To Distribute Momentive Performance Materials’ Elastomers

Albany, N.Y.-based silicone and advanced materials provider Momentive Performance Materials Inc.
has announced that — an online distributor of fine and specialty chemicals — will now
serve as the authorized distributor of Momentive’s general purpose and custom elastomer products in
North America.

Momentive’s silicone elastomers exhibit low toxicity, electrical insulation and resistance to
harsh temperature and weather environments, among other properties, and are used in a variety of
industries. The portfolio includes ultraviolet light cure elastomers for use in medical device
applications requiring heat resistance; economically priced custom low-density materials; and
antimicrobial elastomers for use in healthcare and consumer product applications. Among the latter,
the company’s StatSil™ elastomer helps prevent the transmission of microbial infections in
hospitals and won a 2009 Frost & Sullivan Product of the Year Innovation Award.

“This agreement is a natural extension of a successful relationship that brings together
ChemPoint’s extensive experience in specialty products and diverse markets with Momentive
Performance Materials’ superior offering of general purpose and custom silicone products,” said
Thuan Nguyen, commercial leader, distributor sales, Momentive Performance Materials. “Together, we
look forward to the continued delivery of product and service excellence that our customers need to
achieve their own innovation goals.”
