Midland, Michigan -- Dow Chemical Co. has introduced a new grade of polyolefin elastomer for thermoplastic polyolefins (TPOs) used for automotive interior and exterior components, the company said in a 3 May announcement.
When compounded with polypropylene, the new material, which is called Engage XLT, delivers a combination of benefits not previously possible with other TPO impact modifiers, according to the statement.
Dow said Engage XLT provides a variety of benefits to compounders, moulders, vehicle manufacturers and consumers as it can â€œtake advantage of improved impact efficiency that enables lower elastomer loading in the TPO while still delivering excellent impact performance.â€
The chemical company added that lower elastomer loading results in higher TPO stiffness and melt flow which contributes towards improved fuel economy. Dow said that computer simulations have shown a reduction of up to ten percent in the total weight of a part made with Engage XLT.
The material was created as part of a series of solutions designed to address the needs of the automotive industry during an ongoing consumer study by Dow.
â€œEngage XLT is a result of Dow's commitment to creating products and solutions to help meet the needs of the automotive industry, from the compounders to the OEMs to the consumers,â€ said Dave Mitchell, marketing manager at Dow Elastomers.
The product is delivered in free-flowing pellet form that can be easily handled in large-scale continuous compounding operations.
