Platinum-catalysed addition cure chemistry forms the foundation of an innovative new silicone curing technology, it has been confirmed.

Momentive Performance Materials has developed a system which uses ultraviolet light, rather than heat, to cure rubber and liquid silicone rubber.

The products, which are being branded under the Silopren and Addisil names, are capable of reducing cure times at low temperatures, while also protecting silicon rubber's properties.

As a result, the technology could help improve the performance of medical devices which combine silicone rubber with thermally-sensitive materials.

At present, a number of pharmaceutical drugs, electronic parts and low-temperature thermoplastics are unable to cope with the heat associated with traditional silicone curing.

The use of the platinum-catalysed addition cure chemistry enables the resulting products to boast high purity, while also minimising the level of extractables.

Holger Albrecht, Global Consumer Marketing Director at the firm, explained that the ultraviolet process will be able to save both time and money.

He said: "We are actively collaborating with customers to help them use our new technology to innovate, while continuing to build on our ultraviolet portfolio of products made from different silicone bases in different durometers.

"We are also proud of the fact that our ultraviolet technology can offer an alternative to conventional curing methods, and may offer the potential of lower impact on the environment."

Momentive Performance Materials is a world leader in silicones and advanced materials and delivers science-based solutions to its customers.
