다정점 분자량 분포를 갖는 폴리에틸렌 입자를 함유하는 중합체 조성물이 개시된다. 상기 중합체 조성물은 소결 공정을 통해 다공성 기판을 제조하는데 매우 적합하다. 본 발명에 따라 제조되는 제형은 증가된 굽힘 강도에 의해 나타나는 향상된 가요성을 갖는 한편 뛰어난 압력 강하 특징을 여전히 보유하는 다공성 기판으로 제조될 수 있다. Polymer compositions containing polyethylene particles having a multi-modal molecular weight distribution are disclosed. The polymer compositions are well suited to producing porous substrates through a sintering process. Formulations made according to the present disclosure can produce porous substrates having improved flexibility demonstrated by an increased flexural strength while still retaining excellent pressure drop characteristics.
