When choosing a material for countertops, sinks, or other surfaces, solid surface is a popular option due to its durability and seamless design. However, not all solid surfaces are created equal. The two main types—pure acrylic solid surface (PMMA-based) and polyester resin-based solid surface—have significant differences in performance, safety, and longevity.
In this guide, we’ll break down the key distinctions between these materials and provide expert tips on selecting the best option for your needs.
When choosing a material for countertops, sinks, or other surfaces, solid surface is a popular option due to its durability and seamless design. However, not all solid surfaces are created equal. The two main types—pure acrylic solid surface (PMMA-based) and polyester resin-based solid surface—have significant differences in performance, safety, and longevity.
In this guide, we’ll break down the key distinctions between these materials and provide expert tips on selecting the best option for your needs.
Pure Acrylic (PMMA-Based): Made with polymethyl methacrylate (PMMA), this material offers superior impact resistance, flexibility, and stain resistance.
Ordinary Solid Surface (Resin-Based): Typically contains polyester resin + mineral fillers (e.g., calcium powder), making it more brittle and prone to cracking.
Why it matters: PMMA-based surfaces are non-porous, food-safe, and more hygienic, making them ideal for kitchens, hospitals, and high-end interiors.
| Feature | Pure Acrylic (PMMA) | Ordinary Resin-Based |
|---|---|---|
| Durability | High (flexible, impact-resistant) | Moderate (prone to chipping) |
| Stain Resistance | Excellent (non-porous) | Good (but may absorb stains over time) |
| Heat Resistance | Up to 180°C (356°F) | Lower (~120°C / 248°F) |
| Repairability | Can be sanded & polished | Difficult to restore once damaged |
| Eco-Friendliness | Zero VOC, food-grade | May contain styrene emissions |
Some manufacturers mix excessive calcium powder to cut costs, weakening the material. Here’s how to test:
Burn Test: Pure acrylic emits a faint, sweet smell (like candle wax), while resin-based surfaces release a strong, plastic-like odor.
Nitric Acid Test: Drop diluted nitric acid—low-quality resin surfaces may bubble or discolor.
For kitchens, hospitals, and luxury spaces: Pure acrylic (PMMA) is the best choice due to its hygienic, durable, and repairable properties.
For budget-friendly projects: Resin-based surfaces may work, but expect shorter lifespan and higher maintenance.
Our 100% PMMA-based solid surface is:
✅ FDA-compliant & food-safe
✅ Seamless & thermoformable (ideal for curved designs)
✅ Scratch & stain-resistant (easy to maintain)
