PMMA acrylic sheets
PMMA is a transparent thermoplastic homo polymer, known as Plexiglas. This material is similar to polycarbonate used as a shock-resistant alternative to glass. It is especially suitable in cases where high impact resistance is not required. Plexiglas sheets were first produced in 1928 and marketed five years later by Rohm and Haas. In general, Plexiglas PMMA acrylic sheets are one of the most clear plastics on the market First uses of PMMA were in World War II, when it was used for submarine periscopes as well as aircraft windows, control towers, and canopies.
Some body who injured his eyes due to broken acrylic fragments were notable lower than injured hit by glass shards, so it’s better and safer substituted for glass.
Also please keep in mind that PMMA sheets are flammable, unlike polycarbonate.
Nowadays PMMA various applications develop , beside specifications as high transparency and impact resistance. Common uses include contact lenses, acrylic nails, paints, security barriers, medical devices, and LCD screens. Due to its sharpness. Due to its sharpness, it is often used in areas around exhibitions. Although they are commercially available in a variety of colors (clear and opaque), Plexiglas raw material enables light transmission same as glass capacity, makes it a great alternative. Acrylic is easily available and inexpensive. It is a good alternative to polycarbonate when material strength is not a deciding factor. Some bulletproof glass are made of this material.
What are the specifications of PMMA Acrylic sheets?
Thermoplastics melting point is an important feature of them (in PMMA 160 ° C) thermoplastics can be heated, cooled and reheated to significant melting without significant degradation and then recycled.
Why PMMA sheets are popular?
PMMA sheets are extremely useful plastics for applications require transparency while high impact resistance is not valuable. PMMA sheets scratch resistant compared to other transparent plastics is notable. It is a light weight and safety option to glassy and an economic alternative to poly carbonate in applications where strength is not an important factor. Using laser cutting technology, it can be cut into very delicate shapes because the material evaporates due to contact with the concentrated laser energy. If the optical resolution is extremely important, PMMA transparent sheets have many applications
How is PMMA acrylic sheets made?
Acrylics, like other plastics, processed by distilling hydrocarbon fuels into lighter groups, some of which combine with other catalysts to form plastics (typically through polymerization)
