This invention relates to a blend of polymers having electrostatic dissipative properties. The blend in particular comprises a thermoplastic base polymer, electrostatic dissipative agent and acrylic ESD enhancer.

Blends of thermoplastic polymers, electrostatic dissipative polymers and electrostatic dissipative enhancers

A compatibilized blend of a thermoplastic elastomer and a polyolefin. The compatibilizer is a thermoplastic polyurethane formed by the reaction of a substantially hydrocarbon intermediate such as a polybutadiene polyol, a diisocyanate such as MDI, and an amine or diol chain extender such as neopentyl glycol. The compatibilizer has high amounts of soft segments therein and imparts improved properties to blends of a thermoplastic elastomer and polyolefin such as good impact resistance, good tensile strength, good tear resistance, and good delamination resistance.

Compatibilized blends of a thermoplastic elastomer and a polyolefin

The present invention relates to electrostatic dissipative polymeric compositions comprising a polyether polyurethane which can be blended with one or more base polymers. In some applications, the polyurethane is useful without further blending. Further, the polyurethane blends can be blended with glass beads or glass fibers which have a synergist effect when combined with the electrostatic dissipative agent.

Chain extended low molecular weight polyoxiranes and electrostatic

An in situ polymerized thermplastic resin incorporating hollow glass spheres, which are incorporated during polymerization of the resin, and a method of making a concentrate of hollow glass spheres dispersed in a thermoplastic resin with minimal sphere fracture by adding the spheres during polymerization of the resin.

Method for reducing hollow glass sphere fracture in thermoplastic resin

An improved moldable low density thermoplastic composite containing hollow glass spheres comprising a blend of thermoplastic resin, glass fiber reinforcement, and a concentrate of hollow glass spheres dispersed in thermoplastic resin.

Moldable low density thermoplastic composite with hollow glass spheres

An extrusion die having a linearly movable mandrel that controls the thickness of the extrudate as it emanates from the die head. A piston within the die head is made part of the mandrel to control the position of the mandrel's edge relative to the die's outlet opening, with sensing means in the die assembly and being operative to provide a signal indicative of the relative position of such mandrel to the die head.
