The main business of Taihua plastics division is polystyrene (PS), ABS, ASA, San (styrene acrylic co polymer), polypropylene (PP), polycarbonate (PC) and so on Due to the active market expansion and the completion of the upstream raw material plants of Liuqing, the manufacturing and sales of PC / ABS and other comite adhesives have formed a strong integration between upstream and downstream. Looking forward to the future, the marketing of our products is expected to continue to grow. We hope that the company's products can provide reliable quality, stable material source and reasonable price of high-quality raw materials and technical support for China's plastic downstream processing industry, and jointly improve the overall situation To strive for the competitiveness of the industry.
聚的生产工艺主要经历了溶剂法、溶液法，液相本体法（含液相气相组合式）和气相法几个发展阶段。世界上用于生产聚的工艺方法按类别划分主要有以下几大类：溶剂法、溶液法，液相本体法（含液相气相组合式）和气相法
PP的化学稳定性优异，对大多数酸、碱、盐、氧化剂都显惰性。例如在100℃的浓、、40%酸及其它们的盐类溶液中都是稳定的，只有少数强氧化剂如等才可能使其出现变化。PP是非极性化合物，对极性溶剂十分稳定，如醇、、醛、酮和大多数羧酸都不会使其溶胀，但在部分非极性中容易溶解或溶胀
聚是加聚反应而成的聚合物，一种有机物。系白色蜡状材料，外观透明而轻。化学式为(C3H6)x，密度为0.89～0.91g/cm3， 易燃，熔点165℃，在155℃左右软化，使用温度范围为-30～140℃ 。在80℃以下能耐酸、碱、盐液及多种的腐蚀，能在高温和氧化作用解
PP力学性能 的拉伸强度和刚性都比较好，但冲击强度较差，特别是低温时耐冲击性差。此外，如果制品成型时存在取向或应力，冲击强度也会显著降低。虽然抗冲击强度差，但经过填充或增强等改性后，其机械性能在许多领域可与成本较高的工程塑料相竞争。PP 的表面硬度在五类通用塑料中属低等，仅比PE 好一些。当结晶度较高时，硬度也相应增加一些，但仍不及PVC、PS、ABS 等。热性质在通用塑料中，PP的耐热性是。PP 塑料制品可在100℃下长时间工作，在无外力作用时，PP制品被加热至150℃时也不会变形。
Taihua PP resin (tiripro? PP resin) adopts the CHISSO gas-phase process method of Japan, uses a new generation of high activity catalyst and strict quality management system, with an annual output of 510000 tons. It can produce homopolymer and copolymer, supply injection, extrusion, fiber, blowing, vacuum molding and other processing industries. It is widely used in household appliances, auto parts, food packaging, toys and people's livelihood products.
