PP Hollow Plastic Formwork Should Not Be Judged By Thickness Alone, Because Thickness Is Only An Appearance Dimension. The Real Quality Depends On Density, Hollow Structure, Formula, Production Process And Actual Reuse Performance.
1. Same Thickness, But Weight Can Be Very Different
PP Hollow Plastic Formwork Has A Hollow Structure, So The Same Thickness Does Not Mean The Same Material Usage. If Density, Foaming Degree, Hollow Rib Wall Thickness And Rib Arrangement Are Different, The Board Weight Will Also Be Different.
For Example, For The Same 1220×2440mm Size, A 15mm Thick Board May Weigh About 25kg From Some Factories, While Others May Be Heavier Or Lighter. The Same Difference Also Appears In 18mm Boards.
2. Density Decides Compressive Strength, Bending Resistance And Reuse Times
Construction Formwork Puts More Emphasis On Compressive Strength, Bending Resistance And Reuse Times.
If Density Is Too Low, The Board Becomes Soft, Compressive And Bending Strength Drop, And It Is Easy To Deform Or Break After Many Uses.
If Density Is Too High, The Board Becomes Too Heavy, Workers Find It Hard To Handle, Construction Efficiency Drops, And Labor And Transport Costs Rise.
With Reasonable Density, The Board Can Keep Good Load-Bearing Ability While Controlling Weight, So The Total Use Cost Is Lower.
3. Hollow Rib Structure Is More Important Than Simply Increasing Thickness
The Strength Of Hollow Plastic Formwork Does Not Only Come From "How Thick The Board Is", But Also Depends On:
Hollow Rib Wall Thickness
Rib Arrangement Density
Connection Strength Between Ribs And Board Surface
Whether Round Holes, Square Holes Or Other Optimized Structures Are Used
For The Same 15mm Thickness, A Board With Thicker Ribs And Denser Arrangement Usually Has Better Load-Bearing Capacity And More Reuse Times.
4. Formula And Process Directly Affect Stability
The Performance Of PP Hollow Formwork Is Also Affected By:
Whether New Material Or A Reasonable Ratio Of Recycled Material Is Used
Whether Anti-Aging And UV-Resistant Additives Are Added
Whether The Extrusion Process Is Stable
Whether Cooling And Setting Are Sufficient
Whether The Traction Speed Matches The Production Line
These Factors Decide Whether The Board Is Easy To Deform, Crack Or Lose Corners, And Whether It Can Be Reused More Than 50 Times.
5. Recommended Indicators When Choosing Boards
Do Not Only Ask "How Thick". You Can Check These Points:
Size: Such As 1220×2440mm, 915×1830mm
Thickness: 13mm, 15mm, 18mm, Etc.
Weight Per Sheet Or Density
Hollow Rib Structure
Reuse Times
Compressive And Bending Performance
Whether Recyclable
Application Scenarios: Walls, Floors, Beams, Columns, Bridges, Etc.
