Classification of PVC foam board

PVC foam board (also commonly known as foam board, andy board) is a very practical lightweight board. Its classification dimensions are very many, mainly on the production process, pore structure and functional use. To make it clearer for you, PLUSWIN has organized the following several major classification methods for you

 1. Classification by production process and foaming structure (the most common classification) This is the core standard for distinguishing PVC foam boards which directly determines the surface texture and physical properties of the board. ·Free Foamed Board ·Other names: Common foam board, Sintra board. ·Features The melt expands freely after leaving the mold, with no dense hard skin on the surface, presenting a fine "rough" or uneven texture. It feels soft to the touch, has low density, and is relatively inexpensive. ·Application: Suitable for scenarios with low requirements for surface smoothness, such as advertising display boards, picture framing boards, carving, printing, packaging pads, etc.

·Celuka Foamed Board ·Alias: Celuka board. ·Features: Through special mold control, the surface of the board rapidly cooled to form a dense "skin layer". This makes the surface of the board very smooth, hard, wear-resistant, not easy to have scratches, and the mechanical properties are superior to free foaming boards. ·Application: Widely used in high-end fields such as furniture boards (cabinets, bathroom cabinets), exterior walls buildings, and interior decoration wall panels. ·Co-extruded Foamed Board ·Features: Different functional material layers (such as high weather resistance layer, decorative layer are combined together through co-extrusion technology. ·Application: It can achieve special colors, textures, or composite functions (such as fireproof, anti-ultra), and is often used in exterior walls of buildings and high-end interior decoration.

 2. Classification by Cell Structure and Physical Properties ·Open-cell Foam Board vs. Closed-cell Foam Board Open-cell Board: The internal bubbles are interconnected or partially interconnected, which provides better sound absorption. ·Closed-cell Board: The bubbles are not connected to each other which offers better waterproofing and moisture resistance, as well as superior insulation and heat preservation. ·Soft Foam Board vs. Rigid Foam Board ·Soft: Cont plasticizers, has a large expansion ratio, and is soft in texture, often used as insulation material. ·Rigid: Contains little or no plasticizer, has strength, a small expansion ratio, and is mainly used as structural material or decorative material in construction. ·Low-expansion Foam Board vs. High-expansion Foam Board·Based on different expansion ratios, it can be divided into low-expansion (<15 times) and high-expansion (>20 times). higher the expansion ratio, the lighter the board, and the better the insulation and soundproofing effect, but the strength will decrease relatively.

3. Classification by function and purpose To adapt to specific environmental requirements, PVC foam boards can also be subdivided as follows:·Fire-retardant foam board: With the addition of flame retardants, it meets building fire protection standards (such as B1 grade) and is suitable for public such as hospitals, subways, and shopping malls. ·UV-resistant foam board: With the addition of UV-resistant additives, it has strong weather resistance and is easy to fade, specifically used for outdoor billboards or exterior wall decoration. ·Environmentally friendly foam board: Using environmental-friendly additives, it meets EU RoHS,ACH, and other standards, used for children's furniture or export products. ·Coated/Aluminized foam board: With a surface coating of PVC film, PET, or aluminum foil, it enhances decoration and wear resistance, often used for overall cabinet doors, etc.

 Summary Comparison If you are making advertising words or simple carvings free foam board has the highest cost performance; if you are making cabinets or need to bear heavy furniture, skin-forming foam board is a better choice
