Platinum Cured Silicone vs Peroxide Cured Silicone: Platinum cured silicone is often preferred over peroxide cured silicone due to its higher purity and better performance in biopharmaceutical applications. Peroxide cured silicone may leave residues that can contaminate biopharmaceutical products, making it less suitable for sensitive environments.

By understanding these properties, it’s clear why platinum cured silicone is the material of choice in the biopharmaceutical industry. Its unmatched purity and performance characteristics ensure that it meets the stringent requirements of this
demanding field.
