Reasons And Solutions For Deformation Of PVC Foam Board
Dec 01, 2022
PVC foam board is a board with a closed-cell structure, so it is widely used. The main reasons for the deformation of PVC foam board are physical deformation and chemical deformation. Below, the editor will give you a detailed introduction:
Deformation due to physical causes:
1. Deformation due to high temperature during production
Solution: Targeted high-temperature resistant modification of plastic raw materials can solve such problems
2. Improper manufacturing leads to deformation. The physical properties of the plate raw materials cannot meet the actual requirements of the product.
Solution: reallocate the raw material formula to meet the actual requirements of the product.
3. Improper processing and storage methods lead to deformation. Such problems can be fundamentally solved
Deformation due to chemical causes:
The main reason is that the molecular structure of the raw material has changed.
The lower the density of the PVC foam board, the easier it is to deform. Due to its low density, it is easily deformed by heat or force.
Solution: Choose the product with the highest density possible according to the demand or choose PVC co-extrusion board
