A new milestone in the history of polymer foam the first high-strength elastic foam with the advantages of styropor China, Shanghai - July 21, 2010 - since the invention of styropor (EPS: expandable polystyrene) in 1952, BASF has been writing successful chapters in the field of polymer foam: it has developed extruded polystyrene rigid foam board styrodur (XPS), high-strength elastic polyolefin series neopolen Upgraded version of melamine foam Basotect and EPS for thermal insulation. According to Jos bastiaens, European technology and innovation manager, BASF currently has a wealth of products and unique expertise in granule and extrusion foam. Through unremitting research and the listing of various new products, BASF has opened up new application fields in many industries. These industries include automobile and aviation, as well as solar energy, construction and, of course, packaging

now BASF has succeeded in another innovation: e-por based on new formula and new process. E-por is the first crack resistant foam that can be transported, stored, processed and recycled like traditional styropor materials, with high strength and elasticity. This material is characterized by its excellent surface weldability, excellent solvent corrosion resistance and attractive appearance. Plasma TV, notebook computer, refrigerator, washing machine and other high-quality electronic and electrical (e/e) products are sensitive to vibration. E-por has excellent crack resistance, so it can withstand multiple impacts. It is very suitable for the transportation and packaging of such products. With its special properties, this new particle from BASF can benefit the entire value chain of transportation packaging - from raw material processors, electrical appliance manufacturers and retailers to consumers

the anti-seismic requirements for the packaging of electronic and electrical products continue to increase. The weight of products uses about 12% of the total energy consumption of the national economy. The impact resistance is closely related to the safe transportation of electronic and electrical equipment. For strong and light goods, protective cardboard packaging is usually sufficient. However, paperboard can only absorb a small part of the energy, and the cushioning effect is limited, so it is usually used with styropor. Styropor is not only very light, but also has excellent cushioning performance. However, styropor is a kind of hard foam, which may break when items fall, such as unloading from a truck. Once the styropor breaks or tears, the cushioning performance will be greatly reduced

the weight of electronic products continues to decrease, but its internal structure is becoming more and more precise, and it is more and more sensitive to repeated impact, so the requirements for packaging become more stringent. This is why expensive and vibration sensitive products need to be packaged with polyolefin and copolymer foam that can withstand multiple impacts. However, compared with the standard packaging material styropor, these foam show some disadvantages in processing and cannot be easily recycled like styropor

e-por not only has the impact resistance and aesthetics of copolymer foam, but also has the recycling cost-effectiveness advantage of standard material styropor and the simplicity of processing. The content of e-por foaming agent is very low, less than 6%. The content of foaming agent in the competitive products with copolymer foam as raw material is more than 10%. These abundant foaming agents must be kept frozen in the raw materials, which means that the transportation and storage of copolymers must be completed in the cold chain. So far, competitive products with polyolefin as raw material cannot contain foaming agent, so they can only be pre foamed in the production process, that is, in the process of transporting products from raw material manufacturers to packaging material manufacturers, air occupies most of the space of transportation tools, resulting in a sharp rise in transportation costs

in contrast, e-por saves transportation, storage and energy costs. It can be transported and stored at room temperature. The packaging material manufacturer can foam it with the help of a small amount of steam. This material can be processed on traditional styropor machinery, which is more energy-saving than polyolefin processing. Most importantly, e-por is the only foam that uses styropor technology for degassing and recycling, and can withstand multiple shocks: this means that raw material processors do not need to replace their own equipment

contribution to the whole value chain

apart from raw material processors, e-por benefits the whole value chain, including consumers: electrical appliance manufacturers get a kind of dust-free flexible packaging material, which not only has attractive appearance, but also can reduce packaging volume, reduce damage and return, and reduce waste treatment costs. Retailers and consumers can handle this reliable transport packaging material like styropor, which not only has a cost-effective advantage, but also does not need to increase human and material resources

The successful development of e-por should be attributed to a new research method: BASF researchers no longer treat foam as a static mixture of polymer and foaming agent like copolymers; Instead, e-por was developed as a complex formulation containing multiple components. These components not only react with each other, but also with pentane blowing agent. Researchers successfully transplanted the modified concept of impact strength of polymeric materials to granular foam. This formula is produced by BASF's new process. Then, BASF's direct customers successively implement oven drying operators, that is, the raw material processors can use the traditional styropor technology to treat the particles and produce products with brand-new foam structure. BASF has piloted the supply of e-por in the market for nearly a year, and has carried out a series of customer projects in various regions of the world. At present, these projects are running successfully
