Sheets of ABS+PMMA consists of two layers. Bottom layer — resin plant resin (ABS) is the product of the copolymerization of Acrylonitrile, butadiene and styrene, that is a modification of high impact polystyrene.
The performance of the ABS is superior oops, having improved properties (including increased resistance to atmospheric and chemical effects) due to introduction into the polymer molecule fragments of Acrylonitrile. At the same time, the optimal combination of Acrylonitrile and butadiene units with fragments of styrene ABS provides the necessary elasticity and shock resistance, making it one of the most popular plastics for the production of complex molded parts with a high degree of stretch. The top layer is solid polymethylmethacrylate (PMMA, plexiglass) deposited on the base material ABS co-extrusion method.
The thickness of the PMMA layer depending on the purpose of the plastic is 5-10% of the thickness of the layer of the ABS. Coextruded PMMA-coating makes the surface of the material more rigid and solid, resistant to UV radiation and aggressive media. All these properties are characteristic of Plexiglas. In addition, the surface layer is easily given any desired color and surface texture without affecting the core layer of the ABS. This is important because it is the ABS when vacuumforming is responsible for the resistance of the final product and provides the necessary quality to carry out molding in the optimal mode. The field of application of the new material is very diverse due to the many variations of the thickness and color of the top layer of PMMA. In the advertising industry, the use of such plastics allows you to create a unique form of three-dimensional elements.
Features ABS/PMMA (acrylonitrile butadiene styrene /polymethylmethacrylate)
ABS sheets co-extruded with PMMA (used for sanitary ware) are multi-layer sheets with a top layer of impact resistant modified acryl. The bottom ABS layer ensures high-quality forming, good impact strength and low temperature resistance. The acryl layer guards against UV rays, provides an excellent surface aspect of strong gloss and chemical fastness (inertness). ABS/PMMA sheets can be made in various colors to suit specific customer requirements.
|Unit||Test method, ISO||Values|
|Tensile strength at break||%||527||18|
|Charpy unnotched impact strength||23°C||kJ/m2||179/1ep||15|
|Charpy unnotched impact strength||-30°C||kJ/m2||179/1ep||8|
|Charpy notch impact strength||23°C||kJ/m2||179/1epA||16|
|Charpy notch impact strength||-30°C||kJ/m2||179/1epA||5|
|Heat deflection temperature (HDT)||1.80 MPa||°C||75-2Ae||100|
|Vicat softening temperature||50H/50°C||°C||306/B50||97|
All above values apply to thermoplastics immediately after extrusion, with no aging effect.
ABS/PMMA plastic shows high scratch resistance and resistance to bacterial growth (good biocide properties). The acryl layer guards against UV rays, provides an excellent surface aspect of strong gloss and chemical fastness
under normal ambient conditions, the plastic sheet resists acids, alkalies, light and oxygen, it is also oil- and water-proof. The plastic easily dissolves in carboxylic acids, esters, incl. intrinsic monomers, ketones, chlorinated and aromatic hydrocarbons
ABS/PMMA sheets shows good insulation properties and high dielectric strength
ABS/PMMA can be subjected to all types of machining:
- all types of forming
- laser cutting, etc
SCOPE OF APPLICATION
plastics of ABS/PMMA compound are used for thermal forming of different sanitary products: baths, water basins, shower cabin modules, pans for showers, fountains, sauna elements, furniture and bathroom finishing. It is also good for refrigerator components, door & exterior trim in car building, can be helpful in production of outdoor advertising and retail/store equipment
