Expanded plastics are found in all industries and it is essential that products meet the specific needs of each environment. Therefore, the material’s physical properties are important during the design. Do you know the difference between expanded polystyrene (EPS) and expanded polypropylene (EPP)?
Expanded Polystyrene (EPS) Properties
This lightweight material is easy to mold and cut. Therefore, it can be used in various products design. EPS is regularly found in packaging, insulation, large blocks, insulated containers, etc.
Expanded polystyrene has great insulation properties. This is why it is used in food industry for longer food preservation. It also serves a lot in the medical field: EPS can maintain the right temperature and thus ensure the medical supplies are optimal. On the other hand, this material is used to protect many objects during transportation, handling and storage. You will notice, when buying furniture, appliances or other items, that most of them are protected with EPS designed corners. It is also possible to find expanded polystyrene in insulation products. Indeed, different insulation products are manufactured to meet industrial, residential, commercial and institutional sectors requirements. They can be used in new constructions or during renovations. The use of these materials ensures a permanent insulating value, guarantees a better quality-price ratio, and facilitates installation.
Because it is versatile and its design possibilities are unlimited, EPS is everywhere around us. It is used in the most complex projects as well as under our roads.
Expanded Polypropylene Features
Expanded polypropylene is very similar to expanded polystyrene. However, it has a really useful feature for several fields: shape memory. Indeed, it is a major asset as it can keep its structure without breaking. Do you know where impact resistance is important? Just think about protective helmets, automotive components or electronic products packaging. This material is temperature-resistant while being shock absorbent, even if used at lower densities.
EPS, EPP and Recycling
These materials are composed of 98% air and 2% material. They are non-toxic and contain no CFCs or HCFCs. EPS and EPP are water and moisture resistant, meaning they will not contribute to mold growth. The most interesting aspect is that both materials are 100% recyclable and can be enhanced. Moreover, the enhanced material can be found in several places including stuffed products, large blocks, insulation products, etc.
Have you made your choice?
Are you using expanded plastics for your products design? Or would you like to innovate by incorporating them into your manufacturing process? Please note that it will be our pleasure to develop with you a greatly efficient, lightweight and environmentally friendly product.
