PC PMMA composite material is to use several extrusion screws to heat different kinds of resin into a multi-layer mold cavity at the same time, each layer of resin in the mold cavity or foreign exchange in proportion to form a whole, extrusion composite after polishing and cooling to become a composite plate or film.
PC PMMA composite board is generally divided into two-layer board and three-layer board, and the thickness of the two-layer board is 05mm-2mm, used for mobile phone covers, decorative parts, mobile phone protective covers, etc., three-layer boards are generally used in vehicle panels and other fields.
With the full popularization of 5G communication, wireless charging, NFC and other technologies, the market has put forward new requirements for mobile phone backplane materials.
PC PMMA composites overcome the problem of glass and ceramic materials being easy to fall and break by virtue of their own transparent glass-like effect performance, high plasticity, high hardness, and good scratch resistance. At the same time, after texture production, it can get a good streamer and dazzling glass effect, which can do a variety of beautification effects, silk screen printing logos, patterns, etc.; In addition, the development cycle of mobile phone back cover products produced by composite sheet is short, the single-line production capacity is high, the cost performance is high, and the cost is about 20-30% of the glass back cover, which is expected to become the mainstream mobile phone back sheet material for the public in the future.
PC PMMA composites also have a lot of room for substitution in automotive interior parts. PC PMMA composites mainly replace single engineering plastics in automobiles. According to the global sales of 79.4 million vehicles, the demand for 1 square film per vehicle, and the proportion of PC PMMA composite materials accounted for 30%, the demand for PC PMMA composite materials for automotive interior parts is about 23.82 million square meters.
It is foreseeable that with the promotion of 5G communication standards and the drive of terminal application innovation, the growth space of the PC PMMA composite board industry can be expected.
The main advantages of Dibo PC+PMMA composite board
In addition to the high strength, excellent transparency and optical properties of conventional PC+PMMA composite panels, compared with conventional products,Dibo PC+PMMA composite panel has better performance in elongation at break, indicating that it has higher toughness and bending resistance, and gives more creativity and possibility in product design. It can make the display cover and mobile phone backplane not confined to the two-dimensional plane, and can also be more explored to the Z-axis.
