PP is the abbreviation of Polypropylene, the Chinese name is polypropylene, commonly known as 100% plastic.
The copolymer type PP material has a low heat distortion temperature (100 ° C), low transparency, low gloss, low rigidity, but has stronger impact strength. The strength of PP increases with the increase of ethylene content. Due to the high degree of crystallinity, the surface stiffness and scratch resistance of this material are very good. The low MFR PP material has good impact resistance but low elongation. Acrylic is also called PMMA, which is polymethyl methacrylate. It is an important early development of thermoplastics with good transparency, chemical stability and weather resistance. Acrylic is the best new material that can be used to make sanitary ware after ceramics. Compared with traditional ceramic materials, acrylic In addition to unparalleled high brightness, it has the following advantages: good toughness, not easy to break; strong repairability. PP is the lightest plastic with a density of 0.9-0.91g/cm3, lighter than water, floating in the water. . PP pellets are milky white, translucent, waxy and easy to age. The ABS density is 1.06 g/cm3, which is slightly heavier than water. The pellets are yellow and are opaque plastic. ABS products have the comprehensive properties of “tough, hard and rigid”, high strength, good rigidity, hardness, impact resistance and good surface gloss of the products. The AS (SAN) density is 1.08 g/cm3, which is slightly heavier than water and close to ABS. AS is a micro blue, transparent pellet after PS modification. Acrylic (PMMA) pellets are mostly colorless and transparent (some are slightly blue) and have a density of about 1.20 g/cm3. The product has good transparency and is tougher and less brittle than PS.
