Why JD-205 PMMA Is Ideal for Optical and Industrial Applications

JD-205 PMMA (Polymethyl Methacrylate) is a high-quality transparent thermoplastic designed for clarity, durability, and weather resistance. It is widely used in optical components, signage, construction, and consumer products, providing a lightweight and aesthetically appealing alternative to glass.

Composition and Properties

• Base Material: Polymethyl Methacrylate (PMMA)

• Additives: UV stabilizers, impact modifiers, and optional colorants

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

JD-205 PMMA delivers high transparency, surface hardness, and dimensional stability, suitable for both indoor and outdoor applications.
