pmma acrylic plastic for transparent parts
Types of PMMA (acrylic)
There are different types of PMMA, each with unique properties and applications:

Polymethylmethacrylate (PMMA) : fresh datasetThe most common type, known for its optical clarity, impact resistance and weather resistance.
Poly(methyl methacrylate-co-methacrylate) (PMMA-MA): A copolymer with improved flexibility and toughness.
Poly(methyl methacrylate-co-ethyl acrylate) (PMMA-EA): Incorporates ethyl acrylate monomers for increased flexibility and impact resistance.
Poly(methyl methacrylate-butyl acrylate) (PMMA-BA): Combines PMMA with butyl acrylate monomers to improve flexibility, impact strength, and chemical resistance.
Impact Modified Acrylic: Blended with impact modifiers to improve strength while maintaining optical clarity.
UV Resistant Acrylic: Formulated to resist yellowing and degradation from UV exposure, it is suitable for exterior applications.
Extruded Acrylic: Produced by extrusion for uniform thickness and excellent optical properties.
Cast Acrylic : Made by casting acrylic resin into molds for superior optical clarity and surface finish.
Properties of PMMA (acrylic)
Physical properties of acrylic
Optical clarity It allows a light transmission of 92%, providing excellent transparency.
Refractive index Acrylic has a refractive index of 1.49, which ensures clear, undistorted vision.
Surface hardness It features high surface hardness, which enhances its durability and scratch resistance.
Scratch resistance Acrylic offers good scratch resistance, making it less prone to surface damage than other plastics.
Moisture absorption Acrylic has low moisture absorption, which ensures dimensional stability under various environmental conditions.
UV stability Acrylic maintains its properties under various environmental conditions due to its high UV stability.
Mechanical properties of PMMA
Mechanical property Description
Tensile strength It exhibits high tensile strength, making it suitable for various structural applications.
Solidity It exhibits moderate toughness, giving it sufficient durability for many applications requiring transparency.
Dimensional stability PMMA offers good dimensional stability, retaining its shape and size under different conditions.
Light Acrylic is significantly lighter than glass, making it easier to handle and install.
Shock resistance Its impact resistance is lower than that of polycarbonate, but it is still suitable for applications requiring transparency and durability.
