polymethyl methacrylate modified - Names and Identifiers
polymethyl methacrylate modified - Introduction
Modified polymethyl methacrylate (modified PMMA) is a polymer material obtained by changing the chemical or physical properties of polymethyl methacrylate (PMMA). The following is a description of the nature, use, preparation and safety information of the modified PMMA:
1. Nature:
modified PMMA has the following main properties:
-Excellent transparency and optical properties, similar to glass;
-Good heat resistance, can withstand temperatures up to 100 ℃;
-superior mechanical properties, high strength and rigidity;
-good resistance to chemical corrosion, not easy to be acid, alkali and solvent erosion;
-Enzymatic hydrolysis performance is good, is conducive to environmental friendly biodegradable.
2. Use:
Modified PMMA is widely used in the following fields:
-optical field: used in the manufacture of transparent optical components, glasses, display, lights, etc;
-Medical field: used in the manufacture of artificial organs, medical equipment and dental materials;
-Construction field: used to make heat-insulating windows, ceilings, lighting ceilings, etc;
-Automotive industry: used in the manufacture of car windows, lampshades, etc.
3. Preparation method:
The preparation methods of modified PMMA mainly include the following:
-toughening agent modification: by adding polymer toughening agent (such as acrylonitrile copolymer, carbon nanotubes, etc.), improve the impact resistance of PMMA;
-anti-ultraviolet modification: improve the weather resistance of PMMA material by adding anti-ultraviolet agent;
-flame retardant modification: by adding flame retardant, improve the flame retardant properties of PMMA materials.
4. Safety Information:
Modified PMMA is relatively safe under normal use conditions, but the following matters still need to be paid attention:
-avoid contact with strong oxidant, ammonia and other strong corrosive substances, so as not to cause dangerous reaction;
-Avoid prolonged exposure to high temperature to avoid decomposition and harmful gases;
-Personal protective equipment such as protective gloves, goggles and face shields should be worn during operation to avoid direct contact with the substance.
