How about the features of Polypropylene if suitable for transparent PP extruded products?
Polypropylene PP is a semi-crystalline polymer with good mechanical properties and is widely used. Among the many crystalline types of PP, Α-crystalline is the most common and stable crystalline one, but the large size of spherical crystals of this crystalline leads to the poor transparency performance of PP.
In addition, the tertiary carbon atoms in the chain structure of PP are more sensitive to oxygen and are easily oxidized to generate free radicals, and PP products are prone to yellowing when exposed to light or heat processing. These defects limit the wide application of PP in the field of transparent materials.
In addition, PP often needs to have excellent anti-aging properties when used as packaging materials to ensure the quality of products.
How to Improve the transparent of extruded PP plastic products?
Currently, the main method to improve the transparency of PP extruded profiles is to add nucleating agents. Highly active nucleating agents mainly include substituted aryl organophosphorus acids and sorbitol organic nucleating agents. Although there are many kinds of nucleating agents in the market, the main nucleating agents are permeation and enhancement. Modified PP with multiple additional properties is developed by H.D.Plasticsto to meet the increasing demand for transparent plastic extrusion products.
The Main PP extrusion plastic products used for a number of markets, including:
- Building & Construction
- Consumer Products
- Industrial Equipment
- Material Handling
- Health Care
