A process for the preparation of artificial resin compression mixtures

Artificial resins, solid but in the resol condition, are finely powdered and mixed with finely powdered filling material, and the mixture subjected for a short time to high temperature and pressure so as to cause the resin to fuse and flow in the filler while not advancing it beyond the mouldable state. The product may be reduced to powder before use. The treatment may be effected by heat and pressure between two plates, or by extrusion through heated nozzles. The process is applicable particularly to resins of the phenol-formaldehyde type. The filler may be wood powder, fibrous materials, asbestos, talc, lithopone, magnesia, &c. Pigments may be included and agents such as stearin for preventing adhesion to moulds.

Pigmentation of thermoplastic filament-forming polymers

A process for pigmenting a thermoplastic filament-forming polymer, comprises dry blending powdered polymer with pigment and then centrifugally milling (grinding) the mixture to disintegrate pigment agglomerates and disperse same throughout the polymer. The pigmented polymer may then be fused, with or without additional polymer, and shaped e.g. to filaments or fibres. The milling may be by centrifugally propelling of mixture against a series of rotating pins. In examples polypropylene is pigmented with (I) carbon black, and (II) Monastral Blue.

A method of manufacturing foamed polystyrene balls

A method of continuously manufacturing foamed polystyrene balls includes heating two flows of molten vinyl aromatic polymer 15, 16 to within 25 degrees of an expanding agentâ s critical temperature. The expanding agent is then added to one at a supercritical pressure and the flows are mixed. This mixture can then be extruded through holes in a cylindrical die 37 which are provided with knives to separate the extrusion into granules. A nozzle 13 directs a liquid jet at the die and an inlet 14 feeding a gas to the cutting chamber prevents it flooding. This process ideally produces almost spherical granules having a density less than 50g/l with most of the cavities being unlinked.

Preparing conductive molding compositions

To produce dimensionally stable molding compositions at elevated temperatures without undue stiffness, on a commercial scale, low density conductive carbon black agglomerated particles are finely divided to a particle size below 0.044 millimeter, e.g. by bombardment in a mill 16 containing rotating intermeshing pins. The reduced size particles are then added in a portionwise manner to a PVC resin in a closed system e.g. including a high intensity vortex mixer 22, in a continuous process. The process ensures more uniform dispersion of the carbon black into the PVC resin and uniform bulk and surface properties of articles molded from the resultant resin. ...

COMPACTED PELLETIZED ADDITIVE BLENDS CONTAINING A POLYMER CARRIER

Improved solventless processing technology for additive blends containing a polymer carrier, including those which have high level of additives, is described. High concentrations of low-melting, sticky additives lead to phase separation and extrusion instability, such that pellets cannot be formed from such additive blends by traditional extrusion process. These blends include those with a high level of active additives that have been described in the literature as Type A Superblends. Here a polymer typically acts as the carrier of the additives. The new and improved technology involves the solid state compaction processing, using a tubular die, of such impossible-to-pelletize additive blends of the Type A composition to produce commercially useful pelletized additive blends. 1.
