Performance characteristics of polymer based sheet and film Flashcards
CH5
What is a polymer film and what is it used for?
It is a usually very soft and flexible material such as cellulose acetate used for photographic films
What is a polymer sheet?
It is thicker than a polymer film and is available in stock sheets of varying thicknesses
What is Foam Board and what is it used for?
Two outer layers of card with a foam middle core
- Used for mood board backing, presentation boards, modelling
What is Fluted PP Sheet and what is it used for?
Extruded sheet with integral “flutes” or corrugations. Lightweight and easily bent along the flutes
- Signs (such as sales boards for estate agents), storage box constructions, portfolio cases, small models
What is Translucent PP Sheet and what is it used for?
Tough polymer sheet. Can be folded millions of times. Virtually impossible to tear. Water resistant
- Packaging products, folder, boxes
What is Styrofoam and what is it used for?
Dense, closed-cell foam. Can be cut, shaped and sanded with standard workshop tools
- product modelling, formers for moulding and laminating
What is Low density polyethylene (LDPE) sheet and what is it used for?
Tough, available in thin sheet form, transparent, good chemical resistance, flexible
- Food wrapping, air pillow packaging, bubble wrap, carrier bag
What is Plastazote foam and what is it used for?
Closed cell polyehylene foam, tough, flexible, good impact resistance, impermeable to liquids
- Protective packaging, swimming floats, gym and exercise mats, sound and pipe insulation, stage props
What is CELLULOSE ACETATE and what is it used for?
Transparent, tough, naturally biodegrades
- Packaging film, membranes, photographic film
What is POLYLACTIDE and what is it used for?
Transparent, tough, naturally biodegrades
- Biodegradable packaging film
