Solid Surface & Quartz Stone Since 2000 - GELANDY
In today’s highly competitive solid surface market, buyers often face the same challenge:
⚪The prices look quite different — are the materials really the same?
In reality, Pure Acrylic, Modified Acrylic, UP (Polyester), and Calcium Powder material differ significantly in cost structure. Some low-priced products reduce costs by increasing filler content, often at the expense of performance, durability, and long-term value.5 practical, industry-recognized methods to help you quickly identify the real material behind a solid surface sheet.
1. Check the Price Range First: Extremely Low Prices Usually Mean High Filler Content
General industry positioning:
✔Pure Acrylic Solid Surface → Premium price range
✔Modified Acrylic → Mid-to-high range
✔UP / Polyester → Mid-to-low range
✔Calcium Powder Board → Lowest price tier
If a product is priced significantly below the market average while being advertised as “pure acrylic,” it deserves closer verification.
2. Inspect the Cross-Section
Whenever possible, look at a cut edge or sample piece.
✔Pure Acrylic
Dense and refined structure
Almost no powdery appearance
✔Modified
Slight particle visibility
✔UP
Coarser particles
✔Calcium Powder Sheet
Strong powder-like texture
Edges may chip easily
3.Observe the Cutting Dust — A Method Many Professionals Use
This is a widely trusted technique in the industry, yet many new buyers overlook it.
When the sheet is cut using a saw or CNC machine, pay close attention to the debris produced.
✔ Pure Acrylic
Produces more curls or shavings rather than fine dust
Slightly flexible to the touch
Does not disperse like flour
✔ Modified Acrylic
A mix of shavings and powder
Moderate dust level
✔ UP / Calcium Powder Boards
Very fine dust
Similar to talcum powder
Easily becomes airborne
4.Notice the Smell During Fabrication
✔ When sanding or cutting:
Pure Acrylic → Mild odor
Polyester / Calcium-heavy boards → Sharper, more irritating smell
✔ A strong odor often suggests:
Lower-grade resin
Higher VOC levels
Potentially weaker environmental performance.
5.Evaluate Material Transparency from the Supplier
✔Reliable suppliers are typically willing to provide:
SGS or CE test reports
Fire resistance ratings
Environmental certifications
Material composition details
✔If a supplier avoids discussing the material and focuses only on price, consider it a warning sign.
