EPDM utilizes new catalyst technology

Nearly five months after an official ground breaking on April 24, DSM Elastomers says an upgrade to its existing EPDM facilities in Geleen, the Netherlands is on schedule and will allow it to apply a new catalyst technology, with initial production coming shortly. The technology will produce Keltan ACE materials, with ACE short for Advanced Catalysis Elastomers.


To be commercially available in early 2009, these products will contain high amounts of 2-vinyl-5-norbornene (VNB) as third monomer and provide excellent peroxide curing efficiency. DSM says they allow cost-effective compounding of Keltan formulations that require peroxide curing, with customers able to lower the amount of peroxide used while maintaining material properties and improving the cost/performance balance. In addition  to savings on cross linking peroxide, the reduction of peroxide provides benefits in terms of reduction of bloom, odor, and taste, as well as improvement of electrical properties and heat resistance.

DSM says compounds can also be loaded with much higher levels, while maintaining material properties. Ultimately, DSM believes the balance of physical properties and high-temperature resistance can be “markedly improved”.
