A biocidal composition based on organic arsenic compounds, comprising at least one tin compound in an amount affective to prevent elution of the arsenic compound from a composition containing them, particularly molding compositions for the production of molded plastic articles, particularly based on flexible PVC and/or ethylene/vinyl acetate copolymers or graft polymers or, optionally, polyethylene, containing stabilizers imparting stability to light, weather and heat, and optionally conventional additives such as colorants, fillers and slip agents, and containing further an arsenic compound as a biocidal agent are treated with such tin compound to prevent elution of the biocidal compound.

Biocidal composition and its use in plastic molding compounds

A sealing sheet for the building industry made up of at least one layer which contains an elastomeric synthetic resin that is devoid of, i.e., free of vulcanization accelerator, and that contains fillers, especially carbon admixed with an ethylene-propylene-diene terpolymer and/or ethylene-propylene copolymer and which has, on the outside and/or between layers of a synthetic resin, a reinforcing layer laminated in place with the use of heat and comprised of a fabric, a mat, a knitted material, a nonwoven material, or a similar material formed of a synthetic resin and/or of glass fibers.

Sealing sheet of elastomeric synthetic resins with textile reinforcement

A multi-layered sealing sheet for the building industry is prepared so that all plies which contain elastomeric synthetic resins are devoid of vulcanization accelerator and consist of an elastomeric synthetic resin on the basis of ethylene-propylene-diene terpolymers and/or ethylene-propylene copolymers. A reinforcing insert is laminated in between the layers with the use of heat and is a fabric, a mat, a knitted material, or a similar material of synthetic resin fibers and/or glass fibers.

Multi-layered sealing sheet of elastomeric synthetic resin

An insulating panel suitable for the covering of roof structures includes a core layer of a synthetic foam material bonded adhesively on its top side to a sealing thermoplastic layer. The core layer is formed of an elastic closed-cell crosslinked polyolefin foamed material.
