Kaerda Sheet Molding Compounds (SMC)

High-Performance Composite Solutions

What is Sheet Molding Compound (SMC)? Sheet Molding Compound (SMC) is a high-strength, fiber-reinforced thermoset composite material, delivered in a ready-to-mold sheet form. At Kaerda, our SMC is primarily composed of high-quality thermosetting resins (such as Unsaturated Polyester – UP, or specialized Epoxy for demanding applications), precisely chopped glass fibers (GF), and carefully selected fillers and additives.

Our formulations are enhanced with various functional additives, including low-profile additives for superior surface finish and dimensional control, pigments for in-mold color, mold release agents for efficient processing, and catalysts to control curing characteristics. This results in a stable, highly moldable material engineered for producing complex, high-performance components.

Kaerda develops and manufactures its SMC in-house, ensuring complete control over quality and formulation. Our dedicated SMC production lines process these compounds into continuous sheets, typically sandwiched between polyethylene films for ease of handling and storage.

Key Features & Advantages

  • Lightweight & High Mechanical Strength: Ideal for structural parts and weight reduction.
  • Superior Electrical Insulation: Suitable for demanding electrical applications.
  • Outstanding Fire Resistance: Formulations available to meet stringent FST (fire, smoke, toxicity) standards for safety-critical applications.
  • Corrosion & Weather Resistance: Exceptional durability for outdoor use and exposure to harsh chemical environments.
  • Excellent Thermal Stability: Maintains mechanical properties and integrity at elevated temperatures.
  • Precision Dimensional Control: Very low to “zero shrinkage” characteristics for high-precision parts.
  • Design Versatility & Parts Consolidation: Allows for complex geometries and the integration of multiple functions into single molded parts.
  • Class A Surface Finish & In-Mold Colorability: Achieves smooth, paint-ready surfaces; can also be molded in custom colors.
  • Cost-Effective Solution: Often replaces traditional materials like metals or thermoplastics, offering benefits in weight, processing, and lifecycle costs.

Solutions & Customization

Standard & Specialized Grades:

  • Kaerda offers a comprehensive range of SMC formulations to meet diverse application needs, from general-purpose grades to highly specialized compounds.
  • This includes our advanced Epoxy SMC, specifically developed for high-performance applications such as electric vehicle battery casings, offering superior mechanical strength, fast curing, and excellent corrosion resistance.

Tailored Formulations for Your Application:
