摘要:
A crosslinkable bioplasticizer is disclosed, a mixture of an epoxy-functional bio-derived plasticizer and an aromatic dianhydride. When heated, the mixture crosslinks, which can be accelerated by the addition of a Lewis Acid metal catalyst. The crosslinked bioplasticizer can be melt compounded into a thermoplastic resin or can be formed in situ in the thermoplastic resin. The crosslinking of the bioplasticizer can reduce blooming of the bioplasticizer to the surface of a plastic article made by extrusion, molding, calendering, or thermoforming techniques.
摘要:
A non-halogenated flame retardant thermoplastic compound is disclosed. The compound comprises one or more grafted polyolefin resins, non-halogenated flame retardant, non-halogenated processing aid, a compatibilizer, and, optionally, other additives. The non-halogenated processing aid found to be useful, among several candidates, was a dendritic polymer.
摘要:
A mixture of poly(vinyl chloride) and epoxidized methyl soyate is disclosed. The epoxidized methyl soyate as a plasticizer replaces butyl benzyl phthalate which is conventionally used for the manufacture of multi-layer laminate sheet flooring or single layer tile flooring. The epoxidized methyl soyate, a bio-plasticizer, unexpectedly is a “drop-in” replacement for the butyl benzyl phthalate, both in terms of processing and performance. Also poly(vinyl chloride)-epoxidized methyl soyate mixtures have much better heat stability than poly(vinyl chloride)-butyl benzyl phthalate mixtures.
摘要:
A blend of styrene-isobutylene-styrene based thermoplastic elastomer and organoclay-filled polyamide is disclosed which has good processability and more effective barrier properties for oxygen than the blend using amorphous or crystalline polyamide without organoclay.
