摘要:
An organophosphorus compound useful in a phosphorus containing flame retardant and a flame retardant polyurethane foam, where the organophosphorus compound is shown in Formula (I) where Y is selected from the group consisting of an —OH group, an —NH2 group, an —NHR3 group, and an —SH group, where R3 is a monovalent hydrocarbyl group having 1 to 10 carbon atoms; R is a divalent hydrocarbyl group; X is a heteroatom group; and R1 and R2 are each independently a substituted or unsubstituted hydrocarbyl group, wherein R1 and R2 can be optionally joined to form a ring.
摘要:
Polymer foam bodies are made from phosphorus-containing thermoplastic random copolymers of a dialkyl (meth)acryloyloxyalkyl phosph(on)ate. Foam bodies made from these copolymers exhibit increased limiting oxygen indices and surprisingly have good properties. In certain embodiments, the phosphorus-containing thermoplastic copolymer is blended with one or more other polymers and formed into nanofoams.

Embodiments of the invention include a phosphorus containing flame retardant which may be the reaction product of a reaction mixture where the reaction mixture includes at least one first polyol and at least one phosphorus containing compound having the general formula (1), (2) or combination thereof:
摘要:
Photovoltaic or solar module frames, racks, or frame or rack components are made from a composition comprising (A) a thermoplastic polymer, particularly a thermoplastic polyolefin, (B) a reinforcing element, particularly glass fiber, (C) a non-halogen containing, intumescent flame retardant, (D) an impact-modifier, particularly a polyolefin elastomer, (E) a coupling agent, and, optionally, (F) one or more additives such as an antioxidant, UV-stabilizer, etc. These frames provide for easy assembly without the need for screws, bolts or other metal fasteners.
摘要:
The present disclosure provides a composition which includes a thermoplastic polyurethane, a flame retardant, and an epoxidized novolac resin. The flame retardant may be selected from one or more of the following: a melamine-containing compound, a nitrogen/phosphorus-based flame retardant, a phosphorus-based flame retardant, a metal-5 containing flame retardant, and combinations thereof. The composition may be a component of an article such as a coated wire or cable, with the composition present in the coating.
