For copolymer resins
, the resin name is preceded by a weight percentage value of D or melamine; for example, Resin 83.0%DUF1.25 indicates that its D/(D + U) weight ratio is 83.0 percent with an overall F/(D + U) mole ratio of 1.25.
For DTOF copolymer resin
, the adsorption capacity of the resin for Ni(II) increases gradually with time to approach maximum value and finally attain equilibrium at nearly 6 hr.
The average annual growth rate of demand for EVAL[TM] EVOH copolymer resins
is expected to be 10% over the next decade.
having 40 percent by weight of their petro phenol replaced by chemicals derived from biomass residues, including rice (Oryza sativa L.) hull, rice bran, sugarcane (Saccharum officimarum L.) bagasse, and Taiwan acacia (Acacia confusa Merr) bark and foliage were synthesized.
The level of UV stability achieved is now similar to neat UV acetal copolymer resin
Lexan EXL glass-filled polycarbonate-siloxane copolymer resin
provided excellent stiffness and a high degree of impact over a very wide temperature range.
The reaction temperature was raised and the reaction was allowed to continue at 70[degrees]C for 45 minutes to graft the resorcinol onto the copolymer resin
. Variations in final resin viscosity were partly due to differences in the reactivities of different biomass extracts and also differences in cool-down rates.
The 3-layer film structure comprised 100% Exceed mPE resin in the outer layers and 15% Vistamaxx PBE and 85% Nexxstar EVA copolymer resin
in the core.
"The company's Lexan HPX copolymer resin
series offers new improvements to balance flow and impact, while new grades of Lexan HP resin give customers yet another option for higher-flow healthcare materials," said O'Brien.
Like all SKB iSeries Injection Molded Mil-Standard Waterproof Utility Cases, the 3i-1510-4, 3i-1510-9, and 3i-1717-10 are molded of ultra high-strength polypropylene copolymer resin
, and feature a gasket-sealed, water- and dust- tight, submersible design that is resistant to corrosion and impact damage (MIL-STD-810G).
Seawax Marine Coatings has obtained a patent for a formulation of an antifouling coating for application to submerged substrates comprised of at least 30 percent by weight of water, relative to the total weight of the formulation, at least 10 percent by weight of dry extract, relative to the total weight of the formulation, of a water repellent which is a mixture of a silicone resin, a polyurethane resin and an acrylic-styrene copolymer resin
, and at least 5 percent by weight of dry extract, relative to the total weight of the formulation, of an anti-adhesive active agent.
SABIC's Innovative Plastics business has released a high-performance Lexan EXL copolymer resin
that the company says "addresses the fast-moving trend toward miniaturization of photovoltaic (PV) connectors and junction boxes." The enhanced electrical and flame-retardant performance of this Lexan EXL resin grade enables designers to miniaturize the entire system by creating thin-wall parts, moving conductors closer together and integrating junction box systems, "helping to drive down solar energy costs and increase efficiency," Sabic says, adding that the PV market is one of the most dynamic global sectors, with compounded annual growth rates above 20%, and one that receives "significant attention as a viable and growing mainstream alternative energy source." www.sabic.ip.com.
