Green strength is a term used to express the strength, cohesive force of rubber compounds in their raw state, before being cured. Green strength of silicone compounds becomes an important factor when processing them on equipments originally designed to handle organic rubber, particularly calanders.
General grade silicones compounds, regardless of hardness, are normally being faced with the problem of having an insufficient green strength and too high elongation to be used on calanders and hence for manufacturing of silicone hoses, particularly when reinforced with a stretchable fabric needed for curved automotive turbocharger or coolant radiator hoses. A high-green-strength silicone rubber is ideally needed for such application. We are able to prepare a customer specific silicone compound, by varying green strength of any silicone compound.
