Abstract:
The present invention relates to an environmentally friendly flame-retardant polycarbonate resin composition having scratch resistance, which includes a specific (meth)acrylic flame-retardant copolymer to improve flame retardancy and scratch resistance.
Abstract:
An eco-friendly (meth)acrylic flame retardant copolymer includes a phosphorous-based acrylic monomer to provide a high index of refraction and excellent flame retardancy.
Abstract:
A (meth)acrylic copolymer is a copolymer of a monomer mixture including a phosphorus-based (meth)acrylic monomer represented by Formula 1, and a monofunctional unsaturated monomer. The (meth)acrylic copolymer can have improved refractive index, excellent flame resistance, transparency, scratch resistance and/or environment-friendliness: wherein R1 is hydrogen or methyl, R2 is a substituted or unsubstituted C1-C20 hydrocarbon group, R3 and R4 are the same or different and are each independently a substituted or unsubstituted C6-C20 cyclic hydrocarbon group, m is an integer from 1 to 10, and n is an integer from 0 to 5.
Abstract:
A resin composition includes a phosphorus-based acrylic copolymer (A) including (a1) an acrylic monomer represented by Formula 1 and (a2) a phosphorus-based acrylic monomer represented by Formula 2 as defined in the specification. The resin composition can have flame retardancy, heat resistance, mechanical properties, and/or flowability, while maintaining properties of high transparency and scratch resistance.
Abstract:
The present invention relates to a foam polystyrene-based bead. The foam polystyrene-based bead includes: a core containing a styrene-based resin, a char-generating thermoplastic resin, and an expanded inorganic material; and a skin disposed on the surface of the core, wherein the skin contains a resin of which the glass transition temperature is below around 120° C. The foam is contained in the core or skin. The core may further include a carbon filler. Foam produced from the expandable polystyrene beads is not an inherently self-extinguishing flame retardant material yet can have good non-flammability comparable to or better than that of inherently flame retardant materials (Non flammability level 3) as measured in accordance with KS F ISO 5660-1, heat insulation properties, and mechanical properties.
