How to choose the right polypropylene grade for your applicationⅡ

Review to the last post

In previous post, we have discuseed the role the processing is in selecting the right polypropylene grade for your application. Homopolymer, random copolymer, impact copolymer, only 3 types, but numerous subtypes can be derived according the requirements.

Diverse products means tremendous kinds of processing ways and facilities, so the properties of polypropylene must can be learned well in processing progress, in order to supply people excellent products. Therefore, your equipment processing ability and product processing process are one of the important basis to help you choose the correct grade of polypropylene.

In addition to physical properties, chemical properties, and mechanical properties that allow products to achieve design performance and functional indicators, the aesthetic characteristics of products are also a very important standard. This is in line with the concept of people's pursuit of a better life. A beautiful flower, a beautiful girl, a handsome boy, and a cute-looking cat. The enjoyment of vision will bring a lot of happiness to Ran. Therefore, if your polypropylene products can bring people happiness visually, it will be a good thing for both manufacturers and users to be happy.

Let us understand the role of aesthetics in the selection of polypropylene materials.

What the role that aesthetics in selection of right polypropylene grade plays?

Polypropylene used in bulk and and retail food packaging where it helps to extend the shelf life and provide a high level food safety. Despite these characteristics, how to get a enjoyment of vision is also non-ignorable.

In fact, in many applications, especially packaging and household products, contact or transparency and clarity are very important product indicators. In these application scenarios, polypropylene product manufacturers can lock the raw material selection between homopolymers and block copolymers, of course, except for thin-walled parts and polypropylene film products, basically all products show a certain degree of transparency.Both homopolymer and random copolymer offer contact clarity during close contact between the object and the container wall.Only random copolymers provide perspective.The clarity can be improved with a nucleating agent called a clarifying agent.

In the actual wall thickness of most functional products made of block copolymers, most of them have a milky white and opaque appearance. Nevertheless, in some thin-walled products, such as cooked food barrels, candy boxes, etc., a certain degree of product contact transparency can be achieved.
