Lembar plastik bermanfaat pp virgin untuk thermoforming

Polypropylene / PP is a polymer formed by the addition of propylene.White waxy material, transparent and light in appearance.The density is 0.89 ~ 0.91g/cm3, flammable, the melting point is 165℃, the softening is around 155℃, the operating temperature range is -30 ~ 140℃ .Under 80℃ can withstand acid, alkali, salt solution and a variety of organic solvents, can be decomposed under high temperature and oxidation.Polypropylene is widely used in clothing, blankets and other fiber products, medical equipment, cars, bicycles, parts, transport pipes, chemical containers and other production, also used in food, medicine packaging.

Resin polypropylene adalah salah satu dari empat resin termoplastik umum (polietilen, polivinil klorida, polypropylene, polystyrene). Proses produksi polypropylene terutama melewati beberapa tahap pengembangan metode pelarut, metode solusi, metode massal fase cair (dikombinasikan dengan fase cair dan fase gas) dan metode fase gas. Metode proses yang digunakan untuk menghasilkan polypropylene di dunia terutama dibagi menjadi kategori berikut: metode pelarut, metode solusi, metode fase cair (termasuk kombinasi fase cair) dan metode gas.

Lembaran polypropylene is mainly used in food packaging, household goods, automobiles, optical fiber and other fields in China.The biggest use of polypropylene in China is in woven bags, packaging bags, bundling rope and other products, accounting for about 30% of the total consumption.In recent years, with the development of polypropylene injection molding products and packaging film, the proportion of polypropylene used in weaving products has decreased, but it is still Area konsumsi polypropylene yang paling. Ini juga merupakan salah satu daerah dengan permintaan terbesar untuk lembar PP Polypropylene di masa depan. Area utama lainnya dari konsumsi domestik polypropylene adalah film, menyumbang sekitar 20% dari total konsumsi, terutama BOPP (proporsi dua kali lipat. According to the forecast of experts on the development of polypropylene industry, the demand for polypropylene sheet in China is likely to reach about 23.7 million tons by 2020.Textile products, injection products and film are still the main demand areas of polypropylene pp sheet in China, and the annual demand of pipe, plate, fiber and other fields is growing rapidly, the domestic demand for Lembar pp juga tumbuh dengan cepat. Film BOPP pemetaan kecepatan tinggi, pipa, non-anyaman tipis, wadah makanan transparan tinggi dan prospek pengembangan pasar bahan khusus lainnya bagus.
