In premium interior design, two polymer finishes dominate: PETG (Polyethylene Chronology Glycol) and PMMA (Polymethyl Methacrylate) acrylic. While both offer glossy and matte options, they are chemically and structurally very different.
1. Chemical Composition & Optical Depth
PMMA acrylic (used in SurajWood ACRYLUX) is an optical-grade polymer with unmatched light transmission (92%). This gives high-gloss cabinets a deep, mirror-like clarity. PETG is a modified polyester plastic that has a slightly lower light reflectivity and can showcase a mild 'orange peel' waviness under close light.
2. UV Resistance & Yellowing
PMMA has inherently superior UV resistance. SurajWood offers a 10-year UV stability guarantee, ensuring that pristine white shutters stay perfectly white. PETG is more prone to organic degradation and will show mild yellowing or dullness within 3-5 years of high daylight exposure.
3. Surface Hardness & Repairability
All SurajWood PMMA sheets undergo a hardening process to reach 3H pencil scratch hardness. Cheaper PETG sheets typically have a 2H hardness, making them more prone to daily scuffs. Crucially, PMMA is buff-repairable, allowing micro-scratches to be easily buffed out using standard polishing compounds.
