Foam board, wall panels and rigid PVC foam
Blowing agent selection for PVC Foam Board.
Select a compound grade against the existing PVC formulation, current agent, process and board target—not ADC percentage alone.
Material context
What this application involves
Rigid PVC foam formulations used for foam board, wall panels, impact-resistant boards and related products.
Any candidate must be reviewed in the customer’s actual compound and operating conditions. HESO coordinates the supply-side discussion; the customer validates performance in production.
For PVC foam board, grade selection should follow the current formulation, process, board target and sample evaluation.
Common discussion points
What processors typically need to control.
Repeat product consistency
Cell structure
Surface quality
Processing compatibility
Board density control
Cost/performance balance
Buyer evaluation
Questions worth answering before a sample.
Use these questions to define the comparison method and sample brief before a trial.
- Q1
What board type and PVC formulation are currently used?
- Q2
What blowing-agent grade and dosage are currently used?
- Q3
Which surface, cell or density issue should the sample address?
- Q4
What sample quantity and destination are required?
Important selection principle
Higher ADC content does not automatically mean a better fit.
Compare the candidate against the current material, grade, dosage, process, target and cost/performance requirement. Confirm the result through a production trial.
