A swelling agent dispenser (2) for feeding a swelling agent from the swelling agent reservoir (7) to a swellable substance cartridge (3) which can be connected to the swelling agent dispenser (2).
Polymer nanocomposites comprising an untreated phyllosilicate, a delaminating agent, a swelling agent, and a polyorganosiloxane - polycarbonate copolymer are disclosed.
The composition includes a matrix forming agent and a swelling agent and is suitable for once daily oral administration.
The film is swelled by carrying out the cross-linking in the presence of a swelling agent or the film is mixed with the swelling agent after cross-linking.
At least one swelling agent is thus placed in active contact with said body, which may swell on absorbing substances.
The blowing agent has a primary blowing agent of isobutane and a secondary blowing agent of 1,1,1-trifluoroethane, 1,1,1,2-tetrafluoroethane, or a blend of them.
The foamable compositions further comprise a blowing agent.
A blowing agent combination of a chemical blowing agent with expandable microballoons provides for especially good energy absorption.
These foams were produced using aqueous blowing agents comprising water as the only blowing agent, or mixtures of water with another blowing agent material.
The amount of a fluorocarbon blowing agent can be reduced by using water as the blowing agent.
The invention relates to a method for producing styrene polymers containing water as only inflating agent by polymerising styrene in an aqueous suspension.
The invention relates to a method for producing polystyrene foam particles, according to which polystyrene beads containing water as only inflating agent are expanded.
The inventive method includes the following steps: mixing a metal with an expanding agent, obtaining a material containing said expanding agent and treating the said material thermally.
The thermally expandable microcapsule comprises a shell composed of a polymer and a volatile expanding agent as a core agent encapsulated in the shell.
Method and apparatus (11) for feeding an expanding agent into a machine (1) for the extrusion of polymeric material.
The addition of an expanding agent such as butyl isocyanate to the raw composition makes it possible to prepare an expanded material with completely closed pores.
Rubber water-blocking rings (4) containing an expanding agent are sleeved on the outer wall of the water pumping pipe (5) at intervals.
The secondary ingredient component of the creamer compositions of the present invention comprises an emulsifier and a bulking agent.
Disclosed is a soft, chewable dosage form, including a matrix of hydrogenated starch hydrolysate, a water soluble bulking agent, and a water insoluble bulking agent.
The bulking agent of the present invention comprises a starch hydrolysis product, a bulk sweetener, and an emulsifying agent.
These preparations may further comprise a plasticizer and/or a bulking agent.
The foam is blown without chemical blowing agent and is highly thermoformable.
Between the housing and the pipe there is a substantially sealed annular space filled with a swellable material.
The blowing agent is directed to achieving low fugitive VOC emissions.
The swellable material is especially based on expanding graphite and is preferably inserted in loose form.
A formulation includes a polymeric material, a nucleating agent, and a blowing agent.
The composition may further comprise a catalyst and blowing agent.
The low calorie bulking agent 1,4-anhydro-L-glucitol is also described.
The film-forming compositions herein comprise a film-forming polymer and a zwitterionic bulking agent.
A hydrophobic biodegradable material contains host material and foamer.
A, a prienoxy resin, an impact modifier inciuding methacryiate- butadiene-styrene, a curing agent; and a blowing agent.
Other components include polyol, intumescent char-forming agent, and melamine, which acts as a blowing agent.
