摘要:
The invention relates to a flame retardant (meth)acrylate composition combining an impact-resistant (meth)acrylic polymer (such as Solarkote® resin from Trinseo) with specific levels of selected organic phosphinate and selected organic phosphorous flame retardants. The composition is halogen free, with superior flame performance, flowability and impact resistance. The composition of the invention is melt-processible and can be coextruded with a thermoplastic substrate material to obtain a multilayer structure, having a tough, impact resistant cap layer(s). The obtained multilayer structure can be further thermoformed into useful profiles and structures, such as the exterior housing of EV charging stations and car wash stations, automotive applications, aerospace, and building and construction applications.

There is provided herein a process for preparing cyclic phosphonate ester comprising reacting a glycol with at least one of phosphonic acid and phosphinic acid in the presence of a solvent. There is also provided a flame retardant comprising the cyclic phosphonate ester and industrial applications containing a flame retardant effective amount of the cyclic phosphonate ester.
摘要:
This invention provides a flame retardant pre-expanded polymer material comprising: (A) a thermoplastic polymer material; (B) an organic phosphorus-containing compound; and (C) a hindered amine having an OR group substituted directly on its N-atom, wherein R is a saturated or unsaturated hydrocarbyl group;
wherein the phosphorus-containing compound (B) is not a phosphoric ester or a phosphate, and wherein the weight ratio (B)/(C) is from 1.9 to 10. This invention also provides a process for producing the material, and a foamed article prepared by in-mold foaming or extrusion-foaming the material.
摘要:
A flame retardant resin composition which has high flame retardancy and excellent physical properties and comprises a resin obtained from a plant-derived raw material and a molded article thereof. The flame retardant resin composition comprises: (A) 100 parts by weight of a resin component (component A) which contains at least 50 wt% of a resin (component A-1) obtained from a plant-derived raw material; and (B) 1 to 100 parts by weight of an organic phosphorus compound (component B) represented by the following formula (1). (in the above formula, X 1 and X 2 are the same or different and each an aromatic substituted alkyl group represented by the following formula (2): in the above formula, AL is a branched or linear aliphatic hydrocarbon group having 1 to 5 carbon atoms, Ar is a phenyl group which may have a substituent, naphthyl group which may have a substituent or anthryl group which may have a substituent, n is an integer of 1 to 3, and Ar may be bonded to any carbon atom contained in AL.)

A non-halogen flameproof polycarbonate resin composition of the present invention comprises (A) about 30 to about 100 % by weight of a polycarbonate resin, (B) about 0 to about 70 % by weight of a rubber modified aromatic vinyl resin, and (C) about 0.5 to about 30 parts by weight of a phosphorus compound represented by the following Chemical Formula (I) or a combination thereof, based on about 100 parts by weight of the base resin including (A) and (B). The present invention can provide a polycarbonate resin composition which have excellent flame retardancy, and get environmentally friendly because any hydrogen halide gases were not generated during processing and combustion.
wherein R 1 and R 2 are each independently C 1 to C 10 alkyl, C 5 to C 7 cycloalkyl or phenyl.
