The Dow Chemical Company has expanded its catalyst system offering with Consista D7000 Donor, designed specifically for high melt flow (HMF) applications.

The first product in Dow’s new Consista portfolio of advanced catalyst systems, Consista D7000, enables polypropylene manufacturers to achieve the performance differentiation needed to enter premium markets, while realising the benefits of better on-stream time, better plant operability and reduced production costs, said a top offcial.

“Consista D7000 helps polypropylene producers differentiate their products and seize profitable market opportunities,” said Cherie H Wrenn, product market manager at Dow Basic Plastics Licensing and Catalyst, a Dow business unit that licences Unipol Polypropylene Process Technology.

“As part of the complete package of optimised solutions we bring to our customers, Consista D7000 delivers advantages throughout the entire value chain,” Wrenn noted.

“It makes transitioning between product grades smoother and faster, improves the performance characteristics of the finished product, and reduces the use of peroxide, thus bringing down resin manufacturing costs,” he added.

Consista D7000 was developed to optimise high-melt impact copolymer polypropylene resins, the type of polypropylene plastic used in automotive interior applications and food contact applications – all challenging but financially rewarding markets for manufacturers.

Specific requirements met
For each of these segments, Consista D7000 helps meet specific quality requirements – from high impact/stiffness balance, to improved polymer taste/odour profile in food contact applications, to reduced C emissions, the volatilised organic chemicals responsible for the “new car” smell. 

In commercial trials, Consista D7000 has been validated by select users of the Unipol Process and Shac Catalyst, the company said. The new product will be a boon to the market.
