2. Plastic film - Wikipedia

   en.wikipedia.org/wiki/Plastic_film

   Almost all plastics can be formed into a thin film. Some of the primary ones are: Polyethylene – The most common plastic film is made of one of the varieties of polyethylene: low-density polyethylene, medium-density polyethylene, high-density polyethylene, or linear low-density polyethylene.

3. Die forming (plastics) - Wikipedia

   en.wikipedia.org/wiki/Die_Forming_(Plastics)

   For products such as plastic sheets or films, cooling is achieved by pulling through a set of cooling rolls (also known as calender or chill rolls), usually 3 or 4 in number. In sheet extrusion, these rolls not only deliver the necessary cooling but also help determine sheet thickness and surface texture (in case of structured rolls; i.e ...

4. Plastic extrusion - Wikipedia

   en.wikipedia.org/wiki/Plastic_extrusion

   A common post-extrusion process for plastic sheet stock is thermoforming, where the sheet is heated until soft (plastic), and formed via a mold into a new shape. When vacuum is used, this is often described as vacuum forming. Orientation (i.e. ability/ available density of the sheet to be drawn to the mold which can vary in depths from 1 to 36 ...

5. Visqueen - Wikipedia

   en.wikipedia.org/wiki/Visqueen

   Visqueen is a brand of polyethylene plastic sheeting (typically low-density polyethylene) produced by British Polythene Industries Limited.It is the registered trade mark of British Polythene Limited in numerous countries throughout the world.

6. Thermoforming - Wikipedia

   en.wikipedia.org/wiki/Thermoforming

   A sheet of hot plastic will be placed on top and the bed sealed, pulling the plastic down over the mold. In the most common method of high-volume, continuous thermoforming of thin-gauge products, plastic sheet is fed from a roll or from an extruder into a set of indexing chains that incorporate pins, or spikes, that pierce the sheet and ...

7. Poly(methyl methacrylate) - Wikipedia

   en.wikipedia.org/wiki/Poly(methyl_methacrylate)

   It is a transparent thermoplastic, used as an engineering plastic. PMMA is also known as acrylic, acrylic glass, as well as by the trade names and brands Crylux, Hesalite, Plexiglas, Acrylite, Lucite, and Perspex, among several others . This plastic is often used in sheet form as a lightweight or shatter-resistant alternative to glass. It can ...

8. Forming limit diagram - Wikipedia

   en.wikipedia.org/wiki/Forming_limit_diagram

   A forming limit diagram, also known as a forming limit curve, is used in sheet metal forming for predicting forming behavior of sheet metal. [1] [2] The diagram attempts to provide a graphical description of material failure tests, such as a punched dome test. In order to determine whether a given region has failed, a mechanical test is performed.

9. Vinyl siding - Wikipedia

   en.wikipedia.org/wiki/Vinyl_siding

   Vinyl siding is plastic exterior siding for houses and small apartment buildings, used for decoration and weatherproofing, imitating wood clapboard, batten board and batten or shakes, and used instead of other materials such as aluminum or fiber cement siding. It is an engineered product, manufactured primarily from polyvinyl chloride (PVC) resin.
