The active substance of Silanogran PV is a low molecular polybutadiene containing silane groups which react by means of their reactive alcoxy groups (trimethoxy groups) and the silanol-groups-con-taining surfaces of silica and silicate fillers. The unsaturated polymer chains of Silanogran PV are integrated in the rubber matrix during vulcanization.

- Compatible Polymers & Resins
- Plastics & Elastomers End Uses
- Application
The application of Silanogran PV results in an improvement of the curing properties as stated below
- shorter curing time at equal scorch time
- better processability of the uncured compounds by lowering the Mooney Viscosity
- increase of tensile strength, modulus and tear resistance
- improvement of Compression Set
- decrease of abrasion
- minimized water absorption i. e. better electrical properties of cable compounds
- increase of dynamic properties
- Dosage
Silanogran PV is usually dosed between 1–6 weight percent calculated on silica fillers. A special mixing sequence does not have to be observed.
