Acrylic sheet (ACRYLIC), a common name for special treatment of plexiglass. The research and development of acrylic sheets has a history of more than 100 years. The polymerization of acrylic acid was first discovered in 1872; the polymerizability of methacrylic acid was known in 1880; the synthesis of propylene polypropionate was completed in 1901; the industrial synthesis was attempted in 1927 by the above synthesis; the methyl acid ester industry in 1937 Manufacturing and development are successful, and thus enter into scale manufacturing. During the Second World War, the acrylic sheet had excellent toughness and light transmission. First, it was applied to the windshield of the aircraft and the sight glass of the tank driver's cab. The birth of the world's first acrylic bathtub in 1948 marked the beginning of a new milestone in the application of acrylic sheets.
Acrylic sheet cast sheet: high molecular weight, excellent stiffness, strength and excellent chemical resistance. This sheet is characterized by small batch processing, unmatched flexibility in color system and surface texture effects, and a full range of specifications for a variety of special applications.
Acrylic sheet extrusion sheet: Compared to the cast sheet, the extruded sheet has a lower molecular weight and a slightly weaker mechanical properties. However, this feature facilitates bending and thermoforming processes and facilitates rapid vacuum forming when handling larger sheets. At the same time, the thickness tolerance of the extruded sheet is smaller than that of the cast sheet. Since the extrusion plate is produced in large quantities and is inconvenient to adjust in color and specifications, the product specification diversity is limited.
