Light Guide Acrylic

    ZHEJIANG LONGYOU ZHANYU ACRYLIC CO., LTD., one of the leading acrylic manufacturers in China, is specialized in cast acrylic sheet production, research and exploiting. The company is located in Zhejiang Longyou economic developing zone with beautiful landscape around, which covers about 35,000 square meter.

• The Grades of PMMA
  PMMA can be classified into grades of GP (general purpose), HI (high impact), and OP (optical grade).
  
  
• Methyl Methacrylate and Specialty Methacrylates; MMA 
  MMA is the abbreviation of substance of methyl methacrylate, is a monomer for polymers.
  SpMAs is the abbreviation of substance methacrylates, specialty monomers for offering the polymer some unusual properties. For example: methacrylic acid, ethyl methacrylate, n-butyl methacrylate, i-butyl methacrylate, hydroxy methacrylate, ethylhexyl methacrylate. 
  
  
• The Application of MMA 
  MMA and SpMAs can be polymerized into polymers and copolymers, in forms of sheet, pellet, powder, solution, and latex. The middle product then can be processed into miscellaneous final products, such as: advertisement board, decorative panel, optical lense, optical fiber, paint, lacquer,adhesive, etc.
  
  
• The Characteristics of PMMA
  Very high transparent, Excellent weather resistance, Very good UV resistance
  
  
• The Production of PMMA
  PMMA sheet can be easily produced by cell cast or in a reactor and then a extruder. For example, when a PMMA sheet is produced by cell casting process, a syrup comprised of MMA and oligomer and polymer, was filled into the sealed cell, and then cured and post-cured following a pre-setted thermal procedure. 
  After cooling the cured sheet, the PMMA was obtained in sheet form. Another way to have a PMMA sheet is via the extrusion technique. PMMA pellet is conveyed into a extruder, then compounded, and pulled out in sheet form
  
  
• Definition of Monomer and Polymer
  A monomer is any substance that has low molecular weight and can be converted into a polymer. For example, methyl methacrylate (MMA) is a monomer that can be polymerized into poly(methyl methacrylate), PMMA.
  A polymer is any substance that has high-molecule-weight. For example, the PMMA formed from cell cast process has a molecular weight about 1000K, and which from extrusion has molecular weight less than 1000K.
