Abstract:
Significant disadvantages of the use of polylactic acid (PLA), lack of good heat stability and flame retardance, have been overcome by the use of an aryl phosphate in combination with talc. The compound achieves a threshold of 65° C. in heat deflection temperature and V-0 flame retardance at 1.6 mm thickness.
Abstract:
Low molecular weight polyphenylene ether (PPE) is made from higher molecular weight PPE without using solvents by extruding the higher molecular weight PPE with a phenolic modifier and a redistribution catalyst. The low molecular weight PPE has a Mw/Mn polydispersity greater than about 2 and a Mn ranging from about 10,000 to about 20,000.
Abstract:
A masterbatch containing one or more colors of decorative particulate additive is disclosed and is particularly suitable for use in thermoplastic elastomer plastic articles.
Abstract:
A completely non-halogenated flame retardant polycarbonate compound is disclosed. The compound comprises a polycarbonate, non-halogenated drip suppressant ingredients which react in the presence of heat to form a drip suppressant adduct, and a non-halogenated char former. The compound can achieve a UL 94 rating of V-0 at a thickness of at least 3.2 mm and otherwise achieves no dripping/igniting of the cotton indicator during that test.
Abstract:
An inkjet ink container is disclosed comprising a polymer compound comprising an oxygen scavenging composition. The oxygen scavenging composition is selected from the group consisting of copolymers of polycondensate segments and oxygen scavenging moiety segments; oxygen scavenging unsaturated polymers; oxygen scavenging dendrimers; molecular hydrogen generators; and combinations thereof.
Abstract:
A formwork assembly is adapted to receive concrete to produce structures such as wall structures. The formwork includes PVC tubular form elements having recessed female engagement portions. The female engagement portions are adapted to receive respective male engagement portions. An octagonal form element has a female engagement portion positioned at each vertex between adjacent sides. A recessed female engagement portion is closed to the interior of the form element but open to the exterior of the form element. Thus, the form element includes a plurality of vertices open to the exterior. The form elements also include male engagement portions at an open side. Wall panels, corner panels, and joint connectors can also include male engagement portions. The male engagement portions and female engagement portions are adapted to mate to form a formwork arrangement having a substantially flat exterior wall. A formwork assembly can additionally include concrete flow apertures and insulation.
Abstract:
Use of polycaprolactone plasticizer is disclosed for flexible polyvinyl chloride compounds. The compounds can pass the very demanding UL-910 plenum burn test for usage in wire and cable articles.
Abstract:
Significant disadvantages of the use of polylactic acid (PLA), lack of good heat stability and flame retardance, have been overcome by the use of resorcinol bis(diphenyl phosphate) in combination with talc. The compound achieves a threshold of 65° C. in heat deflection temperature and V-0 flame retardance at 1.6 mm thickness.
Abstract:
A thermoplastic elastomer compound of an acrylic-containing styrenic block copolymer and plasticizer oil have been found to be capable of sintering at a temperature ranging from about 180 C to about 200 C when the copolymer and the oil are in no more than a 2:1 weight ratio. The compound can be used in rotomolding or slush-molding equipment to make plastic articles having elastomeric properties.
