Chemical stability of KVIS Polyisobutylene's is much superior to unsaturated mineral oil because of its high saturation. KVIS Polyisobutylenes have a very low acid value. Only severely high temperatures can cause decomposition.

Solubility and Compatibility

KVIS Polyisobutylene's are soluble in Non-Polar Solvents and insoluble in Polar Solvents. Sometimes, polymer molecular weight can influence solubility.
