- Shape: Square, Rectangular.
- Color: Gray/White/Black.
- Material: High density PVC.
- Size (length, width and height): Customized.
- Application: Embedded materials for composite panels.
Description
The PVC square bar embedded in the composite panel is an excellent polymer material with heat resistance, corrosion resistance, waterproofing, heat insulation and high strength. It can not only increase the strength of the composite board, but also make up for the lack of nail-holding power of the honeycomb board and foam board. It is currently widely used in trucks and RVs.
What are the advantages of PVC square bars compared with wooden square bars?
- Waterproof and moistureproof: PVC material has natural waterproof performance, and will not deform, rot and other problems that are easy to occur on wood in a humid environment.
- High bending strength: PVC material has good rigidity.
- Lightweight: The density of PVC material is lighter than most wood.
- Thermal insulation: PVC material has low thermal conductivity, which can effectively reduce heat transfer.
- Service life: PVC materials are usually more than 10 years, but wood cannot do it.
