What is a Wood Plastic Composite Door?
The full name of this type of door is Wood Plastic Composite Door, abbreviated as WPC Door.
Wood Plastic Composite doors are manufactured from PVC plastic, recycled materials, calcium powder, and specialized additives. This mixture is blended in a standard ratio and extruded at high temperature and pressure to create a solid door blank, which is then processed, molded, and finished with a wood grain film.
For Wood Plastic Composite doors, the material is composed of:
- PVC Resin: The main base component, providing durability, water resistance, termite resistance, and shaping the product.
- Recycled Material: Helps optimize production costs, contributes to environmental protection, and still ensures the product's mechanical properties.
- Calcium Carbonate (CaCO₃): Increases hardness, dimensional stability, reduces shrinkage, and improves load-bearing capacity.
- Processing Aids (PE-WAX, Stearic Acid, ACR Processing Aids, CPE, Wood Powder...): Help materials disperse evenly, increase toughness, impact resistance, lubricate molds, and improve product surface quality. Very fine wood powder: Creates a natural wood feel, increases hardness and aesthetic appeal of WPC doors.
Why is it called a Wood Plastic Composite door?
If the main component is not wood, why is it called a Wood Plastic Composite door?
In fact, the word "wood" in the name is not used to describe the proportion of the material's components but to describe the usage characteristics and appearance of the product.
A modern WPC door has many characteristics similar to and can replace natural wood doors:
- New material that can replace natural wood, helping protect the environment
- The door material is as sturdy and solid as real wood
- Wood grain film surface with natural colors.
- Can be processed into many designs similar to wood doors.
- Non-toxic, safe, and environmentally friendly
- Completely reusable
In other words, consumers looking at the product will perceive the beauty and sturdiness of a wood door, while inside is a modern composite material that overcomes many disadvantages of natural wood, such as warping, termites, or water absorption.
That is also why the term "Wood Plastic Composite door" was coined and is widely used in the market.
Is more wood powder better for Composite doors?
What if the wood powder in the WPC composition accounts for a large percentage, such as 40-70% as some advertisements claim? If there is too much wood powder, it will be similar to industrial wood boards: susceptible to water absorption, swelling, decay, termites, warping, and flammability.
Wood powder is only a minor component within the group of technical additives, alongside many other substances such as heat stabilizers, impact modifiers, lubricants, and processing aids.
