KVIS-200

KVIS-200 by Kothari Petrochemicals acts as a wetting agent and processing aid in filled and reinforced polypropylene. It is a clear, viscous, non-toxic and chemically inert polyisobutylene (PIB) grade. It plasticizes polypropylene (PP), polystyrene (PS), ethylene-vinyl acetate (EVA) copolymer resins, ester gums, and polyterpenes.

• It offers higher melt flow rate, greater elongation & improved impact strength in polypropylene random & impact copolymers, and improved flexibility, tear resistance, gloss & clarity in polypropylene homopolymer film applications.
• It improves the environmental stress crack resistance (ESCR) of high impact polystyrene (HIPS) to fats & oils, and also improves the melt flow in crystal polystyrene, better than mineral oil while maintaining higher strength & heat deflection temperature.
• It also increases the izod impact strength of acrylonitrile-butadiene-sytrene (ABS) resins and ethylene-propylene diene monomer (EPDM).
• It is used as an extender for a wide variety of vulcanized elastomers like natural rubber, butyl rubber, polyisoprene, polybutadiene (PB), ethylene-alpha olefin- and styrene butadiene rubber (SBR).
• It possesses high shear- & oxidative stability and resistant to exudation by heat aging.
• KVIS-200 is used to plasticize the roofing and pipe wrap compounds made from butyl rubber or EPDM modified butyl rubber.
• Provides excellent tensile strength, low temperature flexibility and color/UV-stability to the elastomers.
• It exhibits compatibility with the elastomeric portion of thermoplastic block copolymers such as butylene-ethylene-styrene block copolymer.
• In low concentrations, it softens the elastomers, and at higher levels, it offers tack & adhesion.
• It is suitable as masterbatch for stretch films and cling wraps.
• It has a shelf life of 12 months.
