Thermosetting Acrylic Resin and Thermoplastic Acrylic Resin
  • 1. Chemical Structure

  • Thermosetting Acrylic Resin: usually a three-dimensional network structure formed by a cross-linking reaction. Once cured, it cannot be re-melted by heating or other methods.

  • Thermoplastic Acrylic Resin: composed of linear or low-crosslinked polymer chains, it can soften and flow when heated, and re-solidify after cooling.

  • 2. Processing Method

  • Thermosetting Acrylic Resin: usually processed by molding, pouring or coating, it will form a hard material after curing, which is suitable for applications requiring high strength and heat resistance.

  • Thermoplastic Acrylic Resin: can be processed by injection molding, extrusion and other methods, suitable for large-scale production and preparation of various shapes.

  • 3. Performance Characteristics

  • Thermosetting Acrylic Resin: has excellent chemical resistance, thermal stability and mechanical strength, and is widely use in coatings, composite materials and other fields.

  • Thermoplastic Acrylic Resin: easy to process and shape, but may not be as stable as thermosetting resin under high temperature and strong solvent environment.

  • 4. Recyclability

  • Thermosetting Acrylic Resin: once cured, it cannot be reoricessed or recycled, causing certain environmental problems.

  • Thermoplastic Acrylic Resin: can be remelted at high tmperatures, making them more attractive for recycling and reuse.

Main Production Equipments and Steps of Acrylic Resin
1. Raw Material Storage: Store raw materials such as acrylic monomers, initiators, and additives, usually equipped with storage tanks and metering systems.
2. Mixing System: Mixe various raw materials in proportion, and a high shear mixer can be used to ensure uniformity.
3. Polymerization Reactor: The polymerization reaction is carried out under controlled temperature and pressure conditions. Commonly used equipment includes stirred reactors and automatic control systems.
4. Cooling System: Cool the resin after the reaction for subsequent processing.
5. Filtration and Degassing: Remove unreacted monomers and impurities to ensure the purity of the product, usually using filters and vacuum degassing devices.
