One embodiment of the present invention provides a polyamide powder, which includes polyamide particles having

Polyamide fluidized-bed-coating powder for thin-layer fluidized-bed coating

A composition containing from 88 to 99.99% by weight of a polyamide, a compound of a polyamide and mixtures of these, and from 0.01 to 0.25% by weight of a flow aid where the drying loss from the flow aid after 5 days of conditioning at a relative humidity of 95% is less than or equal to 1%, determined by ISO 787/2.

Polyamide powder with long-lasting, consistently good flowability

A sintering powder containing polyamide polymer and titanium dioxide particles, a process for laser sintering, and moldings produced from the sintering powder. The moldings formed using the powder of the invention have improved surface quality due to the powders having increased yellowing resistance when exposed to thermal stress during laser sintering. Moldings produced from the sintering powder have improved mechanical properties, in particular modulus of elasticity.

Laser-sintering powder containing titanium dioxide particles, process for its preparation, and moldings produced therefrom

A process for producing shaped articles are prepared by a process comprising selectively laser sintering a nylon-12 pulverulent material having the following characteristics:

Fusible adhesives which contain a copolyamide and an isocyanatoisocyanurate obtained by trimerization of isophorone diisocyanate do not undergo crosslinking during melt mixing, exhibit an improved resistance to decomposition during washing and dry cleaning, and are useful for coating textile fastening inserts.
