Choosing the right plastic for your application can be confusing, especially if you are new to the industry. This time we'll focus on a material we've covered in more detail - polypropylene. If you can't tell from our other blog posts, you're bound to like PP later for a variety of reasons. PP is an economical material that offers a perfect combination of physical, chemical, thermal and sustainable properties.

This passage is going to talk about the followings of PP plastic sheet:

1) Introduction to PP plastic sheet

2) Characteristics or advantages of PP plastic sheet

3) Choose our best PP plastic sheet


1) Introduction to PP plastic sheet

PP plastic sheet comes in several different grades. One of the wonderful but confusing things about PP plastic sheet is that there are several different grades of the same polymer, and no two resins behave the same. While this may seem complicated, it is comforting to know that it gives the opportunity to tailor the formulation of the plastic sheet to the customer's exact application.

The three main grades of PP plastic sheet are homopolymer, random copolymer and impact (or block) copolymer. Homopolymer PP is the hardest of these three materials. Random copolymer PP resins contain ethylene, which provides higher impact strength and a softer feel than homopolymers. Similarly, block copolymer PP resin also contains ethylene, but at a higher content, resulting in a tough material with excellent impact strength even at low temperatures.


2) Characteristics or advantages of PP plastic sheet

PP plastic sheet is a semi-crystalline polymer, which means that the plastic exhibits ordered and tightly packed molecular chains. Regions of crystallinity, called spherical crystals, can vary in shape and size, and amorphous regions exist between regions of crystallinity. The semi-crystalline nature of PP plastic sheet gives it a hazy appearance in its natural state.

PP has the lightest weight of all polymers and is also the least dense polymer. This means that by making the switch, purchasers of PP sheet can experience a 30% increase in yield compared to polymers such as PET and PVC, resulting in more parts for the same amount of material. The increased polymer yield in turn means cost savings, and that cost goes right back to the bottom line. In addition, due to the lightweight nature of this plastic, this leads to a more sustainable solution by reducing solid waste by weight.

PP plastic sheet's PP also has good heat resistance, making it an ideal material choice for microwave or hot-fill applications. This is due to PP plastic sheet's high melting point - PP has an operating temperature range of up to 295°F and can be microwaved for hot fill temperatures up to 260°F. As a basis for comparison, HIPS has a maximum temperature of about 185°F and PET has a maximum temperature of about 160°F.

The semi-crystalline nature of PP produces a hazy appearance in its natural state. Using polypropylene sheets can now clarify this material.

Normally, PP crystallizes slowly, forming complex crystals that block the transmission of visible light, thus blurring the appearance. The addition of the clarifying agent introduces an additional location for crystal growth. As more crystals are filled in the same space, the crystals become smaller, allowing light transmission and enhanced clarity. As a result, you can now take advantage of all the wonderful properties inherent in the listed PP plastic sheet and still get the visual appeal that today's consumers want.


3) Choose our best PP plastic sheet
