Provided are a halogen-free resin composition for a heat-shrink tubing having a combination of mechanical properties and flame retardancy and improved colorability, and a heat-shrink tubing manufactured using the resin composition. The resin composition includes 30 to 100 parts by weight of a phosphorus-based flame retardant, except red phosphorus; and 5 to 15 parts by weight of a silicone-based secondary flame retardant, per 100 parts by weight of a base resin, and the base resin is ethylene vinyl acetate copolymer obtained by polymerizing 15 to 33 weight% of vinyl acetate monomer and having a melt flow index between 2 g/10 min and 15 g/10 min.
摘要:
Compositions are disclosed comprising (i) a high molecular weight base polymer, and (ii) a relatively low molecular weight ester copolymer comprising an olefin and a copolymerizable ester, wherein the ester copolymer has a pour point less than 400C. In certain embodiments, the high molecular weight base polymer and the relatively low molecular weight ester copolymer are both selected from ethylene-based copolymers such as ethylene-vinyl acetate and ethylene-n-butyl acrylate.

A reclosable package for a plurality of products is described herein. The reclosable package includes an adhesive-based fastener that utilizes a low tack adhesive and pivotably connected first and second compartments, each compartment configured to receive the plurality of products therein. The adhesive-based fastener includes opposing portions of resealable adhesive on interior surfaces of the first and second compartments respectively, so that the interior surfaces can be pivoted together to close the reclosable package.
摘要:
La présente invention a pour objet une composition comprenant un mélange d'un agent réticulant et d'une première polyoléfine comprenant un monomère fonctionnel (X) choisi parmi les anhydrides d'acide carboxylique ou de diacide carboxylique insaturés, les acides carboxyliques insaturés et les époxydes insaturés apte à être réticulé avec une seconde polyoléfine pour former un ensemble (22) adhésivé à un support (24), ledit ensemble (22) et le support (24) formant une structure solidaire à deux couches distinctes (22, 24), caractérisée en ce que la quantité d'agent réticulant est supérieure ou égale à 5% de la masse totale de la composition. Ce mélange-maître permet, même en l 'absence de silanes, la réticulation de polymères, en particulier des polyoléfines, dont on veut augmenter la capacité d'adhésion à des supports tels que les polymères, les métaux, les oxydes de métaux ou le silicium. Ce mélange-maître peut être particulièrement utile pour l'encapsulation de cellules photovoltaïques.
摘要:
A dielectric weldable material includes a blend of at least two components including an inert polymer and an elastomeric polar polymer. A method of forming a bond includes providing a substrate having a first end and a second end, wherein the substrate includes a blend of at least two components including an inert polymer and an elastomeric polar polymer. The method further includes bonding the first end and second end of the substrate with high frequency electromagnetic energy.
