SMC Sheet

SMC sheet molding compound is a high-performance new environmentally friendly composite material. Our company has extensive experience in researching SMC since 2009.

SMC stands for Sheet Molding Compound, which is a type of sheet molding compound made primarily from SMC specific yarn, unsaturated resin, low shrinkage additives, fillers, and various additives. It first appeared in Europe in the early 1960s, and around 1965, the United States and Japan successively developed this craft. In the late 1980s, China introduced advanced SMC production lines and processes from abroad.

SMC has superior electrical performance, corrosion resistance, lightweight, easy and flexible engineering design, and its mechanical properties can be comparable to some metal materials. Therefore, it is widely used in transportation vehicles, construction, electronics, electrical and other industries.

(1) Superior electrical performance and corrosion resistance

Capable of withstanding various harsh environments, including chemical corrosion and electrochemical corrosion, with good durability.

(2) Lightweight and high-strength

It is lighter than metal materials such as steel and aluminum, effectively reducing the weight of the product while maintaining high strength and stiffness.

(3) Engineering design is easy and flexible

Various sizes and shapes can be designed according to requirements, maximizing imagination and enabling rapid prototyping.

(4) Excellent mechanical performance

It can be comparable to some metal materials and can replace aluminum, steel, etc., meeting the needs of different parts and components.

(5) Good dimensional stability and appearance

By adding low shrinkage agents and using low shrinkage resins, the product can maintain dimensional stability over a wide temperature range and have a smooth surface, making it possible to produce products in various colors.

(6) Excellent heat resistance and aging resistance

The heat deformation temperature is higher than that of ordinary thermoplastic, with excellent aging resistance and long service life.

(7) Good electromagnetic shielding performance

Carbon fiber, as a reinforcing material, endows SMC with excellent electromagnetic shielding effect, making it suitable for electromagnetic protection applications.

(8) Ease of processing

Capable of flowing and filling into various complex geometric shapes, creating complex structures that cannot be achieved with traditional materials.

SMC (sheet molding compound) has a wide range of applications, covering multiple fields such as automotive industry, railway vehicles, electrical and communication engineering, construction engineering, medical field, shipbuilding field, aerospace field, military industry, etc. ‌

(1) Automotive industry: SMC's applications in the automotive industry include suspension components, front and rear bumpers, instrument panels, etc. In addition, it is also used for car bodies and body components, such as hard shell roofs, anti slip floors, flow barriers, sunshades, engine hoods, etc. In terms of components under the engine hood, SMC is used for air deflectors, intake duct covers, fan guide rings, engine sound insulation panels, etc. Interior decorative components such as door handles, dashboard, and steering rod components are also one of the applications of SMC.

(2) Railway vehicles: SMC's applications in railway vehicles include seats, coffee table tops, railway vehicle window frames, carriage wall panels and roof panels, railway signal transponders, etc.

(3) Electrical and Communication Engineering: The application of SMC in electrical and communication engineering includes electrical enclosures (such as electrical switch boxes, electrical distribution boxes, cable distribution box enclosures, terminal distributors), electronic engineering applications (such as antenna reflectors, radar covers, printed circuit boards), electrical components (such as insulators, insulation operating tools, motor commutators), communication equipment applications (such as telephone enclosures, cable distribution boxes, telephone booths), etc.

(4) Construction Engineering: The application of SMC in construction engineering includes high-rise roof water tanks, purification tanks, shower products (such as bathtubs, sinks, waterproof trays, toilets), building templates, storage room components (such as wall panels, ceilings, door frames), etc.

(5) Medical field: Manufacturing medical device casings.

(6) Shipbuilding industry: used for manufacturing ship hulls, cabins, engine components, etc.

(7) Aerospace: Manufacturing aircraft components such as wings, fuselage, tail fins, etc. It is also used to manufacture rocket engine casings, satellite structural components, etc.

(8) In the military industry, there is a demand for high-frequency and high-voltage applications such as radar and electronic countermeasures.

In addition, SMC is also applied in other fields such as containers, pole clamps, tool hammer and shovel handles, catering utensils, shelf pallets, etc.

Due to its plasticity, SMC can be formulated into any color and formula according to product requirements, with superior electrical and corrosion resistance properties. It is also lightweight and easy and flexible in engineering design, and its mechanical properties can be comparable to some metal materials. Therefore, it is widely used in multiple industries. ‌
