Compressed board is generally more expensive than acrylic. This is due to several factors, including the materials used, manufacturing processes, and the intended applications.

Compressed board, also known as particleboard or medium-density fiberboard (MDF), is made from wood fibers compressed together with resin. The process involves breaking down wood chips into small pieces, adding a resin binder, and then pressing them into a board. This material is widely used in construction, furniture making, and cabinetry due to its strength, versatility, and cost-effectiveness. However, the cost of compressed board can vary significantly depending on the quality and brand. High-quality compressed board with better finishes and denser construction can be more expensive than acrylic.

Acrylic, on the other hand, is a type of plastic made from polymethyl methacrylate (PMMA). It is known for its transparency, durability, and resistance to weather and chemicals. Acrylic is used in various applications, including windows, aquariums, and decorative items. The cost of acrylic is influenced by factors such as thickness, color, and the presence of any additives or treatments. Generally, acrylic is more expensive than compressed board due to its superior properties and the more complex manufacturing process.

According to a report by Grand View Research, the global acrylic market size was valued at USD 8.3 billion in 2020 and is expected to grow at a CAGR of 5.2% from 2021 to 2028. This growth is attributed to the increasing demand for acrylic in the construction, automotive, and healthcare industries. In contrast, the global particleboard market size was valued at USD 21.6 billion in 2019 and is expected to grow at a CAGR of 4.5% from 2019 to 2025, according to a report by MarketsandMarkets. The higher market value of acrylic compared to particleboard reflects its higher price point.

In summary, acrylic is generally more expensive than compressed board due to its superior properties and more complex manufacturing process. While compressed board is a cost-effective material for many applications, acrylic's unique characteristics make it a premium choice for specific uses where its properties are essential.
