Plastic Additives on WPC (Wood Plastic Compounds) Application

Plastic additives are essential components in the production of Wood Plastic Composite (WPC) plastic floors. WPC plastic floors are a popular choice among homeowners and business owners due to their durability, easy maintenance, and resistance to moisture, insects, and rotting.

But what are plastic additives, and why are they important in the production of WPC plastic floors?

Plastic additives are substances added to plastic during the manufacturing process to enhance its properties. These substances can improve the plastic’s performance, such as its strength, flexibility, and durability.

In the production of WPC plastic floors, there are several types of plastic additives that manufacturers use to achieve desired properties. Let’s take a closer look at some of the most common plastic additives used in WPC plastic floor production.

Coupling agents Coupling agents are a type of plastic additive that is used to improve the bonding between the wood fibers and plastic matrix. Coupling agents have functional groups that can react with both the wood fibers and the plastic, resulting in a stronger bond between the two materials. This increased bonding strength can lead to better dimensional stability and mechanical properties of the WPC plastic floor.

Lubricants Lubricants are plastic additives that are used to reduce the friction between the plastic and the manufacturing equipment during production. They also improve the flow of the plastic during the extrusion process, resulting in a more uniform and consistent product. The use of lubricants can also reduce the amount of energy required during production, which can lead to cost savings.

UV stabilizers UV stabilizers are plastic additives that protect the WPC plastic floor from the damaging effects of UV radiation. These additives prevent the plastic from becoming brittle and discolored over time, which can affect its overall performance and appearance. UV stabilizers are especially important for WPC plastic floors that are exposed to direct sunlight for extended perio

EcoChem Products for WPC Application

As WPCs are considered cheaper alternatives for the building industry, light stabilizers need to guarantee the durability of the material with a reasonable overall cost position. EcoChem LS 770 is widely used in WPCs for its optimum cost/performance, with the possibility to be combined with a UV absorber such as EcoChem UV 531 to enhance UV protection. EcoChem LS 791 and UV P are alternative solutions. For bio-degradable WPCs based on PLA, EcoChem LS 622 is recommended in combination with UV P. EcoChem AO blends of AO 1010 and AO 168 such as B215 are commonly used to protect WPCs during processing, reducing both polymer viscosity variation and cellulosic decomposition.
