Polycarbonate Sheets

Polycarbonates (PC) are a group of thermoplastic polymers containing carbonate groups in their chemical structures. Polycarbonates used in engineering are strong, tough materials, and some grades are optically transparent. They are easily worked, molded, and thermoformed. Because of these properties, polycarbonates find many applications.

Polycarbonate is a durable material. Although it has high impact-resistance, it has low scratch-resistance.

The characteristics of polycarbonate compare to those of polymethyl methacrylate (PMMA, acrylic), but polycarbonate is stronger and will hold up longer to extreme temperature.

Polycarbonate has a glass transition temperature of about 147 °C (297 °F), so it softens gradually above this point and flows above about 155 °C (311 °F). Tools must be held at high temperatures, generally above 80 °C (176 °F) to make strain-free and stress-free products.

Unlike most thermoplastics, polycarbonate can undergo large plastic deformations without cracking or breaking. As a result, it can be processed and formed at room temperature using sheet metal techniques, such as bending on a brake. Even for sharp angle bends with a tight radius, heating may not be necessary. This makes it valuable in prototyping applications where transparent or electrically non-conductive parts are needed, which cannot be made from sheet.

PC Lite is the brand name for MG Polyplast Industries Pvt Ltd.

PC lite PC Compact Sheets as well as PC Rolls have high impact strength and are also high temperature resistant. Virtually unbreakable, and yet as transparent as glass with less than half its weight, Compact Sheets are easy to fabricate and install. Known for their excellent insulation properties, these sheets are suitable for cutting, drilling, bending, and thermoforming as well.

Lotus Compact Polycarbonate

Compact Polycarbonate offers an edge inExtreme clarity ensures excellent light transmission. Solid polycarbonate sheets with light transmission up to 90% compares favorably with glass. UV protection film aids in resistance against yellowing and loss of light transmission. many applications by virtue of its many salient virtues.

Solid structure gives higher impact strength than other plastic sheets or hollow polycarbonate sheets. Also being leak-proof, its impact strength is about 200 times as much as common glass, and about 10 times stronger than toughened glass.

Acrylic Sheets

Poly(methyl methacrylate) (PMMA) is the synthetic polymer derived from methyl methacrylate. It is used as an engineering plastic, and it is a transparent thermoplastic.

PMMA is also known as "Acrylic, Acrylic Glass"

This plastic is often used in sheet form as a lightweight or shatter-resistant alternative to glass.

PMMA AKA Acrylic is an economical alternative to polycarbonate (PC) when tensile strength, flexural strength, transparency, polishability, and UV tolerance are more important than impact strength, chemical resistance, and heat resistance. Additionally, PMMA does not contain the potentially harmful bisphenol-A subunits found in polycarbonate and is a far better choice for laser cutting It is often preferred because of its moderate properties, easy handling and processing, and low cost. Non-modified PMMA behaves in a brittle manner when under load, especially under an impact force, and is more prone to scratching than conventional inorganic glass, but modified PMMA is sometimes able to achieve high scratch and impact resistance.

PMMA is a strong, tough, and lightweight material. It has a density of 1.17–1.20 g/cm3, PMMA ignites at 460 °C (860 °F), PMMA transmits up to 92% of visible light (3 mm thickness), and gives a reflection of about 4% from each of its surfaces due to its refractive index (1.4905 at 589.3 nm).

Insulation Papers

Electrical insulation papers are paper types that are used as electrical insulation in many applications due to pure cellulose having outstanding electrical properties. Cellulose is a good insulator and is also polar, having a dielectric constant significantly greater than one.

Electrical paper products are classified by their thickness, with tissue considered papers less than 1.5 mils (0.0381 mm) thickness, and board considered more than 20 mils (0.750 mm) thickness.

The need for high voltage electrical transformers, there has been a need for an insulating material that could withstand the high electrical and physical stresses experienced around a core and windings. Pressboard, a board made by compressing layers of paper together and drying them, has been used for installation purposes in many of the first electrical machines.

By using Nomex® paper as electrical insulation, manufacturers of everything from transformers and generators to wind turbine systems and hybrid electric vehicles (HEV) have been able to help improve the integrity and performance of their own products.

Nomex® paper has played a key role in electrical insulation systems which are used in electrical equipment covered by applicable UL, IEC and country specific standards such as IEEE and JL.
