2026/05/09Clicks：9699
	1. Introduction

Platinum cured silicone tubing is widely recognized as one of the highest quality silicone tubing solutions used in industries requiring exceptional purity, flexibility, and safety.

Compared with peroxide-cured silicone tubing, platinum cured silicone tubing offers:

Lower extractables

Better purity performance

Improved transparency

Enhanced biocompatibility

Reduced odor and taste transfer

Because of these advantages, platinum cured silicone tubing is extensively used in:

Biopharmaceutical manufacturing

Food and beverage processing

Medical equipment

Laboratory systems

High purity fluid transfer applications

As modern industries demand cleaner and safer fluid systems, platinum cured silicone tubing has become an increasingly important solution.

2. What Is Platinum Cured Silicone Tubing?

Platinum cured silicone tubing is manufactured using a platinum-based curing process rather than traditional peroxide curing.

During production:

Platinum catalyst creates cross-linking within the silicone material

No peroxide by-products remain after curing

The tubing achieves higher purity and cleaner performance

This manufacturing method significantly improves the tubing’s cleanliness and biocompatibility.

3. Platinum Cured vs Peroxide Cured Silicone Tubing

Understanding the difference between curing methods is important when selecting silicone tubing.
