SMC Waffle Board Introduction

SMC waffle board is a sheet molding compound (SMC) using unsaturated polyester resin as the matrix and glass fiber as the reinforcing material, formed by high-temperature and high-pressure molding. Its waffle honeycomb structure endows it with characteristics of light weight, high strength, precise dimensions, and a smooth surface, along with excellent corrosion resistance and insulation. It is widely applied in semiconductor cleanrooms, high-end electronics manufacturing workshops, and other fields with strict requirements for cleanliness and flatness.

Production Process

1.Raw Material Preparation

Mix unsaturated polyester resin, glass fiber, fillers and other additives according to the ratio, stir and impregnate with special equipment to make SMC sheets. Strictly control temperature, humidity and mixing time to stabilize material properties.

2.Cutting and Pre-forming

Cut SMC sheets into specified sizes, place them into molds for pre-forming to determine the initial shape of the board.

3.Compression Molding

Put pre-formed sheets into high-precision molds, cure and crosslink at 120℃-150℃ and 10-20MPa. After holding pressure, high-strength and high-precision waffle boards are formed.

4.Post-treatment

Trim edges and polish the surface after demolding to remove burrs. Surface coating can be applied when necessary to enhance protective performance.

Product Characteristics

1.High Strength and Lightweight

The unique waffle honeycomb structure ensures the board maintains high strength while weighing only 1/3 to 1/5 of traditional concrete boards. This effectively reduces the load on building structures and lowers transportation and installation costs.

2.High Precision and Flatness

Formed by high-precision mold compression molding, the board features precise dimensions and a flatness of ±1mm/m². This meets the strict flatness requirements of high-end manufacturing industries like semiconductors, ensuring stable operation of precision equipment.

3.Excellent Corrosion Resistance

SMC material shows good tolerance to chemicals such as acids, alkalis, and salts, enabling long-term use in humid and corrosive environments. It is resistant to aging and deformation, with a service life of over 30 years.

4.Superior Insulation Performance

With excellent electrical insulation, the board has a surface resistivity ≥1×10¹²Ω and volume resistivity ≥1×10¹³Ω・cm. It effectively prevents static electricity accumulation, avoiding damage to electronic components and ensuring production safety.

5.Good Flame Retardancy

With an Oxygen Index (OI) ≥30%, it meets the standards for flame-retardant materials. It is difficult to ignite and can effectively prevent fire spread, providing reliable fire safety for industrial production.

6.Low Dust Emission

The board’s smooth and dense surface is less prone to dust adsorption. In cleanrooms, its dust emission is extremely low, complying with standards like ISO 14644-1 to maintain high cleanliness in the production environment.
