Abstract:
A modified polyester resin composition comprises a combination of a PET polyester, a PCT polyester, a CHDM modified copolyester comprising PCTA, PCTG or PETG, and a modified polymer at least comprising TPU or EPDM, wherein the modified polymer accounts for 3-25 wt % and the rest accounts for 97-75 wt %, based on the total weight of the resin; and the modified polyester resin composition is suited for use in a halogen-free, heavy metal-free, and volatile organic compound-free polyester-based plastic floor tile excellent in higher resistance to wear and tear, better tensile strength, more preferable resistance to both lit cigarette e and solvents, and particularly being friendliness to environment and not hazardous to health.
Abstract:
A thermosetting resin composition contains a primary resin formed from mixing a styrene-type polyphenylene ether resin thermally modified with styrene with an acrylic-type polyphenylene ether resin thermally modified with acrylic at a weight ratio ranging between 0.5 and 1.5, consequently having excellent heat resistance, flowability, and filling ability; and when cured, having a dielectric constant smaller than 3.0 and a dielectric dissipation factor smaller less than 0.0020 at the frequency of 1 GHz as well as a glass transition temperature higher than 210° C.; in application, the composition is suitable to impregnate reinforcement to form prepregs with excellent curability.
Abstract:
A heat-insulating transparent PVC sheet is formed from a PVC substrate having a thickness of 0.02-2.0 mm and contains heat-insulation pastes evenly distributed over the PVC substrate, since the heat-insulation paste contains an essential component of wolfram cesium powder (WCs) with a chemical formula of CsXNYWO3-ZClC and having a particle size of 0.005-2 μm, the heat-insulating transparent PVC sheet has an excellent weatherability, and particularly before and after tested in 300-hour service life in line with ASTM G-154 specification, has a physical property of weatherability decay rate (%) small than 4%.
Abstract:
An aluminum plastic film packaging material for lithium batteries to prolong service life, at least comprising an inner layer and an aluminum foil layer, is performed an anti-corrosion treatment between the inner layer and the aluminum foil layer by one of the following ways: 1) a chromium-containing anti-corrosion layer is formed from an aqueous modified resin containing trivalent chromium; and 2) an adhesive layer with non-chromium material is formed from an aqueous modified resin, an epoxy curing agent, a silane coupling agent and a nano-sized metal oxide particle.
Abstract:
A thermosetting resin composition due to containing a modified PPE resin as a main ingredient is suited for use in making a pregreg or a copper foil substrate, when hardened, featuring a small dielectric constant (Dk), a low dielectric dissipation factor (Df) and a high Tg as well as a high resistance to heat and flame, this outstanding result is because the modified PPE resin is formed with a novel two-dimensional hardenable structure prepared to have side-chain reactive functional groups being provided in addition to those at the terminal ends of the main chain of the PPE resin thereof.
Abstract:
A fluorocarbon resin composition is applicable to produce a prepreg for use in making a high-frequency circuit board, including a polytetrafluoroethylene resin; a fluorine-containing copolymer of poly fluoroalkoxy or fluorinated ethylene propylene; inorganic powders and an impregnation additive such as hydroxyethyl cellulose; resulted in that the prepreg is capable of increasing a plurality of times for proceeding impregnation-coating, the surface defects prone to occur on a fluorocarbon prepreg during drying, baking and sintering after impregnation are therefore improved at the same time.
