본 발명은 난연성 및 내수성을 갖는 시스 조성물 및 이로부터 형성된 시스층을 갖는 케이블에 관한 것이다. 구체적으로, 본 발명은 케이블의 시스층에 있어서 서로 상충관계(trade-off)에 있는 난연성과 내수성을 동시에 향상시킬 뿐만 아니라, 내열성, 경도, 내마모성 등의 물성을 동시에 향상시키고, 외관을 향상시키고 제조비용을 절감시킬 수 있는 시스 조성물 및 이로부터 형성된 시스층을 갖는 케이블에 관한 것이다.
摘要:
A process to remove bad odours from plastic materials is disclosed, wherein said materials contain at least a polymer and at least a plasticiser. According to the process, natural or synthetic mono-, linear, branched or cyclic oligomeric carbohydrates are added during the compounding of the plastic formulation in order to fulfill the above indicated aim. The process is particularly suitable when said polymer is a polyvinyl chloride resin (PVC), chosen so as to exhibit a K value in the range K50-K85, and preferably in the range K64-K80. The invention also relates to a plastic material, containing at least a polymer and at least a plasticiser, on which natural or synthetic, mono-, linear, branched or cyclic oligomeric carbohydrates are grafted, once the formulation compounding already happened.

Embodiments herein include compositions, extruded articles, and methods of making the same. In an embodiment, an extruded article is included. The extruded article can include an extruded segment comprising a first composition. The first composition can include a polymer resin, particles and fibers. The fibers can be disposed within the first composition exhibiting a substantially non-aligned directional orientation. In an embodiment, an extruded article is included having a first portion comprising a first composition having a first fiber orientation and a second portion comprising a second composition having a second fiber orientation. The first composition can include a polymer resin and fibers. The second composition can include a polymer resin, particles and fibers. The fibers of the second composition can be oriented more randomly than the fibers of the first composition. Other embodiments are also included herein.
