GeneralCrafco PolyFlex Type 2 is a hot-applied, asphalt based product used to fill cracks and joints in asphalt or portland cement concrete pavements in moderate to warm climates. PolyFlex Type 2 is supplied in solid form which when melted and properly applied forms a highly adhesive and flexible compound that resists cracking in the winter and resists flow at summer temperatures. PolyFlex Type 2 is used in highway, street, airfield and parking lot pavements and is applied to pavement cracks using pressure feed melter applicators. At application temperature PolyFlex Type 2 is a medium viscosity product which flows and penetrates cracks. PolyFlex Type 2 is formulated as an economical yet effective pavement maintenance crack filling product. Compared to products based on reclaimed rubber, PolyFlex Type 2 offers lower viscosity for easier application, improved summer temperature pick-up resistance, quicker set times, and improved low temperature flexibility.
