Solve the "stuck neck"! The new material high-melt refers to the mass production of polypropylene

Recently, the first joint workshop of Kazakhstan Petrochemical completed the production task of 1,000 tons of high-melt finger polypropylene new materials ahead of schedule, and successfully achieved mass production
.
The mass production of this new material solves the technical problem of "stuck neck" in China's high-end polypropylene production and fills the gap
of localization of high-melt polypropylene new materials.
At present, 6 grades of high-melt polypropylene products have been successfully trial-produced and successfully put on the market
.

High-melt polypropylene is a new material
for the production of high-end high value-added polypropylene such as 3D printing, precision injection molding, medical materials, and meltblown non-woven fabrics.
The flow properties and melting index of conventional polypropylene are relatively low, so the application range is limited
.
High melting refers to the better the processing fluidity and stability of polypropylene materials, the finer the fibers meltblown out, and the higher
the filterability of meltblown cloth and other products.

Liaoyang Petrochemical successfully trial-produced high-melt finger grade polypropylene products

On October 25, on the polypropylene production line in the polyolefin plant area of PetroChina Liaoyang Petrochemical Branch, high value-added brushed grade polypropylene special materials were being produced
.
Zhang Di, deputy director of the olefin operation department of Liaoyang Petrochemical Branch, said excitedly: "We have completed the 3,000 tons of high-melting finger homopolymer polypropylene LHA801U new product, which is a special material for thin-walled injection molding, which is widely used in the production of packaging boxes and lunch boxes, and has become a growth point
for new benefits of enterprises.
”

High melting finger homopolymer polypropylene LHA801U is the sixth grade of polypropylene new product successfully produced by Liaoyang Petrochemical, with good impact strength, high bending modulus, low warpage, is a thin-walled injection molding special material, with light weight, non-toxic, corrosion resistance, good fluidity, easy processing and molding, short product production cycle and other characteristics
.

Since 2022, Liaoyang Petrochemical Branch has continuously developed HP548R, HP565S, EP300M and other grades of polypropylene products
.

Jinneng Technology produced high-melt isotactic polypropylene for the first time

Recently, Jinneng Technology successfully produced a new grade of high-melt isotactic polypropylene HP648U for the first time, and the trial production achieved a success
.

The HP648U grade polypropylene produced this time is light blue, melting index is about 65g/10min, belongs to thin-walled injection products, mainly used in food containers, office supplies, toys, household items, etc.
, with excellent heat resistance, large tensile range, high temperature environment with good stability
