ELASTOSIL® AUX REPLASTICIZER 4 helps to replastify heavily crepe-hardened rubber compounds. Excessive crepe hardening of the rubber can be recognized by the rough surface of extrudates or difficult mold filling in compression molding processes. In such cases, the rubber must be replastified before compounding on a roll mill. Depending on the degree of crepe-hardening a dosage of 1 - 3 % is recommended. Using higher amounts of ELASTOSIL® AUX REPLASTICIZER 4 may result in a reduced Shore A hardness, especially when applied to ELASTOSIL® R and R plus grades with high hardness values.
Processing
Incorporation of ELASTOSIL® AUX REPLASTICIZER 4 into ELASTOSIL® R and R plus silicone rubbers is best done on tworoll mills. Depending on the degree of crepe-hardening, a homogeneous compound forms with time. Heavily crepe hardened rubber will tear at first, form an inhomogeneous network, or crumble. ELASTOSIL® AUX REPLASTICIZER 4 can be added subsequently to obtain a homogenous silicone compound with good processability. A total dosage of 1 - 3 % ELASTOSIL® AUX REPLASTICIZER 4 is recommended.
