DSMPREL012 - 22/05/2009

Quality and innovation:


Heerlen, 22 May 2009 – DSM Elastomers has introduced a new EPDM grade that can be used on the one hand as shear stable viscosity index improver (VII) for the Petroleum Additives (PA) market and on the other hand as a processing additive for rubber applications.

Keltan® 1200A, which will be available from June 2009, is one of the first of a new range of high performance EP(D)M grades to be produced with DSM Elastomers’ new state-of-the-art Reactive Extrusion (REX) technologies. It was originally tested as development grade DE5001, and has been well received in the market.

Because new Keltan® 1200A is an ultra-low viscosity product, with a Mooney rate of approximately 2.5 MU (ML(1+4)@125°C), the product has a number of key processing benefits for the conventional rubber market. Its excellent wetting properties for fibers and fillers and improved adhesion in rubber compounds, makes it highly suitable for applications requiring tack, such as conveyor belts and micro V-belts. Keltan® 1200A is able to reduce viscosity in difficult to mix compounds such as highly filled, stiff compounds. These key benefits of the material were highlighted at the 2009 International Forum on Advanced Rubber and Plastics (IFARP) for Rubber Belt, which was held recently in Qingdao, China.

In demanding applications – for instance in wire & cable or potable water - Keltan® 1200A may be used as a non-extractable oil replacement. Other typical application areas include corner moulding, water seals and gaskets, soft roller compounds, textile adhesion, calendaring and fibre treatment, fiber dispersions, seam tapes and adhesive tapes for roof sealing systems.

In addition to Keltan® 1200A, a number of new REX grades are under development and/or have reached the phase of pre-commercial customer evaluation. These include Keltan PA1305, a mid-Shear stable VII polymer and Keltan®1446A for curable plasticizer and high flow applications.

The introduction of Keltan® 1200A underlines DSM Elastomers’ commitment to high quality, high standards of service and security of supply, which the company sees as its strategic pillars in meeting – and exceeding - market requirements.
