Plastic panel: Structure, advantages and disadvantages, classification and price 2025

Plastic panel is a material line designed with an insulation core (EPS, XPS or PU/PIR) and a PVC or fiberglass reinforced composite plastic surface. This is a construction material with a 3-layer structure: Outer shell (PVC or FRP composite), insulation core (EPS, XPS, PU/PIR) and protective bonding/coating layer. The product is 30-40% lighter than concrete, helping to reduce foundation load and reuse up to 70%.

This material has 6 advantages: Heat insulation, chemical resistance, light weight, health safety (no asbestos), antibacterial surface, easy to clean and flexible application. However, panel plastic has 3 limitations: Easy to scratch when impacted strongly, risk of toxic emissions if PVC plastic is handled incorrectly and difficult to process for sophisticated designs.

Plastic panels are classified into 3 components:

1. Insulation core: EPS (0,032 – 0,038 W/m·K, light, cheap), XPS (0,029 – 0,033 W/m·K, moisture resistance <0,5%), PU/PIR (0,018 – 0,022 W/m·K, fireproof, heat resistant).
2. Outer shell: PVC (light, cheap, anti-corrosion, heat resistant <70°C), FRP (hard, durable, chemical resistant, price 15-20% higher).
3. Surface Layer: PVC (reduces 70% risk of mold, lifespan 15 - 20 years), PP (impact resistant, chemical resistant, lifespan 20 years), PVDF (UV resistant, color retention 25 years).
   

Plastic panels are widely used in clean rooms, cold storage, food and seafood factories, chemical processing areas, and coastal projects. In terms of price, the product ranges from 430.000 - 900.000 VND/m² depending on the type: 50mm EPS core PVC (~430.000 VND/m²), 75mm XPS core PVC (~520.000 VND/m²), 75mm PU core PVC (~650.000 VND/m²), 100mm PU core PP (~750.000 VND/m²) and 100mm PU core PVDF (~900.000 VND/m²).

What is the structure of plastic panel?

With optimal design, the plastic panel has a 3-layer structure, ensuring outstanding performance in different environmental conditions:

1. Surface shell: The two outer layers of the plastic panel are usually made of PVC or fiberglass reinforced plastic (FRP).
2. Insulation and soundproof core layer: Is the core factor that determines the insulation and soundproofing properties of plastic panels. The core layer of plastic panels is usually made from EPS, XPS or PU/PIR foam.
3. Bonding layer and protective coating: The outer shell and insulation core are tightly bonded with specialized adhesives or heat-pressing technology. In addition, high-grade plastic panels are also supplemented with a surface protective coating (such as UV-resistant film or anti-corrosion paint) to increase their lifespan.

“The lightweight of plastic panels reduces foundation load by 40% compared to concrete, while allowing reuse of up to 70%, promoting sustainability and popularity in green projects in Vietnam.” – Architect Nguyen Thu Phong (2022).

Why are plastic panels widely used?

With the development of the trend of using sustainable materials, plastic panels have emerged thanks to the convergence of 6 advantages compared to traditional materials:

1. Good insulation: Plastic panels have excellent thermal insulation with low thermal conductivity, from 0.018 – 0.041 W/m·K depending on the core material. This helps save 30 – 50% of energy consumed for the cooling system.
2. Corrosion and chemical resistance: Thanks to the outer shell made of PVC or FRP composite, the panel has excellent corrosion resistance. This material can withstand salt spray test up to 2.000 hours (according to ASTM B117 standard).
3. Lightweight and convenient modular design: With light weight from 3,7 - 15,49 kg/m2 (depending on core layer) and modular design, construction time is shortened by 30 - 40% compared to traditional methods.
4. Health safety: Produced on modern production lines, does not contain asbestos or toxic substances, meets safety standards in living and working spaces.
5. Easy to clean and antibacterial: The smooth surface of the panel plastic has high antibacterial effect, preventing the growth of bacteria and mold.
6. Flexible application in many fields: Plastic panels meet a variety of needs from factories, cold storage, clean rooms to homes and offices.
   

What are the limitations of plastic panels that need to be noted?

When choosing plastic panels for construction projects, users need to clearly identify 3 limitations to have appropriate usage and storage plans:

1. Easily scratched and damaged by strong impact: Although it has a relatively high mechanical durability of 10 - 15 years, the surface of the plastic panel is still easily affected when exposed to sharp objects or large impacts.
2. Environmental impact: Some panels made from PVC plastic can generate emissions during processing or disposal if not done properly. Therefore, when the plastic panel reaches the end of its life, it needs to be collected and recycled properly.
3. Not suitable for elaborate, sophisticated designs: Since most panels are manufactured to standard sizes and have a rigid structure, bending and cutting are often difficult to perform.
   

How many types of plastic panels are there?

To meet the diverse needs in construction, plastic panels are classified into many product lines based on 3 components: Core layer, shell layer and shell surface coating. Each type brings its own advantages, suitable for each specific purpose of use.

Based on core layer

Plastic panels are divided into 3 main groups based on the core insulation material, each type has its own technical characteristics:

1. EPS core plastic panel: Using Expanded Polystyrene (EPS) foam beads as the core, this type of panel has the advantage of being light, easy to construct and low investment cost. The average thermal conductivity is about 0,032 - 0,038 W/mK, suitable for small factories, mini cold storage or civil works.
2. XPS core plastic panel: Made from Extruded Polystyrene (XPS), this panel line has a closed structure, good moisture resistance and waterproofing. Thermal conductivity is only about 0,029 - 0,033 W/mK, thereby improving heat retention efficiency, suitable for projects requiring high durability and tightness.
3. PU/PIR core plastic panel: This is a high-end line with Polyurethane (PU) or Polyisocyanurate (PIR) core.
