Exxon adds stiffness with new HMW HDPE
Exxon Chemical Co.'s new high- molecular-weight, high density polyethylene provides enhanced stiffness in heavy-wall bags and other packaging.
Escorene HD7845 can be processed on conventional linear low density PE extruders and is compatible with a wide range of other PE resins.
Houston-based Exxon said the resin is popular for blending with its Exceed metallocene LLDPE to produce film with high clarity and stiffness.
Escorene HD7845 has a melt index of 0.45 gram per 10 minutes and density of 0.958 gram per cubic centimeter.

Elf Atochem offering extrusion compound
Elf Atochem North America Inc. has commercialized a new Kynar Flex polyvinylidene fluoride extrusion compound with higher melt temperature and better low-temperature ductility.
The Philadelphia-based company said its Kynar Flex 3120 is available in two grades. One is a high-viscosity type with no additives and enhanced melt strength. The other is a low-viscosity, fire-retardant material that is easy to process for wire and cable uses.

Ticona introduces stronger polyolefins
Ticona has debuted two long-fiber-reinforced polyolefins for blow molding and extrusion with greatly enhanced strength properties.
Celstran PEHD-GF-50-02 is a high density polyethylene. With 10 percent long-glass-fiber content, the material offers flexural modulus of 220,000 pounds per square inch, tensile strength of 3,800 psi and notched Izod impact strength of 2.3 foot-pounds per inch.
Celstran PP-GF-50-05, a polypropylene, has room temperature flexural modulus of 310,000 psi at a 10 percent glass content. That material's tensile strength is 8,500 psi and notched Izod impact is 1.6 foot-pounds per inch.
The materials contain glass fibers about 11 millimeters long that are typically available with glass loadings of 5-50 percent, according to the Summit, N.J., subsidiary of Hoechst AG.

ABS grade fostering global consistency
BASF Corp. is introducing new standard grades of ABS resin that it claims will help customers get more-consistent properties around the world.
The Mount Olive, N.J., firm said five new Terluran ABS grades include GP-35, with very high flow and stiffness for injection molding, HI-10, with medium flow and very high impact strength, and Terluran EHI-5, a very high impact type suited for coextrusion.
BASF is building a new ABS plant in Altam¡ra, Mexico, due to come on stream in the first half of 1999. The firm said the facility will serve the North American Free Trade Agreement region and will provide products consistent with plants in Ludwigshafen, Germany, and Ulsan, South Korea.

MicroTech develops masterbatch pellet
MicroTech Research Inc. has developed a masterbatch pellet that it says can be extruded with any conventional resin to make biodegradable film.
The company has patented the masterbatch, dubbed the Elevate Culfree Microorganism.
According to MicroTech Research, the product is activated by heat and moisture to start microorganism growth that will eat the plastic until it is totally consumed.
MicroTech Research is based in Mentor, Ohio.
