PMMA Acrylic Acid
时间：2024-08-26

PMMA (polymethyl methacrylate) is a transparent thermoplastic commonly referred to as organic glass or acrylic. It is generated by polymerization of methyl methacrylate (MMA) monomer. PMMA has many excellent properties, making it widely used in various industries.
characteristic
Transparency: PMMA has extremely high transparency, with a transmittance of over 92%, even more transparent than glass.
Weather resistance: PMMA has good resistance to ultraviolet (UV) radiation and is not easily yellowed or aged by sunlight exposure.
Mechanical strength: PMMA has high mechanical strength, is tougher than ordinary glass, and is not easily broken.
Chemical resistance: PMMA has good corrosion resistance to various chemicals, but is susceptible to corrosion by ketones and certain solvents.
Processing performance: PMMA is easy to process and can be formed through cutting, drilling, hot bending, and other methods.

Electrical Insulation: PMMA has good electrical insulation properties and is suitable for use in the electronic and electrical industry.

application

Architecture: PMMA is used to manufacture skylights, transparent curtain walls, bathtubs, shower rooms, etc.
Advertising: PMMA is used to make advertising supplies such as lightboxes, signs, display stands, etc.
Lighting: PMMA is used to manufacture lighting fixtures, lampshades, and other lighting equipment due to its transparency and weather resistance.
Electronic appliances: PMMA is used to manufacture panels and casings for electronic products such as televisions and computers.
Medical: PMMA is used to manufacture medical instruments, prosthetics, dental trays, etc.
Transportation: PMMA is used to manufacture windows and lighting fixtures for airplanes and cars due to its lightweight and high strength.
Production process
The production of PMMA usually adopts bulk polymerization, suspension polymerization, lotion polymerization and solution polymerization. Among them, bulk polymerization is the most commonly used method, which involves polymerizing MMA monomers under high temperature and pressure to produce PMMA resin.
Recycling and Environmental Protection
PMMA is a recyclable material, and the recycled PMMA can be used to manufacture recycled plastic products. The recycling of PMMA not only reduces environmental pollution, but also saves resources and energy.
