Phenyl ether polymers are a class of polymers that contain a phenoxy or a thiophenoxy group as the repeating group in ether linkages. Commercial phenyl ether polymers belong to two chemical classes: polyphenyl ethers (PPEs) and polyphenylene oxides (PPOs). The phenoxy groups in the former class of polymers do not contain any substituents whereas those in the latter class contain 2 to 4 alkyl groups on the phenyl ring. The structure of an oxygen-containing PPE is provided in Figure 1 and that of a 2, 6-xylenol derived PPO is shown in Figure 2. Either class can have the oxygen atoms attached at various positions around the rings.

High-thermal-filament ignition polyphenyl ether composition as well as preparation method and application thereof

ActiveCN112375367AHWI performance improvementQuality improvementPolyoxymethyleneCarbon layer

The invention discloses a high-thermal-filament ignition polyphenyl ether composition. The polyphenyl ether composition comprises the following components in parts by weight: 40-90 parts of polyphenylether, 2-40 parts of styrene resin, 1-10 parts of a toughening agent, 5-18 parts of a flame retardant, 0.1-3 parts of polyformaldehyde resin and 0.1-1 part of metal oxide. According to the heat-resistant wire ignition polyphenyl ether material, the quality of a carbon layer is greatly enhanced through the catalytic charring effect of metal oxide and POM in the early stage of ignition, the HWI performance of the material is obviously improved, a good effect on flame retardance is achieved, and the flame-retardant PPE material with the 0-grade HWI can be prepared through the method.

Oil-resistant EVA cable material and preparation technology thereof

ActiveCN109627666AGood oil resistanceExcellent flame retardancyPolyphenyl etherVinylsilane

The invention provides an oil-resistant EVA cable material and a preparation technology thereof. The cable material comprises, by weight, 50-70 parts of a vinylsilane/styrene grafted ethylene-vinyl acetate copolymer (EVA-g-VS/ST), 5-20 parts of polyphenyl ether resin, 15-30 parts of a fire retardant and 1-5 parts of a coupling agent; the VA content of the ethylene-vinyl acetate copolymer is 10-28%, and the vinylsilane/styrene grafted ethylene-vinyl acetate copolymer is prepared through a melt extrusion method under the effect of an initiator. According to the material, the technical problem issolved that the oil resistance of the ethylene-vinyl acetate copolymer with low VA content is low, and meanwhile the obtained cable material has excellent flame retardance and mechanical performance.
