What Is JD-211 PMMA and Its Key Applications

JD-211 PMMA (Polymethyl Methacrylate) is a high-quality transparent thermoplastic widely used for optical clarity, weather resistance, and impact resistance. It is an ideal choice for applications requiring lightweight, durable, and aesthetically appealing materials.

Composition and Properties

• Base Material: Polymethyl Methacrylate (PMMA)

• Additives: UV stabilizers, impact modifiers, colorants (optional)

• Processing Methods: Extrusion, injection molding, sheet casting, and thermoforming

JD-211 PMMA exhibits excellent optical clarity, high hardness, and good weathering resistance, making it suitable for both indoor and outdoor applications.

Key Features

• High Transparency: Light transmittance >90%, close to glass

• Weather & UV Resistance: Suitable for long-term outdoor exposure

• High Surface Hardness: Resistant to scratches and wear

• Lightweight: Easier to handle than glass

• Processable: Compatible with extrusion, molding, and thermoforming

• Chemical Resistance: Resistant to many acids, alkalis, and solvents

Applications

• Optical & Display Panels: Lenses, screens, and protective covers

• Construction & Architecture: Windows, skylights, and partitions

• Signage & Advertising: Lightboxes, signage, and display stands

• Automotive: Light covers, dashboards, and interior trims
