Merck develops Iriodin RMP for enhancing decorative rotational molded products

Innovative preparations are based on the classic Iriodin pigment

Merck is revolutionising rotational molding (rotomolding) for short. With Iriodin RMP, the innovative preparations based on classic Iriodin, the company is making something possible that was previously impossible: giving rotomolded plastic parts an attractive pearl luster effect. With four products initially, Merck is paving the way for creative plastics manufacturers and designers to capture additional markets for innovative products: hollow plastic bodies with brilliant colour effects.

Standard products with a focus on function have dominated the rotomolding markets until now: large-sized hollow bodies such as water tanks, trash containers, rain barrels and recycling bins. Attempts to enhance rotomolded products with decorative pearl luster effects have consistently failed. The particles did not blend with the basic polymer as desired, but were concentrated on the inside of the product or unevenly distributed. No two parts resembled each other.

With Iriodin RMP, Merck has succeeded in processing pearl luster pigments for rotomolding applications such that reliable results are achieved. The preparations can simply be incorporated into the polymer, without affecting the production time. The particles disperse evenly and give the entire end product its characteristic and fascinating pearl luster.

Four pigment preparations are being launched initially, with more expected to follow. Iriodin 119 WAY RMP (Polar White) captivates with its silver-white pearl luster effect and excellent resistance against weathering effects and yellowing. By contrast, Iriodin 6163 RMP (Icy White Shimmer) offers an even more intensive glitter effect combined with all the advantages of a synthetic substrate. Iriodin 305 RMP (Solar Gold) gives plastics a touch of luxury, while Iriodin 504 RMP (Red) makes red stylings possible.

The new series raises the procedure to new dimensions, thus capturing completely new markets. For the first time, Iriodin RMP allows designers to create decorative hollow bodies with impressive effects in the rotation process that unite form, function and attractive design. There are virtually no limits to the imagination with regard to potential new market segments for rotomolding: With Iriodin RMP, the design of flower pots or rain barrels, chairs or seat cubes, lamps, canoes or balls, buoys and floating docks can be imaginative, appealing and individualised.
