What Is Platinum Cured Silicone Rubber?

by Accurate Rubber Accurate Rubber Corporation

In a platinum-based silicone cure system two different chemical groups react in the presence of platinum. Unlike the traditional Peroxide cured materials Platinum Cured Silicone does not use peroxides as part of the catalysing process. These can sometimes leave trace elements after post cure causing contamination.

As a result Platinum Curing is becoming a more popular choice in many industries including medical, food, drink or dairy applications.

Benefits of platinum cured silicone

There are a range of benefits when choosing platinum cured silicone over alternatives:

High tear strength
excellent translucency so more visibility through the material
non yellowing
no peroxide by-products
highly hydrophobic
extended life in Peristaltic pumps
Platinum cured silicone applications
Due to its advantages as listed above there are many industries now seeking platinum cured silicone products. These include:

Pharmaceutical and biotechnology applications;

platinum-cured silicone rubber tubing is an excellent choice for fluid transfer. Its high temperature resistance and fewer potential leachables make it a perfect fit for medical use. Silicone maintains the purity of sensitive fluids due to its excellent biocompatibility and chemical inertness. This type of tubing has smooth surfaces and lower protein binding levels which is another selling point for this particular application.

Food and Drink applications;

platinum-cured silicone tubing has revolutionised the transfer of liquids in drinks machines. Traditional peroxide-cured silicone tubing can impair the taste of liquids due to tainting, platinium cured tubing does not have this down side. It's high tensile strength also means that it's an ideal fit for food industries.

Dairy applications;

Platinum cured silicone is ideal for use in the dairy industry due to its high mechanical wear and excellent tear strength. In comparison to conventional black rubber tubing often used for milking, platinum cured tubes do not harden and corrode with use. Instead, this extremely durable product is made using highly polished dies to create an extra smooth inner bore to improve flow rate and hygeine levels.
