PolyBlend

SMOOTH AND PLIABLE; STRETCHING BEYOND THE BOUNDARIES. 

Aromatic Thermoplastic Polyurethane Elastomers

PolyBlend is a family of exceptionally soft, aromatic polyurethane elastomeric alloys, which can be used as a substitute for natural rubber or latex in many applications. 

These polymers encompass unique characteristics such as low flexural modulus, moderate tensile strength, and high elongation, in addition to allowing for a high draw-down ratio due to its superior melt strength and chemical integrity.

 

PolyBlend can be processed on conventional extrusion or injection molding equipment and is available in hardnesses ranging from 45 Shore A to 80 Shore A.

PolyBlend 1100 processing can be optimized by drying to a moisture content equal to or less than 0.05% by weight prior to melt processing. 

Typically, the pellets must be dried for 3-4 hours with a dryer inlet air temperature of 180ºF +/- 20ºF. We recommend a machine-mounted desiccant-type hopper dryer, capable of reaching and maintaining a dew point of -40ºF.  If dry times are in excess of 8-10 hours, a hopper dryer temperature of 120-150ºF is usually sufficient to achieve optimal moisture content.
