Polypropylene Black
PP is an easy to print general purpose low density Polypropylene. PP Chas been developed for its mechanical performance and superb layer adhesion. PP high stretch ability, decent flexibility and chemical/fatigue resistance makes it suitable for a variety of household articles and containers. PP can also be used for engineering articles such as living-hinges and snap-fit fastener materials. Lastly PP can be used to print dishwasher & microwave safe objects. PP is a cost-effective all round filament suitable for a broad variety of needs.

Features:
• High chemical & Fatique resistance
• High elongation before break
• Superb layer adhesion
• Suitable for food contact articles
• Dishwasher & Microwave safe
Additional info: PP does not adhere to any print sticker well enough to counteract warp on large objects, therefore we recommend a Polypropylene sheet (inexpensive) so that no heated bed is required. Adherence improves when the first layer temperature is higher. Printing with a raft improves bottom layer removal and evens out any rough/raised areas on the PP sheet or sellotape (see below). Polypropylene can be used on most common desktop FDM or FFF technology 3D printers. Storage: Cool and dry (15-25˚C) and away from UV light. This enhances the shelf life significantly.
Note: On advice from a customer PP can also be printed on Sellotape, obviously on the back and not on the sticky side!
Wikipedia
Polypropylene (PP), also known as polypropene, is a thermoplastic polymer used in a wide variety of applications. An addition polymer made from the monomer propylene, it can be produced in a variety of structures giving rise to applications including packaging and labeling, textiles, plastic parts and reusable containers of various types, laboratory equipment, automotive components, and medical devices. It is a white, mechanically rugged material, and is resistant to many chemical solvents, bases and acids.[1]
In 2013, the global market for polypropylene was about 55 million tonnes.[2] Polypropylene is the world's second-most widely produced synthetic plastic, after polyethylene.
