, are all focused on thermoforming.
Serial development of polypropylene and transparent polypropylene products
.
Where is the demand for transparent PP?
Where is the demand for transparent PP?Overseas epidemics are becoming more and more serious, and the global epidemic prevention and control ideas are not slack.
Residents in economically developed cities have increased demand for takeaways and disposable plastic lunch boxes
.
With the continuous improvement of the economic level, residents have higher requirements for the quality of life
.
Transparent polypropylene has been used in toys, packaging materials, medical machinery, industrial parts and other fields
.
Polyolefin enterprises are gradually reducing standard products and upgrading special materials faster than ever
.
700 yuan / ton higher than the price of general materials
700 yuan / ton higher than the price of general materialsIn terms of pricing, transparent material polypropylene is also significantly higher than ordinary injection molding and wire drawing materials, with an average price higher than 700 yuan/ton, and the price of some transparent material grades is 1500 yuan/ton higher
.
In terms of performance, transparent polypropylene has comparative advantages over other traditional transparent polymer materials, transparent PC and transparent PVC: simple process; good transparency and gloss; lower density; more balanced stiffness and impact strength; fully recyclable reuse
etc.
Which companies are supplying transparent PP?
Which companies are supplying transparent PP?Zhenhai Refinery adds new transparent PP products
Zhenhai Refinery adds new transparent PP productsOn July 16, the second polypropylene plant of Zhenhai Refinery successfully produced high-fluidity transparent polypropylene resin M50ET for the first time.
Copolymerized polypropylene resin, the new product is beneficial to downstream users to improve processing efficiency and save raw material consumption
.
Recently, under the organization of Sinopec Ningbo New Materials Research Institute, Zhenhai Refinery's polyolefin production, sales and research team has increased the pace of market research
.
The visit allowed the team not only to receive feedback from customers after using raw materials, but also to gain new market demands
.
The R&D team analyzed and judged the new market demand captured, and found that the application of high-fluidity transparent polypropylene is on the rise, while the domestic market is basically occupied by imported polypropylene
.
The R&D team responded quickly.
According to the technical characteristics of the polypropylene plant of Zhenhai Refinery, based on the original transparent polypropylene grades, a project was established to develop a series of products with higher flow properties
.
Zhenhai Refinery has many grades of transparent polypropylene.
According to the melt index, there are originally three grades of M19ET, M26ET and M35ET, which have a record of being exported to Japan
.
In addition to retaining the characteristics of high gloss and excellent transparency, the new M50ET product produced in this trial mainly has breakthroughs in flow performance and excellent processing performance, which can greatly reduce energy consumption and improve production efficiency
.
It is suitable for large parts, thin-walled products, household products and beverage packaging and other fields, especially in high-end fields such as milk tea cups
.
Next, Zhenhai Refinery will cooperate with target users to replace imported high-end polypropylene for trial use in milk tea cups, household items, etc.
, and carry out demonstration and application promotion, and the market prospect is good
.
What are the process technologies for the production of transparent PP?
What are the process technologies for the production of transparent PP?In terms of technology, transparent polypropylene mainly through antireflection modification of PP, so that the spherulites are extremely refined and homogenized, and the transparency, softening point, crystallization temperature and rigidity can be significantly improved
.
There are four main production processes: (1) using Z-N catalyst to directly produce random copolymerized transparent polypropylene; (2) using metallocene catalyst to directly produce transparent polypropylene; (3) adding nucleating agent to polypropylene resin Anti-reflection modification is carried out; (4) anti-reflection modification is carried out by blending method
.
The technology of domestic transparent agents is progressing, helping manufacturers to further optimize the production process, improve product performance, and develop more market applications
