as a high performance offering for critical sealing components,
Kalrez® Spectrum KLR7075 perfluoroelastomer parts build
on the exceptional performance of Kalrez® 4079, the industry
standard for severe sealing applications. Customers will benefit
from longer seal life and increased mean time between repairs
due to the benefits of KLR7075 performance:
low compression set at 204°C for 70 hours (15%)
sealing force retention
thermal resistance, up to 326°C (620°F)
addition, KLR7075 offers broader chemical resistance and better
cool down set recovery than Kalrez® 4079, and provides a smoother,
glossier finish than other Kalrez® products.
customers in the chemical and hydrocarbon processing industries
have experienced exceptional seal performance in preliminary product
testing, especially in mechanical seal applications," said
Don Pittenger, Chemical Process Industry Marketing Manager, DuPont
Dow Elastomers. "We believe KLR7075 is an important addition
to the family of Kalrez® products, which have become the industry
standard for safe, reliable service."
