摘要:
Disclosed is a resin composition for improving a whitening resistance in bending deformation. The flame retardant polypropylene-based resin composition with an improved whitening resistance in bending deformation according to the present invention includes a polypropylene-based resin, a polyolefin elastomer, a modified polyolefin elastomer grafted with polar groups and an inorganic flame retardant, wherein the polypropylene-based resin is included at a content of 5 to 50 % by weight of the total composition, wherein the polyolefin elastomer is included at a content of 0.1 to 50 % by weight of the total composition, wherein the modified polyolefin elastomer grafted with polar groups is included at a content of 0.1 to 30 % by weight of the total composition, and wherein the inorganic flame retardant is included at a content of 30 to 75 % by weight of the total composition. The resin composition according to the present invention may be used as a coating material of electrical wires, and therefore may be useful to minimize a whitening phenomenon in bending deformation without deteriorated physical properties such as tensile strength, tensile elongation, etc.
摘要:
Disclosed is a polypropylene resin composition with flame retardance and abrasion resistance. The polypropylene resin composition according to the present invention includes 20 to 200 parts by weight of an inorganic flame retardant; and 0.1 to 10 parts by weight of at least one additive, based on 100 parts by weight of a base resin comprising 30 to 90% by weight of polypropylene copolymer resin and 10 to 70% by weight of polyolefin alpha copolymer resin. The polypropylene resin composition according to the present invention can be used for industrial cables with potent endurance since it includes an inorganic flame retardant to show flame retardance and it can remove or reduce a whitening phenomenon and show a significantly improved abrasion resistance without deteriorating moldability or mechanical property even when the contents of the composition are varied to enhance abrasion resistance.
