According to reports, two new kind of calcium stearate become rigid PVC) improve the window profiles, for packaging of polyolefin films surface quality best choice, their model is 500 and 600 type, change from the Ohio, United States Ferro company's organic specialty chemicals group development. These two types of calcium stearate not only maintain a acidic scavenging agents and lubricant function, and in applications can still improve product quality, make up products surface defect. In addition, by reducing the die head congestion and cause cleaning frequency, which can improve the production of polyolefin fiber. With the high cost of precipitation type products compare, these two calcium stearate products, products are apparently more economic powdery and granular 2 kinds. -- - China plastic information nets) can be developed plastic film discoloration

When you clean up the refrigerator, look at the wrapping paper color for changes can know whether it has metamorphic food. Want to know whether a counterfeit $on hand, just look at discoloration on without will do. This is a new type of soft plastic film two promising business applications.

According to reports, the new material is university of Southampton by Britain and Germany's darmstadt plastic institute jointly developed, it brings the natural and artificial optical effect together, is actually let objects accurately change color a new approach.

Researchers at the university of Southampton nussbaum berg and his colleagues developed accurate the artificial photonic crystal structure and natural photonic crystal structure of reflective effects together in plastic opals. This plastic opals film in 3d space stack up by the plastic pellets component in the middle also contains tiny plastic pellets of carbon nanoparticles, thus light not only on plastic pellets and the fringe area between surrounding material reflection, but also in filling in these plastic pellets of carbon nanoparticles surface between the scattering. This greatly deepened film color. As long as the volume control plastic pellets, you can generate only scattering some spectrum frequencies of light of the material.

Frage scientists solved scale production problems cooperation. Germany darmstadt plastic institute developed a applicable YuGuangZi crystal manufacturing procedures, mass production plastic opals films.

Nussbaum berger says this film ductility is very good, and color change in stretching, because when tensile this movement of lattice structure changed the composition of the distance between plastic pellets. This will make plastic opals film is used extensively, including the potential for food packaging and anti-counterfeiting recognition, even can be used for the defence domain.
