The curing system used in silicone products directly affects purity, colour, odour, mechanical performance and applications. The two most widely used options are the platinum curing and peroxide curing systems.
What is platinum-cured silicone?
Silicone vulcanised with a platinum catalyst is known for its low odour, high transparency and clean surface. With suitable raw materials and process conditions, it is used in food, medical and sensitive fluid-handling applications.
What is peroxide-cured silicone?
The peroxide system is an economical and reliable curing method with a wide range of industrial applications. It can be used to manufacture profiles, cords, seals and technical tubing in various hardnesses and colours.
Key differences
- Purity and odour: Platinum-cured products offer lower odour and cleaner surfaces.
- Appearance: The platinum system offers advantages for products requiring high transparency.
- Cost: Peroxide curing is more economical for many general industrial applications.
- Application: Selection should be based on temperature, contact fluid, standards and duration of use.
Which system should you choose?
No single system is right for every application. Operating temperature, pressure, chemical contact, hygiene conditions and certification requirements should be assessed together.
