Acrylonitrile butadiene styrene (ABS) (chemical formula (C 8 H 8) x · (C 4 H 6) y · (C 3 H 3 N) z) is a common thermoplastic polymer. Its glass transition temperature is approximately 105 °C (221 °F). [4] ABS is amorphous and therefore has no true melting point. ABS is a terpolymer made by polymerizing styrene and acrylonitrile in the ...
A 2017 review indicated ways to avoid exposure to phthalates: [60] (1) eating a balanced diet to avoid ingesting too many endocrine disruptors from a single source, (2) eliminating canned or packaged food in order to limit ingestion of DEHP phthalates leached from plastics, and (3) eliminating use of any personal product such as moisturizer ...
Recycling codes on products. Recycling codes are used to identify the materials out of which the item is made, to facilitate easier recycling process.The presence on an item of a recycling code, a chasing arrows logo, or a resin code, is not an automatic indicator that a material is recyclable; it is an explanation of what the item is made of.
Crystalate is an early plastic. [78] Faturan is a phenolic resin, also similar to Bakelite, that turns red over time, regardless of its original color. [79] Galalith is an early plastic derived from milk products. [80] Micarta is an early composite insulating plate that used Bakelite as a binding agent.
Benzyl butyl phthalate (BBP) is an organic compound historically used a plasticizer, but which has now been largely phased out due to health concerns.It is a phthalate ester of containing benzyl alcohol, and n-butanol tail groups.
Acrylonitrile styrene acrylate (ASA), also called acrylic styrene acrylonitrile, is an amorphous thermoplastic developed as an alternative to acrylonitrile butadiene styrene (ABS), that has improved weather resistance. It is an acrylate rubber-modified styrene acrylonitrile copolymer.
