Where Light Meets Strength — The Alloy Engineered for Visible Excellence
Material Overview
PC/PMMA is the rare engineering plastic alloy designed not only to perform — but to be seen. By marrying polycarbonate’s impact resistance with PMMA’s optical clarity and surface hardness, this alloy delivers what neither base resin offers alone: a tough, scratch-resistant, deeply pigmentable material that holds its visual integrity through years of consumer handling.
The molecular structure of PMMA intensifies pigment depth and reflectivity, producing the ‘wet-look’ piano black and saturated color tones that define premium product aesthetics. Renhong’s PC/PMMA grades preserve up to 70% of polycarbonate’s impact strength while gaining PMMA’s surface hardness — a balance achievable only through precise compatibilization and dispersed-phase control during compounding.
Key Features
✨ High Optical Clarity
Light transmittance up to 88% in transparent grades; haze values below 3% achievable for translucent applications.
💎 Enhanced Scratch Resistance
Pencil hardness reaches 2H–3H — significantly higher than standard PC, often eliminating the need for hard-coat post-processing.
🎨 Rich Color Aesthetics
PMMA’s molecular structure intensifies pigment depth, delivering ‘wet-look’ piano black and saturated color finishes.
💪 Retained Impact Performance
Engineered formulations preserve up to 70% of polycarbonate’s impact strength while gaining PMMA’s hardness.
🌡️ Optical Stability at Temperature
Selected grades withstand HDT up to 100°C without warping or yellowing — suitable for instrument panel covers and lighting lenses.
