폴리프로필렌 천은 제법에 있어서 에너지 소비량이 가장 적고, 재생을 실시하는 경우에 융점이 낮고, 쉽게 재융해 할 수 있으며, 열분해 유화가 가능하고, 탄소와 수소만의 화합물임으로, 소각 시 유해 가스의 발생이 매우 적다는 특징이 있다. The polypropylene cloth has the lowest energy consumption in the manufacturing process, has a low melting point in regeneration, can be easily re-melted, pyrolyzed and emulsified, is a compound only of carbon and hydrogen, It is characterized by very few.

종래의 폴리프로필렌 천은 난연성 확보를 위하여 무기계 난연제인 수산화마그네슘을 적용하였으나, 수산화마그네슘의 경우 난연성이 부족함에 따라 동일한 난연 등급을 확보하기 위하여서는 기존의 할로겐계 난연제에 비하여 과량의 난연제가 첨가되어야 하므로 그에 따른 충격강도 등 물성 및 가공성의 저하를 피할 수 없는 문제점이 있었다.In the conventional polypropylene cloth, magnesium hydroxide, which is an inorganic flame retardant, is applied for the purpose of securing flame retardancy. However, since magnesium hydroxide is insufficient in flame retardancy, excessive flame retardant must be added in comparison with conventional halogen- Resulting in deterioration of physical properties such as impact strength and workability.
