Properties of polycarbonate films

Polycarbonate (PC) is an amorphous, crystal clear engineering thermoplastic which has many attractive mechanical and optical properties. For example, it has very high impact toughness and exceptional high light transmittance as well as good dimensional stability, creep resistance and elasticity over a wide temperature range. Because of its higher price relative to PVC, PE, and PP film, it is generally considered a specialty film.

Films made from PC are of high optical clarity, have excellent puncture resistance, and are heat sealable, but have low scratch and solvent resistance and tend to yellow when exposed to UV light for a prolonged time. Thus for more demanding applications, PC products have to be coated with a scratch and UV resistant layer for protection.

PC films allow for top-quality printing with standard inks using standard screen printing processes.

Unlike many other thermoplastics, polycarbonate can undergo large plastic deformations without cracking or breaking. Thus, it can not only be thermoformed but also processed and formed at room or slightly elevated temperatures using standard forming equipment.

Applications

Because of its outstanding optical clarity, good performance properties, excellent printability, and ease of processing, films made of polycarbonate are chosen for a wide variety of applications. It is generally a good choice for high quality film products such as ID and security cards, graphic film products, reflective panels, LED/LCD display windows, and automotive dashboard and interior applications. PC film is also a good choice for high quality (thermoformed) packaging. For example, PC film is used for sterile medical packaging that requires FDA approval as well as high puncture, chemical, and UV resistance. Therefore PC films has been used for many situations like OMAY PC Film, Road Traffic PC Film, Optical Electronic PC Film, Electronic and Electrical PC Film and Other Industries PC Film.

With PC materials, many products like meshes for filter are also invented.

Filtration meshes and filter elements for process water filtration

Industrial filter meshes and filters from GKD are used in many different process stages and applications in the field of water filtration. The spectrum of filtration ranges from coarse filtration of 1 mm right through to ultrafine filtration of 5 μm. The filtration mesh is selected on the basis of the respective mechanical requirements.

Benefits for process water filtration

Adapted filter media in the range from 9 μm to 5 mm

Individual manufacturing of filter elements for existing or new systems

Repairs of existing filters or corresponding spare parts

Filter screens for corrosive applications

Production of standard elements for OEMs

Screens for drum filters and inserts for filter baskets

Except for filter element mesh, there are many applications for a mesh, such as NBC mesh, fashion industry mesh, screen printing mesh, etc.

PET is among those plastics which are an important part of your everyday life. You find the polymer used in packaging, fabrics, films to molded parts for automotive, electronics and many more. For all the applications demanding lightweight and impact-resistant material, PET is of your choice. Also do not forget, PET is one of the most recycled thermoplastics as well.

Applications

PET sheet like transparent PET sheet and matt rigid plastic PET sheet are commonly manufactured into bearings, pump parts, components for frames, tank lids, insulators, friction strips and control discs. Primarily used in mechanical engineering, marine engineering, electrical and food and pharmaceutical applications. PET sheet is also manufactured into any kinds of packaging, commonly into food packaging, such as clamshell, egg tray, salad packaging, etc.

What is PETG?

Polyethylene terephthalate glycol, commonly known as PETG or PET-G, is a thermoplastic polyester that provides significant chemical resistance, durability, and excellent formability for manufacturing. PETG can be easily vacuumed and pressure-formed as well as heat-bent thanks to its low forming temperatures. This makes it exceptionally popular for consumer and commercial applications that involve 3D printing, or other heat-forming manufacturing techniques. Additionally, PETG is well-suited for fabrication techniques like die cutting, routing, and bending.

The Benefits of PETG Plastic

PETG is strong and cost-effective when compared to either acrylic or polycarbonate. Its unique characteristics make it preferable for impact-resistant glazing and high strength display units. Suitable for digital printing, PETG lends itself to product materials, displays, and signage. In general, PETG is a food-safe plastic that's commonly used for food containers and bottles for liquid beverages. Like acrylic and many other thermoplastics, PETG is fully recyclable.

PETG is both thermoformable and vacuum-formable, and can tolerate a tremendous amount of pressure without cracking. Although PETG is naturally clear, it takes color easily during processing. It can be injection molded into a variety of shapes, or extruded into sheets.

PETG's damage resistance is far higher than that of acrylic, to the point that it rivals the impact resistance of polycarbonate. However, PETG fabricates easily, making it an easy material for both practitioners and professional fabricators. Therefore it can be made into many products like PETG film roll, transparent rigid PETG sheet, matt rigid plastic PETG sheet, etc.

What's the Difference between PET and PETG?

Although these compounds look similar, they are fundamentally different materials on a molecular level. PET is the result of two monomers combining. PETG may involve these same monomers, but also includes glycol, giving it different chemical properties than PET. PETG is less brittle and more pliable than its PET counterpart, making it ideal for bottles. It also has better shock resistance and is better suited to higher temperatures.

Apart from these two materials, PVC is also a widely used plastic and it can be made into PVC Film Sheets, Pharmaceutical PVC Film, PVC Sheet, Transparent PVC Sheet and so on.
