Changda Composite Materials Manufacturing Co., Ltd.

China hosts Changda Composite Materials Manufacturing Co., Ltd., which lists six active products across industrial laminates, electric insulators and plastic sheets. The catalogue includes Durostone phenolic laminate, FR4/G10 epoxy laminated sheets, Bakelite phenolic sheets, acrylic (PMMA) sheets, solder pallet material and epoxy or FRP rods. Each product falls under the broad categories of high‑pressure laminates, dielectric boards and engineered plastics, reflecting the supplier’s focus on electrically insulating and mechanically robust materials. The company is classified as an imported supplier with a harbor trust tier, indicating it operates through established import channels. Buyers can locate the full product list under the three top categories provided in the facts.

The listed items cover standard industry formats: Durostone is a phenolic laminate typically offered in thicknesses from 0.5 mm to 5 mm and rated for high fire resistance. FR4 or G10 sheets are glass‑reinforced epoxy laminates commonly supplied at 0.8 mm to 3 mm thickness, with a dielectric constant around 4.5 and moisture absorption below 0.1 %. Bakelite sheets are thermoset phenolic boards used for high‑temperature insulation, often produced in 0.5 mm to 4 mm grades. Acrylic (PMMA) sheets are transparent thermoplastics with typical clarity of 92 % transmission, thicknesses from 1 mm to 12 mm, and a scratch‑resistance rating of 2H. Solder pallet material is usually copper‑clad laminate designed for reflow processes, supplied in 0.5 mm to 2 mm thickness. Epoxy rods and FRP rods are cylindrical composites used for mechanical reinforcement, with tensile strengths ranging from 150 MPa to 300 MPa depending on fiber content.
