UHMW-PE's high molecular weight means it will not melt or flow as a
molten liquid. Processing methods are therefore derived from those of
powder metal technology. UHMW-PE cannot be transformed and molded by
conventional plastic processing techniques (injection molding, blow
molding or thermoforming). Compression molding is the most common
conversion process used with this resin, producing a stronger, more
consistent product.
