DCPD

Construction equipment (Excavator) Tool box DCPD’s mechanical material property & moldability are superior so it is possible to manufacture the product

with a refined design. As a result, it is widely used for industrial applications such as automotive interior, heavy

equipment and agricultural machinery.

What is DCPD (Dicyclopentadiene)?

DCPD is a thermosetting resin which facilitates the forming of large and complicated products in short periods

of time. Using the reaction injection molding (RIM) method, DCPD liquids are mixed, going through the

polymerization process in the mold, and then become the form of the desired product.

Merits• Large mold : Low-viscosity material makes it easy to manufacture larger and more complex products.

• Light-weight : Low specific gravity(1.03) based raw material improves the fuel e�ciency and reduce

the emission.

• Shock resistance : Achieves shock tolerance without adding glass fiber.

• Low temperature characteristics : Low impact strength adaptable to - 40°C

• Productivity : Short response time saves related costs.

SMC

Construction Equipment (Excavator) Engine CoverSMC’s mechanical material properties ensure its popular use in a wide variety of industrial

applications such as automotive interior, heavy equipment, and agricultural machinery.

What is SMC?

SMC stands for ‘sheet molding compound’

It is the sticky sheet made from the unsaturated polyester mixing material & resin based

compound and fiberglass. The sheet is formed into a desired shape through the curing & press process.

SMC is a thermosetting special compound.

Merits• Dimensions stability : Excellent dimensional stability due to low retraction rates after molding.

• Outstanding for use in electrical properties, such as insulation resistance, arc-resistance, and heat resistance.

• Physical properties : Uniform in fiberglass, high corrosion resistance, weathertightness, excellent anti-vibration

damping characteristics due to superior mechanical strength.

• Light-weight : Low specific gravity(1.8) based raw material improves the fuel e�ciency and reduce the emission.

• Design : Excellent design freedom.
