Polypropylene (PP), a synthetic resin, first discovered in 1951, became commercially available six years later. Since then, it has been a stable material for those companies intent on producing plastic components. Producers in American states such as Minnesota commonly turn to one specific method to meet their demands. This is Polypropylene injection molding – ideal for producing parts for industrial and residential use.
Benefits
Manufacturers find the PP molding process is advantageous since it realizes to its fullest potential the benefits resulting from the properties inherent in this resin. The Polypropylene injection molding provides components reflecting the following characteristics:
- Durability: The material is tough and has an outstanding impact strength
- Versatility: Molding shapes the components into a variety of complex and simple shapes. In fact, PP when properly handled can adapt to any mold
- Low specific gravity
- Exceptional moisture resistance: Moisture does not penetrate but flows over
- High heat resistance: PP is able to withstand high temperatures making it perfect for certain components
- Mold in or “living hinge” capabilities: This is a critical requirement for many specialized or even common parts for diverse industries
- Good chemical resistance: Many industries have products that operate in harsh environments. PP is ideal for those where chemicals are a potentially destructive force
- Different grades: Molders can provide their customers with different grades of PP. this is particularly important for those in the food and medical industry where certain standards and specifications need to be met before parts and products are acceptable
What all invested parties also find favorable about PP is its low cost. This makes it extremely attractive to other alternative materials.
Polypropylene Injection Molding
PP, a popular synthetic, is currently responsible for a large percentage of manufactured components. It provides benefits for all the involved parties when the polypropylene injection molding processing condition. In Minnesota, companies tout PP’s ability to produce everything from simplistic toys to complex medical instruments.
