SMC sheet yarn

SMC sheet yarn is a direct, untwisted roving treated with a special sizing. It is used to create high-performance composite parts through compression molding. It is suitable for composite products requiring high strength and excellent surface quality in the automotive, construction, and electrical industries.

Compatible Resins

Unsaturated Polyester Resin

Vinyl Resin

Detail

Parameters

Material properties

—

Cutting dispersion

—

The neat cutting and uniform length of the fiber bundles ensure the uniform distribution of the SMC sheet fibers, improving the molding fluidity and product appearance quality

Mechanical properties

—

High strength and high modulus provide good tensile, bending and impact strength, improving the structural performance of SMC products to meet the requirements of high-performance applications such as automobiles and electrical appliances

Water resistance

—

After being treated with the impregnation agent, it has good resistance to hydrolysis and moisture and heat. It is suitable for scenes with high humidity and strict environmental requirements, such as electrical insulation and outdoor components

树脂兼容

—

The sizing agent has good compatibility with thermosetting resin systems such as unsaturated polyester and vinyl ester, and has a fast wetting speed, which improves the density and overall strength of the product
