PP
● Overview
- Polypropylene (PP) has characteristics that are extremely similar to those of the HDPE that sometimes it is difficult to distinguish between the two. PP is often divided into the homo-PP and the co-PP. Although the PP density is extremely small (between 0.9 and 0.94), it is mechanically much stronger and harder than the HDPE, and has better electro-insulating properties. It is also highly chemical-resistant.
● Characteristic
▶ Low specific gravity (0.9 or lower), transparent, 95% crystalline
▶ Often used as a hard molding material
▶ Although it is shock-absorbent in room temperature, because it loses its strength against shock in temperatures below -5 degrees Celsius, it requires a grade that is highly shock-absorbent.
▶ Heat-resistant, wear-resistant
▶ Waterproof, chemical-resistant
▶ Smells like gasoline and loses stickiness and printability when combusted.
▶ Ages slowly under the sunlight and heat
▶ More affordable and light-weight than the HDPE
▶ Extremely light, insulates well, and easily workable using machines
▶ Can be welded or fused.
● Applications
▶ Plating, chemical tank lining, gears, poller guides
▶ Various ducts and storage tanks
▶ Electrolytic cell
▶ Structures and lining of fish breeding grounds
▶ Footholds and cutting boards
