Kenflex® and Kenplast® Plasticizers

KENFLEX® A Molecular Structure [Melt Point = 80°C (175°F)]

Kenflex Molecular Structure

Kenrich Petrochemicals, Inc.’s (“Kenrich”) Kenflex® polymeric resin softners and Kenplast® monomeric plasticizers typical advantages in various polymers are: superior processing; nerve reduction; improved extrusion; excellent electrical properties; good wetting of fillers; excellent mold flow and release; high temperature stability; scorch control; permanence; non extractability; non volatility; non migratory; excellent physicals at large doses (except peroxide cures); coupling for poly blends; and significant performance over coumarone resins. Some specific benefits for Kenflex® A powder and Kenflex® N liquid are as follows:

Chloroprene: Retards significantly the crystallization rate of Neoprene. An unplasticized control reached half crystallization in 44 hours, while the addition of KENFLEX® A required 220 hours using the Dilatometer Method. The Durometer Hardness showed a six-fold improvement over process oil.
Chlorosulfonated Polyethylene: Moderate quantities improve tack, decrease hardness somewhat, and have a minimal effect on tensile, modulus and elongation. Improves electrical and aging properties.
Butyl: Outstanding for improved ozone resistance.
Polysulfide: Overcomes high solvent resistance of polysulfide polymers to act as an excellent process aid and softener.
Polar Thermoplastics: The 240oC flash point, relatively high molecular weight and polar nature of Kenflex® A makes it an excellent candidate for thermoplastics not requiring UV discoloring resistance.

Kenplast® G aromatic distillate acts as non-reactive diluent in Epoxy and Urethane and as a plasticizer in PVC and Nitriles where UV color is not a concern. Kenplast® ES-2 cumylphenyl acetate acts as a reactive diluent for high performance epoxy formulations.
