What is polypropylene carbonate used for?
Applications. Polypropylene carbonate is used to increase the toughness of some epoxy resins. It is used as a sacrificial binder in the ceramic industry, which decomposes and evaporates during sintering.
How is polypropylene carbonate made?
Polypropylene carbonate (PPC) is a thermoplastic polymer produced from the catalyzed copolymerization of carbon dioxide (CO2) and propylene oxide. The copolymer chain is composed of alternating segments of CO2 and propylene oxide, along with small amounts of propylene oxide homopolymer.
How is PPC plastic made?
Polypropylene carbonate (PPC), also called poly(propylene carbonate), is a polycarbonate plastic material, a copolymer of carbon dioxide and propylene oxide. It is made by reacting the monomers in presence of eg. a zinc glutarate catalyst.
Is polypropylene carbonate biodegradable?
Poly(propylene carbonate) (PPC) is a biodegradable aliphatic polyester.
Is propylene carbonate the same as propylene glycol?
Propylene carbonate (often abbreviated PC) is an organic compound with the formula C4H6O3. It is a cyclic carbonate ester derived from propylene glycol. This colorless and odorless liquid is useful as a polar, aprotic solvent. Propylene carbonate is chiral, but is used as the racemic mixture in most contexts.
What is polypropylene copolymer?
Polypropylene is an economical material that offers a combination of outstanding physical, mechanical, thermal, and electrical properties not found in any other thermoplastic.
How is polypropylene copolymer made?
Polypropylene Random Copolymer is produced by polymerizing together ethene and propene. It features Ethene units, usually up to 6% by mass, incorporated randomly in the polypropylene chains.
Is PPC same as PP?
Polypropylene copolymer (PPC) is a bit softer but have better impact strength, is tougher and more durable than homopolymer polypropylene. Copolymer polypropylene tends to have better stress crack resistance and low temperature toughness than homopolymer at the expense of quite small reductions in other properties.
Is propylene carbonate a hazmat?
Hazard statement: This material is NOT HAZARDOUS by OSHA Hazard Communication definition.
What is difference between PP and PPH?
Polypropylene copolymer and commonly abbreviated as PPC is tougher and more durable than PPH . Although polypropylene copolymer is softer, it offers better impact strength and tends to have better stress resistance and toughness even at low temperatures compared to Polypropylene homopolymer.
How do you make propylene carbonate?
They are mainly prepared by the carbonation of the epoxides (epoxypropane, or propylene oxide here): CH3CHCH2O + CO2 → CH3C2H3O2CO. The process is particularly attractive since the production of these epoxides consumes carbon dioxide. Thus this reaction is a good example of a green process.
