Table 1 shows the physical properties of the slabs prepared directly from re-vulcanized DVR, without any virgin elastomer included in the compound, with variation in crumb origin and curatives concentration.
The data in table 4 are for a blend of 70% DVR with natural rubber but also including additional carbon black, plasticizers and various curatives.
The DVR can be vulcanized with the conventional curatives and processed in standard mixers and on a two roll mill.
are normally well distributed after 100-120 secs.
These curatives are used alone and in conjunction with other curatives finding utility in flexible elastomer systems, coatings and adhesives.
These curatives produce moderate to high durometer systems with good to excellent properties.
Diol curatives - Butane diol, hydroquinone di (B hydroxy ethyl ether), (HQEE) and butanediol (BDO), together with minor amounts of 2-ethyl-2-(hydroxy methyl)-1,3 propane diol (TMP), are the main curatives for moderate and high durometer MDI prepolymer systems.
Offers curatives for use with high-performance, heat-cured polyurethane elastomers.
