Polyolefin elastomers increase application options

In an effort to give molders new application options, DuPont Dow Elastomers is unveiling five new grades of Engage polyolefin elastomers. These developmental grades, based on ethylene butene, are designed to offer an improved balance of properties including processibility, impact strength, and high melt strength.

Several of the new grades are specifically aimed at automotive TPO applications and offer increased versatility and good impact properties. They?re designed for use in high-flow polypropylene compounds for the production of larger and lighter parts for consolidation. Potential applications include bumper fascia, cladding, and interior components. Other grades will target automotive interior applications and provide improved melt strength, softness, and feel. Commercial production is set to begin in 2003.

Following are the new grades:

ENX7467 A high-performance product offering good impact properties for TPO applications.

ENX7458 A broad molecular weight distribution product offering good flow properties and suited for plastics modification.

ENX7447 A high-flow, low-density product designed for use in combination with other elastomers for polymer modification.

ENX7380 With high molecular weight, good toughness, and melt strength, it can serve as an extender for SEBS or provide improved gloss control in TPOs.

ENX7270 A general purpose grade designed for polymer modification.
