Momentive Presents Next Generation Silicone Rubber Solutions at IEEE PES Transmission and Distribution Conference

Momentive Performance Materials will showcase a wide range of
silicone rubber solutions for electrical utilities and power delivery
professionals at the 2008 IEEE PES Transmission and Distribution
Conference (Booth 1888), April 21-24 at McCormack Place in Chicago.
These solutions include Silopren* Electro silicone rubbers for
potential use in high-voltage insulation, rod insulation on, and
hollow-core insulation for, transformer and circuit breaker
applications, and Silopren Electro and Silopren LSR silicone rubbers
for potential use in cabling joints and terminations.

"The latest generation of liquid silicone and high consistency
rubbers are allowing us to help our customers manufacture more complex
products, often while controlling their production costs and raising
their productivity," said Holger Albrecht, Elastomers Global Marketing
Manager, Momentive. "From crucial insulation applications to more
efficient cable accessories, these materials are enabling those in the
transmission and distribution industries to create stronger, safer

more robust products."

Momentive´s Silopren silicone rubbers provide a number of key
performance properties, including arc and tracking resistance

hydrophobicity recovery (even in highly polluted areas), excellent
weather, ozone and UV stability, easy processing with short production
cycles, colorability, low weight/density, excellent electrical
insulation and outstanding performance in a wide temperature range.

Momentive´s materials can be easily integrated into both
hollow-core insulation, including housing for transformers and oil
circuit breaker applications, and long rod insulation, to maintain the
keep distance between high voltage lines and construction parts with
ground potential. They can also play a key role in the manufacture of
connecting parts, cable terminations and switch gear accessories

helping smooth electrical field lines on medium and high voltage
cables, while protecting cables and conductors against environmental
hazards.
