The main differences between PVC advertising board and KT board are material, durability, applicable scenarios, and price. Simply put, PVC board is harder and more durable, suitable for long-term or outdoor use; KT board is lighter and cheaper, suitable for short-term or indoor display. Here is a specific comparison:

1、 Material and physical properties

PVC board: made of polyvinyl chloride as raw material, internally foamed, with a smooth and hard surface, high density, heavy weight (about 3-4 times that of KT board), high hardness, corrosion resistance, fire resistance and flame retardancy (up to B1 level), and small size changes in humid environments.

KT board: foam board made of polystyrene, with foam structure inside, covered with thin paper or plastic on the surface, light in weight, soft in texture, easy to cut but easy to deform, not resistant to water and sun, and easy to collapse in wet environment.

2、 Processing and Applicable Scenarios

PVC board: suitable for machine carving and laser cutting, with high processing accuracy and good printing effect (high color saturation). It is commonly used for outdoor billboards, construction site signs, long-term cultural walls, background walls, workshop and factory signs, etc. It has good durability and is suitable for long-term use.

KT board: suitable for manual carving, mounting of images or stickers, simple processing but prone to debris, ink diffusion during printing, commonly used for indoor short-term advertising, display boards, supermarket personalized signage, model airplane production, ******* props, etc., suitable for temporary or low-cost needs.

3、 Durability and Cost

PVC board: Strong weather resistance, scratch resistance, long service life (up to 5 years or more), but the unit price is relatively high (about 30-80 yuan/square meter), and the long-term use cost is lower.

KT board: prone to aging, may turn yellow or shatter within 3-6 months, not resistant to outdoor environments, low unit price (about 5-20 yuan/㎡), suitable for short-term or budget limited projects.

4、 How to choose?

Choose PVC board: If used outdoors, for long-term display, requiring weather resistance or high-precision processing (such as laser engraving).

Choose KT board: If used indoors, for short-term displays, requiring lightweight or low-cost production.
