Steel Materials
The main steel materials used for refrigerator’s exteriors and interiors are Pre-Coated Metal (PCM), Variable Coated Metal (VCM), printed steel, and stainless steel.
PCM is a pre-coated steel sheet. It is available in a variety of colors and textures and offers excellent corrosion and scratch resistance, making it the most widely used.
VCM is a laminated material made of a PVC film printed on steel. It offers excellent pattern expression and is ideal for luxurious designs (wood, metal, glass textures, etc.).
Printed steel is a method of directly printing and painting a steel sheet surface to create colors and patterns, allowing for a variety of exterior finishes at low cost.
Stainless steel is a high-quality material that is corrosion-resistant, durable, and offers a premium image. A brushed (hairline) finish for the product is often used.
Resins
Major resin materials used in refrigerators and home appliances include ABS, HIPS, GPPS, SAN, MDI, Polyol, and Cyclopentane.
American Bureau of Shipping (ABS) steel features excellent impact strength and processability, making it ideal for use in shipbuilding and exterior components (doors, handles). HOT Isostatic pressing (HIP) is used for interior liners, offering excellent impact resistance and formability. General Purpose Polystyrene (GPPS) is transparent and economical, but somewhat brittle, making it a preferred material for auxiliary applications.
Styrene Acrylonitrile (SAN) offers excellent transparency and heat resistance, making it suitable for see-through windows. Methylene Diphenyl Diisocyanate (MDI) and Polyol combine to form polyurethane foam, a key component in insulation. Cyclopentane is an eco-friendly foaming agent that provides excellent insulation properties.
