Description
また芯材が中空または中実の形態を有する場合の全体寸法は特に制限されるものではなく、得られる一体押出成形体の用途に応じて適宜設定されればよい。なお、建築用部材としての剛性及び表面加飾性が求められることからすれば、前記厚みに加えて、芯材幅方向として20mm以上、好ましくは30mm以上の長さを有することが好ましい
溝3のピッチ(P)(すなわち、隣接する溝間における最深部間隔)は好ましくは0.03〜1.5mmであり、より好ましくは0.05〜1.0mmである。
ベース樹脂はポリオレフィン系樹脂である。ポリオレフィン系樹脂は1種類または2種類以上のα−オレフィンをモノマーとして含有する単独重合体または共重合体である。α−オレフィンは、例えば、エチレン、プロピレン、イソブチレン、ヘキセンのような炭素原子数2〜8、好ましくは2〜6のα−オレフィンが挙げられる。好ましいα−オレフィンは、エチレン、プロピレンである。ポリオレフィン系樹脂はモノマーとしてα−オレフィン以外の他のモノマーを含有してもよい。そのような他のモノマーとして、例えば、酢酸ビニル等のビニルエステル系モノマーが挙げられる。
MFRは190℃、荷重2.16kgfにおける値であり、JIS K 7210に基づき測定することができる。
