Acrylic (ACRYLIC), also known as PMMA or ACRYLIC.
The chemical name is polymethyl methacrylate.
From the English Organic Glass, refers to PMMA board made of Organic compounds of MMA, its transparency and transmittance as Glass. Acrylic is an important thermoplastic which was developed earlier.
PMMA has the advantages of light weight, cheap price and easy molding. Its molding methods are casting, injection molding, mechanical processing, thermal molding, etc. Injection molding, in particular, can be mass production, simple manufacturing process, low cost.
Therefore, it is widely used in instrument parts, car lights, optical lenses, transparent pipes and so on.
Advantages and disadvantages of acrylic material
Acrylic is the best new material that can make sanitary ware after ceramic. Compared with traditional ceramic materials, acrylic in addition to unparalleled high brightness, there are the following advantages: good toughness, not easy to break.
Repair ability is strong, should dip in a bit of toothpaste with soft foam only can clean is provided to wipe a new; Soft texture, no cold cold feeling in winter; Colour is bright, can satisfy the individual character of different grade pursues.
Make stage basin, bathtub, sit implement with acrylic, not only design is exquisite, durable, and have environmental protection effect, its radiate line and the radiate degree of human body oneself skeleton differ almost.
Acrylic cleaning provides the earliest appearance in the United States, already occupied the whole international market 70% above.
Because acrylic production is difficult, high cost, so there are a lot of cheap quality substitutes on the market.These substitutes are also known as “acrylic”, in fact, ordinary organic board or composite board (also known as sandwich board).
Common organic board with ordinary plexiglass cracking material and pigment casting, surface hardness is low, easy to fade, with fine sand after polishing effect is poor. The composite plate has only a thin layer of acrylic on the surface and ABS plastic in the middle. It is easy to delaminate under the influence of thermal expansion and cold contraction in use. True or false acrylic can be identified from the fine color difference and polishing effect of the sheet section.
