How Can We Achieve Seamless Splicing Of PMMA Boards?
Jun 30, 2021
Acrylic, also known as PMMA or plexiglass, is derived from English acrylic (acrylic plastic), and its chemical name is polymethyl methacrylate. It is an important plastic polymer material that has been developed earlier. It has good transparency, chemical stability, weather resistance, easy dyeing, easy processing, and beautiful appearance. It has a wide range of applications in the construction industry. Plexiglass products can usually be divided into cast plates, extruded plates and molding compounds.
Acrylic characteristics:
1. It has crystal-like transparency, light transmittance above 92%, soft light, clear vision, and acrylic colored with dyes has a good color development effect.
2. Acrylic sheet has weather resistance, higher surface hardness and surface gloss, and better high temperature performance.
3. Acrylic sheet has good processing performance, which can be processed by thermoforming or mechanical processing.
4. Transparent acrylic sheet has a light transmittance comparable to glass, but the density is only half that of glass. In addition, it is not as fragile as glass, and even if it is broken, it will not form sharp fragments like glass.
5. The abrasion resistance of acrylic sheet is close to that of aluminum, and it has good stability and resistance to various chemicals.
6. Acrylic sheet has good printability and sprayability. The use of appropriate printing and spraying techniques can give acrylic products an ideal surface decoration effect.
7. Flammability: It is not spontaneously combustible but is flammable, and does not have self-extinguishing property.
Acrylic bonding and fixing characteristics:
1. It has excellent bonding strength to plastic, glass, metal and other materials
2. High light transmittance, fast deep curing, tough adhesive layer, vibration resistance and good stability
3. The glue has high viscosity, close to contact deformation and has certain fluidity, which is good for sizing
4. Good weather resistance, has passed the EU ROSH standard and SGS test
5. Good bending resistance, low shrinkage, excellent high and low temperature resistance
