Polypropylene (PP) Injection Molding
Injection molding products are plastic products that everyone uses in their daily life. These products can be produced in various ways, but the most commonly used processing technique is injection molding.
Various plastic materials van be used to produce your end product. Whether you already know which plastic to use, or would like to make use of our expertise, we can produce your product with the best suited material. With several thousand plastics on the market, this choice can be tricky at times. The plastic material must fit seamlessly with the application of your product and the environment in which you will use the product. In addition to those choices, the cost of the plastic material is often also an important factor in the consideration of choosing a particular type of material. In general, (engineering) plastics have advanced mechanical properties that offer greater durability and are not compromised during the production process. Are you looking for a plastic that is relatively cheap, but still has a high impact resistance? Then polypropylene is the ideal plastic material for your end product.
Advantages of polypropylene (PP)
Polypropylene is the most common plastic material in the world after polyethylene (PE). Like PE, PP is also relatively cheap, but PP has a higher impact resistance than PE. In addition, the material has a high chemical resistance and does not absorb moisture. PP is therefore a plastic that is resistant to solvents, bases and acids.
Within polypropylene, a distinction can be made between homopolymer (PPH) and copolymer (PPC). A homopolymer is stiffer and stronger than a copolymer. The copolymer is softer, but on the other hand has a higher impact resistance. This makes it more resistant to stress and tougher at low temperatures.
Polypropylene (PP) and its uses
Because PP has a high temperature range and high impact resistance, the material has excellent mechanical properties. PP is therefore one of the most versatile thermal plastics and is extremely suitable for applications in technical constructions. By melting the polypropylene granules, we can convert them into various end applications, such as (film) hinges, measuring scoops, wheelie bins, medical pipette tubes and fastening clips.
Polypropylene (PP) Considerations
Are you considering opting for polypropylene? Then it is important to take the following factors into account:
- With thick-walled products, polypropylene can occasionally lead to sink marks;
- Polypropylene has poor UV stability, making it less suitable for outdoor applications;
- At (extremely) low temperatures, polypropylene becomes brittle. PP retains its shape at temperatures between -15 and 90 degrees Celsius.
