摘要:
The present invention relates to thermoplastic resin compositions, particularly polyolefines, polyvinylchloride and polyamide. The thermoplastic resin compositions contain between 3 and 400% by weight of filler based on the weight of the resin, said filler comprising talc and microsilica where the weight ratio between talc and microsilica is between 15:1 and 1:15. The invention further relates to a method for the production of thermoplastic resin compositions, and to a filler blend for use in thermoplastic resins, said blend containing talc and microsilica in a weight ratio between 15:1 and 1:15.

Rubber powders with a high degree of filling are obtained by precipitating water-containing suspensions which contain fillers and rubber emulsions or rubber solutions. Use thereof to prepare vulcanizable rubber mixtures.
摘要:
The invention relates to a thermoplastic membrane (e.g. film, fluid barrier, and the like) which is formed from a blend of: a) a first polymer component (FPC), wherein said FPC comprises a propylene-ethylene copolymer containing from 80 to 93 percent by weight of units derived from propylene, and having a melting point derived from stereoregular polypropylene sequences, as determined by differential scanning calorimetry (DSC), in the range of from 25° C. to 70° C., and a heat of fusion of from 2 J/g to 25 J/g; b) an inorganic filler; c) a processing oil, and d) optionally, a second polymer component (SPC), wherein said SPC is a stereoregular polypropylene containing less than 7 percent by weight of units derived from ethylene or alpha-olefin monomer containing from 4 to 8 carbon atoms and having melting point, as determined by DSC, greater than 130° C., and a heat of fusion greater than 80 J/g.
摘要:
The present invention relates to a rubber composition which contains reinforcement selected from at least one of synthetic amorphous silica, carbon black and silica treated carbon black, non-alkoxysilane containing coupling agent, wherein at least one of said reinforcements is pre-treated prior to its addition to said rubber composition with at least one of an alkylsilane hydrophobating agent and/or non-alkoxysilane containing coupling agent, and to articles of manufacture, including tires, having at least one component comprised of such rubber composition.
