Resin supplier LyondellBasell Industries AF SCA of Rotterdam, Netherlands, has announced a series of new materials.
* LyondellBasell has launched a family of butene-1 based polymers for elastic applications. Koattro resins are aimed at film, fiber, tapes, closure lines and aesthetic injection molding. They are highly compatible with polypropylene and improve that polymer's flexibility, transparency, impact resistance, tensile properties and stress-whitening tendencies.
The company combines softness at Shore A 70 hardness rating and a compression set of 45 percent that is nearly constant up to the melting temperature of 237°F.
Koattro plastomers are easier to regrind and recycle than conventional cross-linked plastomers, according to LyondellBasell. Automotive uses also are possible in areas such as dashboards, wire and cable and heat-resistant skins. Reduced stress whitening makes parts produced from the resins easier to install.

* The company has introduced a high density polyethylene especially well-suited to blow molded bottles.
Hostalen ACP 5231D provides a combination of optimized density, tailor-made stiffness, high environmental stress crack resistance and easy processability.
The firm claims the resin's ESCR is up to three times greater than a typical HDPE with the same density. LyondellBasell achieves high ESCR by a customized, multimodal molecular weigh distribution in its advanced cascade process.

* LyondellBasell has introduced a low-melt-flow rate propylene-based copolymer for extrusion blow molding.
Pristene RM2091 has a melt-flow rate of 3.5 grams per 10 minutes. It also has high transparency with only 2 percent haze in an injection molded plaque vs. 6-10 percent haze for previous resins. It also provides high clarity to stiffness balance, according to the firm's global metocene business unit in Wilmington, Del.
RM2091's high-melt stability makes it suited for applications requiring intricate design such as clear handles in extrusion-molded bottles. Its high clarity and stiffness make it a potential replacement for amorphous transparent polymers including polycarbonate, vinyl and glycol-modified PET. LyondellBasell said the new material does not require pre-drying or high processing temperatures.
