PP modified material, hence the name think Italy is some performance improvements, such as to impact resistance, stretch material on the basis of PP. Specific divided into the following categories. PP + calcium carbonate - this modification does not actually called modified, because adding calcium carbonate just Capacity of the physical properties of the material without any improvement, on the contrary lowers the toughness and strength of the material, but fortunately little fluidity of workability, add calcium carbonate is mainly to reduce costs.
PP + flame - reinforcing material flame resistance, mainly used in electrical accessories, instrumentation housing. PP + fiberglass GF- mainly to enhance heat resistance and rigidity of the material, reducing the size of the material shrinkage. Used for tool housings, auto parts and so on.
Modified PP method is also more common are filled with lime powder, glass fibers, and other plastic copolymer or a mixture, dyeing, adding nucleating agents, flame retardants and other additives, and so on. PP itself because of low prices, but also relatively easy modification, so the development of PP in this area is very wide, is nothing more than enhance the performance of the mechanical properties of PP, appearance, and so on all aspects of the fire-retardant properties.
