PLASTIC COLLAPSIBLE TUBES

EIRI Team — Sat, 25 Oct 2014 10:30:44 +0000

Plastic collapsible tubes are used for packaging of a range of products which were traditionally being packed in metal collapsible tubes, products which are normally packed in collapsible tubes are shampoos, cosmetics, toiletries, creams, lotions, floor polishes, shoe polishes, car cleaners, pigments, dye stuffs, artist colours, lubricants, printing or cyclostyling inks, food stuffs, mosquito repellents, vaccines, rubber solution etc. Collapsible tubes were initially introduced for packaging of artist's colour. However, finding its convenience for handling an dispensing its use has been extended for packaging of various other items.

CAST POLYPROPYLENE FILMS (CPP FILM)

EIRI Team — Tue, 21 Oct 2014 11:35:32 +0000

The term CPP is used in the plastics industry to describe polypropylene-based films produced by a cast extrusion process (Cast Polypropylene). Although there are some CPP films used for hygiene applications and synthetic paper (usually involving fillers and other additives), the term CPP is usually used to refer to high clarity films targeting lamination, metallization and packaging applications. The rapid quench achieved with chill rolls results in excellent film clarity and gloss.

These types of films differ from BOPP (Biaxially-Oriented Polypropylene) because they are not oriented. Orientation is a process that increases the tensile strength of film in a specific direction by stretching or rolling. Strictly speaking, CPP films experience a small amount of orientation, but only in the Machine Direction (MD), due to the nature of the process.

COLOUR MASTERBATCHES FOR VARIOUS PLASTICS

EIRI Team — Tue, 30 Sep 2014 08:09:10 +0000

As the name Suggests the predispersed colurs or colur concentrates contain a high ropertion (20 - 50% or even more) of pigment by weight uniformely dispersed in a suitable carrier resin. The carrier resin may be a lequid or solid. In the former case the product is a liquid dispersion while in the latter case the product is known as solid predispered colur. Liquid dispersions may be available as low viscosity materials for plastisols, or high viscosity pastes for themoplastics. Solid concentrates in the form of powders they are suitable for use in
powder resins. These concentrates are usually marketted for specific or a group of related plastics. Some so called universal dispersions are also available in the market.

RIGID PVC COMPOUNDED GRANULES FOR INJECTION MOULDING MACHINE (USED FOR PIPE FITTINGS, ELBOWS, SOCKETS, NUTS, ETC.),

EIRI Team — Thu, 25 Sep 2014 10:37:10 +0000

Indian plastics industry is one of the largest in the Asian Region. It had a modest beginning in the late twenties when articles like combs, soap boxes, ash trays etc. began to be manufactured in the country from imported raw materials. Three are about fifty materials identified as plastics and the list is being extended continously. Plastics are classified as thermoplastics and thermosets on the basic of the polymerisation method adopted to produce the basic plastic material as on the basic of the primary raw materials source. Polyvinyl chloride comes under thermoplastics. Polyvinyl chloride (PVC) polymers or resins are the most important constituents of PVC compounds and are classified into bulic or mass polymers, emulsion polymers, suspension polymers and paste-forming polymers. There is a fifth type known as solution polymers which is used for coating
applications.

PLASTIC INJECTION MOULDED ITEMS (like Buckets, Plastic Chairs, Bathing Tub)

EIRI Team — Sat, 20 Sep 2014 09:14:05 +0000

Plastic Injection Moulded Items have got tremendous demand now-a-days especially Plastic chairs, Buckets, Bathing Tubs etc.

Injection molding is somewhat unusual among production methods in that essentially the entire process in carried out on the injection molding machines were similar in general design to metal die casting machines, but the processing characteristics of plastic have led to change in design & evolution that are still going on. The product injection molded plastic furnitures are the products produced by these injection molding machines with varied shape & size along with different colour & shades according to the choice of customers & even according to the pattern as per the modern society such as office culture, drawing rooms of houses, which give style & likingness of consumers.

PLASTIC SHEET FROM SCRAP

EIRI Team — Fri, 19 Sep 2014 06:27:23 +0000

Acrylics (plastic) are known for their sparking crystal clarity and outstanding surface hardness. Together with superior weatherability and good chemical resistance, these characteristics have made them the material of choice for a wide range of applications. Acrylics can be cast into sheet form. Cast sheet is produced from methylmethacrylate, which is polymerised during casting. Acrylic sheet can be transparent, translucent or opaque. It may be abtained in various colours and shades. The outstanding characteristics of acrylic sheets are that it has optical clarity, good outdoor weathering characteristics, high strength to weight ratio, good dimensional stability etc.

PLASTIC DOORS (SINTEX TYPE)

EIRI Team — Thu, 18 Sep 2014 10:20:38 +0000

Plastic doors are an important aspect of any home improvement project. Front entry doors are the first thing that visitors to your home will see and you will want to make a good impression. One way to be sure of doing that is with Plastic doors. Plastic door has several advantages over a wooden door. There's no denying that a beautifully finished wooden door is appealing. The question is, how long will that wooden door retain its appeal? In many cases, you will have to replace or repair the wood within a few years, as wood is susceptible to weathering and
rotting. And it doesn't take long for that lovely glossy exterior to become a peeling eyesore. If you live in a listed building, you may have to choose timber doors and windows for your remodelling project.

PLASTIC WASTE RECYCLING UNIT & PYROLYSIS PLANT FROM PLASTIC & RUBBER WASTE (INTEGRATED UNIT)

EIRI Team — Wed, 17 Sep 2014 11:31:00 +0000

A plastic is any one of a large and varied group of materials which consists of an essential ingredient combinations of carbon with oxygen, hydrogen, nitrogen and other organic and inorganic elements. While solid in the finished state, at some stage in its manufacture it has been or can be formed into various shapes by flow-usually through the application singly or together of heat and pressure.
