Abstract
The invention relates to a decorative material which comprises a polyethylene glycol having a number average molecular weight in the range of 1,500 to 35,000 g/mol, in the form of solid, flake-like or powder-like particles with a bulk density of between 0.3 and 1.1 g/cm3 and a particle size of between 1 μm and 20 mm; and to a method for producing same.
Claims14
A decorative material comprising a polyethylene glycol having a number-average molecular weight in the range from 1500 to 35 000 g/mol in the form of particles that are in solid form or in the form of flakes or powder and have a bulk density of 0.3 to 1.1 g/cm3 and a particle size of 1 μm to 20 mm.
A process for producing a decorative material, comprising the steps of converting liquid polyethylene glycol to a solid form, by solidifying the liquid polyethylene glycol on cooled belts or rollers and then comminuting it to a particle size of 0.1 mm to 20 mm to give flakes.
A process for producing a decorative material, comprising the step of converting liquid polyethylene glycol to a solid form, by processing the liquid polyethylene glycol in a cold spraying system to a particle size of 1 μm to 1000 μm to give spray powder.
A process for producing a decorative material, comprising the step of converting solid polyethylene glycol to powder form, by comminuting the solid polyethylene glycol by means of a grinding process to a particle size of 1 μm to 1000 μm to give ground powder.
