What's the secret behind the popularity of PVC foam board?

With the rise of the green building materials trend, PVC foam board, with its excellent characteristics of light weight, high strength, malleability, and resistance, is rapidly expanding in multiple fields such as furniture, advertising, construction materials, packaging, and transportation. However, behind a high-performance PVC foam board, there is ahidden protagonist"—the foaming agent, which determines the board's density, strength, surface flatness, and even environmental grade.

Today, let's talk it from the source: the structure, classification, foaming principle of PVC foam board, and how to choose the foaming agent.

Why is PVC foam board so popular? PVC foam board, also known as Chevrolet board, is a lightweight board made by extruding and foamingvinyl chloride (PVC) resin as the main raw material, mixed with a certain proportion of foaming agent, stabilizer, lubricant, filler and other additives

Common classification Classification by foaming structure

1. Free Foamed Board ❖ Also known as ordinary foamed board ❖ Surface slightly coarse, light touch, and the foaming structure is relatively open ❖ Low density, low cost, suitable for non-structural uses such as advertising displays packaging cushioning

2. Celuka Foamed Board ❖ By controlling the rapid cooling of the surface through a specific mold, it forms a dense "skin layer" ❖ Surface smooth, high hardness, and better mechanical properties ❖ Widely used in high-end applications such as furniture boards, cabinets, bathroom cabinets, and decorative wall

3. Co-extruded Foamed Board ❖ Different functional layer materials are combined by co-extrusion (such as high weather resistance layer, decorative) ❖ Realize composite functions such as color, texture, fire resistance, and UV resistance ❖ Often used in exterior walls of buildings and high-end interior decoration

Classified by functional use

1. Fire-retardant foam board ❖ Add fire retardant to meet the fire protection standards interior decoration in buildings ❖ Suitable for public places such as hospitals, subways, shopping malls, etc.
2. UV-resistant foam board ❖ UV stabilizer to enhance outdoor weather resistance ❖ Suitable for outdoor billboards, exterior wall decoration boards
3. Coated/Aluminized foam board Surface coated with PVC film, PET film, or aluminum foil to improve decoration and wear resistance ❖ Widely used in integrated kitchen cabinets, bathroom cabinet back panels, door panels etc.
4.  Environmentally friendly foam board ❖ Use environmental-friendly additives or bio-based PVC, comply with EU RoHS, REACH, etc ❖ Used for export products or children's furniture with higher environmental requirements
