PMMA Sheet Series

PMMA Material Introduction: PMMA, polymethyl methacrylate, commonly known as plexiglass, is a highly transparent, lightweight, easy-to-process, and weather-resistant thermoplastic widely used in construction, advertising, automotive, optics, and medical fields.

Production: PMMA production involves two main processes: raw material polymerization (to make sheets) and finished product processing.

1. Sheet Making: There are two main processes:

I. Casting Method: a. Batching and mixing b. Molding and sealing 3. Low-temperature prepolymerization 4. High-temperature curing 5. Cooling and demolding
II. Extrusion Method: a. Prepolymer granules b. Melt extrusion c. Calendering and shaping 4. Cutting and laminating

2. Finished Product Processing:

a. Cutting b. Trimming and grinding c. Hot bending d. Engraving/drilling e. Polishing f. Bonding and assembly g. Post-processing

Advantages:
I. Superior Light Transmission: 92% light transmittance, superior to ordinary glass, producing soft light without glare.
II. Lightweight and High Strength: Only half the density of glass, 7-18 times more impact-resistant than glass, producing no sharp fragments upon breakage. III. Weather-resistant and durable: Resistant to yellowing and aging with long-term outdoor use; resistant to weak acids and alkalis.

IV. Easy to process: Can be cut, drilled, hot-bent, laser-engraved, injection molded, and bonded; easy to dye/print.

V. Insulated and safe: Good electrical insulation; non-toxic. Some parts are suitable for medical use.
