What's the full name of "PPC plastic pipe"?
Poly propylene carbonate, English propylene full name Poly carbonate, abbreviation PPC, also known as poly methyl ethylene carbonate, which is based on carbon dioxide and propylene oxide as an environment-friendly biodegradable plastic raw materials.
Can develop the following products: the preparation of polyurethane materials from aliphatic polycarbonate and isocyanate, better than ordinary polyester polyurethane hydrolysis resistance; using maleic anhydride as the third monomer of two three yuan copolymerization; product is a carbonate containing ester and ester of unsaturated resin, can be cured, can also composite with fiber like solid, is similar to the common unsaturated polyester is a kind of new material used; aliphatic polycarbonate with a variety of polymer blends and properties of different kinds of. Can be used as epoxy resin, PVC plastic toughening agent, plasticizer and additive; copolymer of carbon dioxide, ethylene oxide, carbon dioxide, three copolymer of propylene oxide and succinic anhydride can be completely microbial decomposition, no residue, biodegradable material is a class of promising.
Carbon dioxide copolymer with molecular chain flexibility, easy to adjust its performance by changing its chemical structure; prone to heat, under the action of catalyst or microbial decomposition, but also can be controlled by certain measures of oxygen and other gases have very low permeability.
PPC, commonly known as polycarbonate, is commonly known as bullet proof glue due to its superior mechanical properties. The utility model has the advantages of high mechanical strength, wide application temperature range, good electrical insulation performance (but no arc resistance performance), good dimensional stability, transparency, etc.. Widely used in electrical products, electrical and electronic products shell structures. PPC products are more modified, usually with glass fiber, mineral fillers, chemical flame retardants, and other plastics. The fluidity is poor and the processing temperature is high, so the processing of many grades of modified material requires a special plasticized injection structure.
Carbon dioxide copolymers exhibit excellent biocompatibility. The special design of the copolymer can be used as anticoagulant material or used as a drug delivery agent; surface treatment agent of some carbon dioxide copolymer can be used as a solid pigment or filler, the oxygen barrier material, surface active agent, ceramic adhesive, hot melt adhesive; poly propylene carbonate and nitrile rubber blends have good oil resistant heat oxygen aging property, have the mechanical properties than ordinary nitrile rubber better, is a kind of excellent oil resistant rubber.
