Product Detail

Product Tags

This product is a Assembled Roving for high-performance structural grade SMC. The yarn surface is coated with a silane composite sizing, which is suitable for reinforcing unsaturated polyester resins and vinyl resins.

This product is a Assembled Roving made of alkali-free glass wire drawing. It adopts a special splitting and splitting process. The type 448 has a fast infiltration speed in styrene and a low resin adsorption capacity. It can also be completely infiltrated under the condition of high glass fiber content. With very good flow properties in resin, Model 456 is suitable for high viscosity paste, high machine speed, thick sheet production.

The product is used in SMC products of high temperature molding process, such as bathroom products that require high surface quality and colorability. Produces low-shrinkage sheet and can also be used for low-profile sheet production. Typical products are: various auto parts, door skins, water tanks, electrical parts, etc. Production of truck parts, car chassis, hoods, etc.
