Title:
FOAM OF POLYOLEFIN-BASED RESIN
Document Type and Number:
Japanese Patent JP3692681
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain the subject foam useful for interior automotive trim, capable of simultaneously solving dimensional stability in molding and stain of bleed-out, by adding a specific compound oxide and/or aluminum oxide to a resin blend.
SOLUTION: This foam comprises (A) 100 pts.wt. of a blend of (i) 100-30wt.% of a polypropylene-based resin and (ii) 0-70wt.% of a polyethylene-based resin and (B) 0.1-20 pts.wt. of compound oxide particles (preferably kaolin) and/or aluminum oxide composed of aluminum having 0.02-20.0μm average particle diameter as a constituent component and has 0.200-0.025g/cm3 apparent density. Preferably the contents of silicon, aluminum and an alkali metal of the component B satisfy the equations 10%≤Si≤45%, 3%≤Al≤30% and 0%≤M≤20% (Si is a silicon atom content; Al is an aluminum atom content; M is an alkali metal content).
