Dow CALIBRE® 300EP 22 Polycarbonate, General Purpose

 

Subcategory: Polycarbonate; Thermoplastic

Key Words: PC

Material Notes:
CALIBRE® 300EP series resins are general purpose polycarbonate resins and can be supplied with a mold release package, a UV stabilizer package or both. CALIBRE 300EP resins exhibit an excellent physical property balance of heat resistance, transparency and impact strength. The CALIBRE 300EP resins have a UL-94 rating of V-2(1). In addition the high melt flow rate allows complex parts to be easily molded.

The CALIBRE 300EP series resins are typically used for appliances, storage media housings, electrical components and lighting.

Available Melt Flow Rate: 22.

Associated products:
CALIBRE 300EP: without a mold release and UV stabilization package
CALIBRE 301EP: including a mold release package
CALIBRE 302EP: including a UV stabilizer package
CALIBRE 303EP: including a mold release and UV stabilizer package.

(1) 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.
