Issue 3/2014 - Qingdao Refinery and Milliken develop polypropylene for thin-wall injection molding

Recently, Sinopec Qingdao Refining & Chemical Co.
, Ltd.
(hereinafter referred to as "Qingdao Refining") launched the use of Milliken & Company's Hyperform?HPN 20E nucleating agent for thin-wall injection molding special polypropylene resin PPH-MM45, PPH-MM50, PPH-MM60 series products, filling the gap in the domestic thin-wall injection molding special material market, aiming to better meet consumers' interest in affordable, ingredient safety, There is a growing demand for
transparent packaging products.

Qingdao Refinery and Milliken have been cooperating in the development of China's thin-wall injection molding materials since March 2013, and through research and discussion, the two parties decided to use Milliken Hyperform?HPN 20E high-efficiency polypropylene nucleating agent
.
Compared to comparable products on the market, Hyperform?HPN 20E nucleating agent enables faster and more stable processing, helping to increase productivity.
The consistent shrinkage of the product in all directions helps to reduce product deformation, so it can save significant energy consumption and processing costs for processing enterprises, thus bringing significant price advantages
.
In addition, the nucleating agent can be evenly distributed in high-melt finger high-flow polypropylene, which is advantageous for many thin-wall injection molding applications
.

The melting index of the thin-walled injection molding special polypropylene resin series products launched by Qingdao Refining is 45g/10 minutes ~ 60g/10 minutes, with high transparency, rapid prototyping, high rigidity and good impact resistance, reaching or even exceeding the performance
of imported similar brands.
In addition, these products also comply with SGS/FDA and other relevant domestic and foreign hygiene standards, suitable for the production of
high-speed thin-walled injection molding products (such as disposable lunch boxes, packaging boxes, etc.
) that come into contact with food.

At present, PPH-MM45, PPH-MM50, PPH-MM60 series products have been successfully tried by many enterprises in the industry, and the products show the characteristics of "high flow, high transparency, strong toughness, odorless", which is better than imported products year-on-year, and has been widely recognized
by users.
