Daqing Refining & Chemical Company has successfully developed a new product of Gaogang injection polypropylene HA860R. After testing, the quality indicators of new products have met the requirements of qualified products.
Daqing Refining & Chemical 300,000 tons/year two sets of polypropylene plant adopts Spherizone production process with multi-zone circulating reactor as the core, and the products have excellent impact resistance, low temperature resistance and transparency. Since the device was put into production, it has successfully produced 9 grade polypropylene products such as transparent injection special material RP340N, hot and cold water pipe special material PA14D-2, high melting finger fiber material HP565S. In order to give full play to the technical advantages of the device and broaden the product field, Daqing Refinery Polypropylene Plant screened out five new products as the main direction of device development based on the market situation feedback from the sales company.
Gaogang injection polypropylene is one of the high-end products of polypropylene. Its gloss and heat resistance are greatly improved compared with ordinary injection products. It is widely used in home appliances and cars with high temperature resistance, tensile strength and high gloss. In the field of accessories and other fields, the market demand is large. Due to the high flexural modulus of the product, the extrusion system needs to add a variety of additives, which is very difficult to produce. At present, only Sinopec has the production capacity, but it has not yet formed a scale.
In order to trial-produce HA860R polypropylene products, the polypropylene plant has organized a new product development plan in advance, and with the assistance of foreign experts, the key parameters such as reactor temperature, density, reactivity, and hydrogen addition amount are strictly controlled. Trial production of high-injection polypropylene HA860R new products.
