摘要:
A stabilized powdered endothermic blowing agent .[.which.]. is a mixture or a polycarboxylic acid and an inorganic carbonate, .[.and.]. .Iadd.the .Iaddend.polycarboxylic acid and inorganic carbonate each having been surface treated with a component which prevents water from being absorbed thereby. The blowing agent is incorporated into a polymeric concentrate used for producing foamed products.
摘要:
Compositions for producing foamed products which include filler and/or pigment additives and blowing agents which enhance the strength of weld lines which are produced when the compositions are molded. The products produced from the compositions have weld line that demonstrate superior strengths as compared to similar foamed products which do not utilized the particular blowing agents.
摘要:
Compositions for producing foamed products which include additives and blowing agents which cause the surface treatment additives to migrate to the surfaces of foamed products. The products produced from the compositions require less additives because the incorporated additives are concentrated at the surface thereof.
摘要:
A high temperature endothermic blowing agent which is a mixture of a polycarboxylic acid and an inorganic carbonate, the polycarboxylic acid and inorganic carbonate each having been surface treated with a component which prevents water from being absorbed thereby. The blowing agent is incorporated into a polymer and used for producing foamed products.

摘要:
In apparatus and processes for producing pellets of plastic resins and additives, the heat collected in the quench water of the pelletizer device is used to heat the plastic entering the process. This simple unique idea has an energy saving in the process.
