The foaming Characteristic resistance to flame resin constituent, and the resistance to flame resin foaming body and its production manner which use this

摘要

At the same time it is lightweight and although the resin foaming body which possesses the fire resistance which is superior is obtained the resistance to flame resin foaming body which becomes making use of the foaming Characteristic resistance to flame resin constituent which is suited, and this is offered. As for this invention, the weight average molecular weight 100,000 - 900,000 propylene resin 100 weight section, offers the foaming Characteristic resistance to flame resin constituent where the viscosity average molecular weight features the ethylene 1 butene copolymer 2 - 15 weight sections of 2,900 - 30,000, and that blowing agent is included. As for the resistance to flame resin foaming body which was formed making use of the foaming Characteristic resistance to flame resin constituent of this invention the fire resistance which is superior by the fact that ethylene 1 butene copolymer is used is granted, this as for the fire resistance which is superior making the thickness of the resistance to flame resin foaming body thin for lightening, to maintain, is possible. Choice figure It is not
