New Vinyl Impact Modifier Achieves Highest Impact Efficiency Rating, Plus Offers Superior Gloss and Processing Performance

PHILADELPHIA--(Business Wire)--
Responding to needs expressed by vinyl compounders, extruders and fabricators of
window profiles for enhanced impact performance, The Dow Chemical Company
(NYSE:DOW) today announced the availability of a new, superior vinyl impact
modifier - Paraloid KM-X100 Pro. Tests have shown that the product`s exceptional
impact efficiency should exceed all competitive offerings. This fully formulated
all-acrylic material fulfills the major needs for reducing extruded vinyl
processing costs: it allows lower use levels, gives a wider processing window
for lower melt temperatures, and provides fast fusion for higher output rates
and maintaining gloss targets. Dow states that window profiles produced with
Paraloid KM-X100 Pro also transform vinyl window fabrication during cutting,
routing and punching operations by reducing breakage and chip scrap.

"Just over a year ago we launched our Paraloid KM-4000/5000 series that enabled
customized vinyl compounds to match specific performance requirements," says
Steve Rapacki, technical service manager for Vinyl Additives. "Now, with even
better impact performance and the wider processing window made possible by
Paraloid KM-X100 Pro, compounders have a unique opportunity to extrude window
profiles that meet their specific performance requirements for superior impact
resistance, higher gloss finish, and lasting durability against UV exposure."
According to Rapacki, company tests have demonstrated that Paraloid KM-X100 Pro
toughens vinyl windows reliably across a wide range of processing conditions,
and ladder studies show use levels of 4 phr and below can deliver excellent
impact performance without compromising high gloss.

Vinyl window profiles lead the market for new and replacement windows because
compounders and extruders are constantly improving performance and appearance.
In fact, two-thirds of vinyl manufactured today finds application in numerous
building and construction materials where its performance, ability to replicate
desired finish texture and appearance, and colorfastness under all weather
conditions hold great appeal for consumers. "We believe Paraloid KM-X100 Pro
will please everyone in the value chain, from compound formulators who want low
use cost, to those who desire to maintain the traditional toughness of vinyl
window profiles," adds Rob Martin, Dow market manager for Plastics Additives.

Dow encourages recyclability of all vinyl products. In the case of window
profiles, longer life cycle and the elimination of continual painting of windows
both meet the company`s principles for sustainability.
