According to SABIC the improved clarity in combination with the high stiffness opens up new opportunities for down-gauging products that are currently made in random copolymer
PR In addition its higher flow means it can process at lower temperatures, leading to potential energy saving up to 10 per cent.
Basell introduced Profax RP448S clarified random copolymer
, a 40-MFR reactor grade that contains no peroxide and is based on new catalyst technology.
The company offers liquid homopolymer polybutadiene and random copolymer
butadiene/styrene to enhance properties of UV/EB curable systems.
This observation suggests that compatibility of the M52N block-copolymer was improved by the P(MMA-co-DMA) random copolymer
. It has been shown previously in the literature that the DMA units in P(MMA-co-DMA) copolymer increased the miscibility and stability of block-copolymer nanostructures in thermosets (e.g., epoxy, unsaturated polyester) until completion of the polymerization reaction [28, 29, 41].
In 2007 LyondellBasell introduced its Stretchene branded random copolymer
polypropylenes aimed specifically at addressing rigidity, transparency coupled with high impact strength and production output.
Among the new grades are a 100-MFR random copolymer
for thin-wall injection molding that boasts outstanding taste and odor performance.
These easy-flow materials are said to combine the stiffness of a highly nucleated polypropylene homopolymer with the transparency of a state-of-the-art propylene-ethylene random copolymer
. (Targor GmbH)
The two companies say that "Agility NX resins bring together Dow's breakthrough polymer design and production capabilities for random copolymer
PP resins with Milliken's innovative Millad NX 8000 clarifying agent.
Figure 5 is used to display the measured peeling force results for all used ethylene copolymers on a common basis (comonomer mole%), because it scales well with the branching frequency along the linear random copolymer
According to SABIC: "The improved clarity in combination with the high stiffness opens up new opportunities for down-gauging products that are currently made in random copolymer
PP, resulting in thin-walled products with a very good transparency." In addition its improved flow enables reduction of processing temperatures, leading to potential energy savings up to 10 per cent.
A new EVA random copolymer
for oil-resistant crosslinked cable and flexible jacketing boasts a very high vinyl acetate content (40%) and a low MFI (less than 3), a difficult combination to achieve, according to the supplier, Arkema Inc., Philadelphia.
