NEW PC-BLENDS WITH EXCELLENT PROPERTIES

15.10.2020

ROMIRA, as a specialist supplier of engineering plastics and blends, is expanding its portfolio with two further products, which among other things show a very good performance in the area of UV resistance.

Pinneberg/Germany, October 15th, 2020 -  PC/PBT blend with particularly high impact strength, reduced warping tendency and increased UV stability: ROMILOY® EXP3008

PC/PBT blends are construction materials that combine the advantages of amorphous polycarbonate (PC) and crystalline polybutylene terephthalate (PBT). PC provides impact strength and dimensional stability, while PBT adds chemical resistance and stiffness to the blend.

The new blend, ROMILOY® EXP3008, is not only characterized by improved chemical resistance (towards fuels, fats / oils and many cleaning agents), high dimensional stability and UV resistance, but also by especially high impact strength and is therefore particularly suitable for demanding parts in outdoor applications.

Halogen free-flame retardant PC blends with exceptional mechanical properties and high UV stability: ROMILOY® 7410

Only flame-retardant plastics are permitted for use in many applications. Halogenated compounds are most commonly used as the main component for this purpose. The major disadvantages of these compounds include the highly toxic dioxins released in the event of fire, and, on account of the high concentrations required, there can be a deterioration of mechanical properties as well as migration of additives to the surface. Moreover, the synergist that is also necessary can catalyze various degradation reactions of the polymers.

ROMIRA has succeeded in adding a further product to its halogen-free PC blend portfolio by improving the formula and process: ROMILOY® 7410 is a rubber modified PC blend with a UL V0 listing at 1.5 mm. It features significantly improved mechanical properties, in particular notched impact strength, and high UV and temperature resistance. Optimized concentration of the modified flame-retardant package also prevents migration and the resulting reduction in surface quality.

These products can be used for both outdoor and indoor applications. Examples include the electrical and electronics industry, consumer goods and medical technology.
