ABS/PMMA
Plastic sheet made of ABS / PMMA has many layers. It is created by the coextrusion of PMMA and ABS plastic (polymethyl methacrylate). Even at below-freezing temperatures, items with an ABS layer have a high level of impact resistance.
The top layer is made of impact-resistant PMMA, also known as "acrylic," which offers scratch resistance, defense against UV ray damage, excellent surface quality with a high gloss, resistance to acids, alkalis, fats, automotive fuels, antifreeze agents, detergents, and prevention of bacterial growth.
Because ABS/PMMA plastic sheet is easily thermoformed, it is feasible to produce a variety of goods and baths with intricate shape.
PMMA / ABS plastic may be painted well, enabling the production of sheets in a variety of colors. The sheet's bottom side has been corona treated (activated), and its high surface tension aids in improved adherence to adhesives and resins.
The low weight of ABS/PMMA sheets in comparison to both fiberglass and other similar materials is another extremely significant feature.

ABS / PMMA sheets
ABS / PMMA sheets The ABS/PMMA sheets are used for thermoforming as the usual forming temperature is from 130 to 140 °C. It is highly recommended to utilize an aluminum mold for thermoforming. Acrylic (PMMA) Capped ABS (Acrylonitrile Butadiene Styrene) is a co-extruded product consisting of a PMMA Capping Layer (5%) on a high-impact ABS. This product is known as PMMA/ABS Sheet. Storage: If an ABS/PMMA sheet is kept in damp circumstances for a long time, it should be ..
What are the key properties of ABS/PMMA sheets?
The ABS/PMMA sheets are known for their exceptional impact resistance, even in extreme temperatures. The top layer, made from PMMA (polymethyl methacrylate), provides excellent scratch resistance and protection against UV ray damage, while the underlying ABS (acrylonitrile butadiene styrene) adds durability and strength. This combination makes them suitable for a variety of demanding applications.
How does the coextrusion process affect the performance of ABS/PMMA sheets?
The coextrusion process allows for the combination of two different materials, namely PMMA and ABS, to create a composite sheet with enhanced properties. This results in a product that not only retains the high impact resistance of ABS but also gains the superior surface quality and weatherability provided by PMMA. Consequently, the sheets are highly durable and suitable for various industrial applications.
What are the recommended applications for ABS/PMMA sheets?
Given their unique properties, ABS/PMMA sheets are ideal for applications that require a combination of toughness and aesthetics. Common applications include display cases, signage, automotive parts, and protective covers, where both impact resistance and visual clarity are essential.
