A heat-absorbing system comprising at least a first layer (A) containing a ultraviolet absorber, a second layer (B) containing an organic infrared absorber and ultraviolet absorber and a third, interference layer (C) reflecting in the infrared range is disclosed. The system is suitable for shielding plastic glazing elements from heat radiation.

Heat-absorbing layer system

A flame retardant thermoplastic molding composition is disclosed. The composition contains an amorphous thermoplastic polymer, at least one flame retardant in the form of a fully or partially halogenated sulfonic acid salt and at least on alkaline earth metal sulfate and/or one oxide having an average particle size of up to 400 nm.

Flame-resistant thermoplastic molding material

The use of zwitterionic compounds as mold release agents in thermoplastics is disclosed. Molding compositions having good release properties, preferably compositions containing polycarbonate resins are thus disclosed.

Use of zwitterionic compounds as mold release agents in thermoplastics

A thermoplastic molding composition comprising polycarbonate resin having improved mold release properties is disclosed the composition contain polycarbonate resin and 0.005 to 5.0% relative to the weight of the composition of at least one hydrocarbon in the form of C15 -methyl-branched alkane. The hydrocarbon is characterized in that the weight proportion of its branches is 5 to 30 percent relative to the weight of carbons in the alkane chain.

Polycarbonate molding compounds with good demolding properties and molded bodied and semifinished products produced from the same

A molding composition suitable for the preparation of glazing is disclosed. The composition contains a transparent thermoplastic polymer and a phthalocyanine or naphthalocyanine. Also disclosed is a method for preparing the composition.

Molding materials

The invention provides X-ray contrastable plastics materials with low-molecular weight iodine compounds, a process for preparing X-ray contrastable plastics materials with low molecular weight iodine compounds, the use of low molecular weight iodine compounds to improve the X-ray contrast in transparent plastics materials and toys with improved X-ray contrast containing low molecular weight iodine compounds.

Plastic molding materials which can be detected by X-ray contrast

A method of using oligocarbonates having terminal groups containing iodine to prepare molded articles (e.g., toys and medical equipment) having high X-ray contrast is described. The oligocarbonates contain more thaan one diol unit, and have a weight average molecular weight (Mw) of less than 3000.
