Abstract

The invention relates to a cross-linking masterbatch comprises more than 40 % by weight of organic peroxide, a synthetic rubber, and a specific silica. More specifically, a highly concentrated cross-linking masterbatch is provided comprising from 40 to 70 % organic peroxide, a synthetic rubber such as EPM and/or EPDM, preferably having a propylene content of 45 % or more and a Mooney viscosity at 100 °C of 30 or more, and a wet-treated and/or dry-treated silica having a specific surface area of 150 m2/g or more or a porous silica having a pore volume of 1.4 ml/g or more.

Claims

AMENDED CLAIMS[received by the International Bureau on 3 January 2001 (03.01.01); original claim 1 amended; remaining claims unchanged (2 pages)]
1. A concentrated cross-linking masterbatch comprising one or more organic peroxides, one or more synthetic rubbers, and silica, wherein said organic peroxide constitutes from 40 to 70% by weight, based on the total weight of the masterbatch, and said silica has a specific surface area of 150 m2/g or more or a pore volume of 1.4 ml/g or more, with the proviso that the masterbatch does not comprise a traπs-polyoctenamer.
2. A masterbatch according to claim 1 wherein the silica is characterized by (a) a specific surface area of 150 m /g or more if said organic peroxide is a solid at ambient temperature, or (b) a pore volume of 1.4 ml/g or more if said organic peroxide is a liquid at ambient temperature.
3. A masterbatch according to claim 1 or 2 wherein said synthetic rubber is an ethylene propylene rubber or an ethylene propylene diene rubber which preferably contains at least 45% by weight of propylene and has a Mooney viscosity at 1G0°C of 30 or more.
4. A masterbatch according to any one of claims 1-3 wherein said organic peroxide is present in an amount of from 42.5 to 65% by weight, said synthetic rubber is present in an amount of 10-30% by weight, and said silica is present in an amount of 5-30% by weight, relative to the total masterbatch weight.
5. A masterbatch according to any one of the preceding claims further comprising one or more inorganic fillers, preferably selected from the group of calcium carbonate, heavy calcium carbonate, talc, clay, and carbon black.
6. A masterbatch according to any one of the preceding claims further comprising one or more adjuvants selected from the group of antioxidants, UV stabilizers, flame retardants, pigments, dyes, processing oils, and lubricants, which preferably are present in an amount of less than 5% by weight, based on the weight of the total masterbatch.
7. Use of a masterbatch according to any one of claims 1-6 in the process of vulcanizing an elastomer.
