HexTow® Chopped Fiber

Product catalog summary
Product Overview: HexTow® is a PAN-based carbon fiber available in 1/4 inch chopped lengths, designed for compatibility with various resin matrix systems. The fibers are lightly held together by sizing, which aids in processing.
Specifications: The chopped fibers are small, thin, rectangular flakes measuring 1/4 inch long and 1/8 to 1/4 inch wide. The sizing systems improve bonding and bulk density, facilitating blending and mechanical feed operations.
Properties and Benefits: Adding chopped carbon fiber to molding compounds enhances strength, modulus, fatigue and creep resistance, thermal expansion, conductivity, friction and wear resistance, and reduces shrinkage.
Product Variants: Four types of chopped carbon fiber products are available, with varying percentages of IM and AS carbon fibers. All products have a fiber length of 0.25 inches (6.4 mm) and are packaged in 40 lbs (18.1 kg) boxes.
Sizing Systems: Three sizing types are available, each with specific compatibility with different resin matrices such as polyamide, polycarbonate, and epoxy. Sizing content ranges from 3% to 8% by weight.
Certification and Customization: The carbon fiber is manufactured to Hexcel industrial specification HS-CP-1000, with a Certification of Conformance provided with each shipment. Custom sizing with other resins is available upon request.
Packaging: The product is packaged in polyethylene bags within boxes to prevent damage, labeled with fiber type, lot number, and net weight, complying with freight regulations.
Safety Information: Users should read and understand the Material Safety Data Sheet (MSDS) before using the product.

Catalog excerpts

HexTow® Chopped Fiber-1

HexTow®, PAN based carbon fiber is available in 1/4 inch chopped fiber lengths, sized for compatibility with various resin matrix systems and processes. The chopped product is small, thin, rectangular flake, 1/4 inch long by 1/8 to 1/4 inch wide. The individual filaments are lightly held together by the sizing and will break apart during subsequent processing. The specially formulated sizing systems, in addition to improving bonding, produce a higher bulk density that aids in blending operations and in the flow through mechanical feed systems. Addition of chopped carbon fiber to molding compounds produces a material that exhibits high strength and modulus, excellent fatigue and creep resistance, low thermal expansion, electrical and thermal conductivity, excellent friction and wear resistance, and low shrinkage.
