Process and apparatus for preparing granulates

Multilayered, flat shaped part with a visible side and a support layer

For the production of sandwich structure elements comprising non-cellular polyurethane layers and polyurethane foamed layers which are produced on a substrate by the application of layers to a substrate, it is proposed that at least the non-cellular polyurethane layers contain 15 to 55% by weight of mica. Sandwich structure elements are obtained which are particularly dimensionally accurate and which adhere well. The effect is believed to be based on a non-homogeneous curing reaction of the mixture which reacts to form polyurethane, due to the presence of mica.

Polyurethane sandwich structure element and process for production

A known herbicide such as a urea, carboxylic acid ester, aminoacid, benzoic acid derivative, benzonitrile, phenol derivative, diphenyl ether, carbamate, phenoxyalkanecarboxylic acid, triazine, triazinone, triazinedione, heterocycle, dipyridil derivative or benzosulphonamide, is rendered more effective by being combined with a synthetic spreading agent such as a silicone oil, fatty acid ester or fatty alcohol, e.g. isopropyl myristate, metamitron, ametridion or methabenzthiazuran.
