Material Notes:
CALIBRE® 890 series polycarbonate resins are a general purpose, superior ignition resistant grade equipped with a mold release package. The CALIBRE 890 series resins exhibit a high heat resistance, high impact and are rated V-0 at 1.6 mm, 5V at 3.2 mm according to UL-94(1).The CALIBRE 890 series resins are typically used in building and construction and in business equipment applications.Available Melt Flow Rates: 10, 20Associated products: CALIBRE 891: including a mold release package CALIBRE 893: including a mold release and UV stabilizer package.These numerical flame spread ratings are small scale test values and are not intended to reflect hazards presented by these or any other materials under actual fire conditions.Ignition resistant chemical additives increase resistance to burning from minor flame sources and permit properly manufactured end products to meet the requirements of certain flammability tests, but resins will burn rapidly under the right conditions of heat and oxygen feed.Data provided by Dow Chemical.This product line was spun off from Dow Chemical to Styron in 2010.
