Solvay has developed a biodegradable thermoplastic designed to be easily blown into film using standard equipment.

Based on Solvay’s Capa polycaprolactone, the material has good appearance and maintains its mechanical properties in the presence of moisture.

The new Capa polycaprolactones are polyesters obtained through a state-of-the-art manufacturing process. They are easy to process with normal thermoplastic processing techniques, easily welded and printed, and can be converted in a wide variety of forms.

CAPA products are used in a diverse range of performance applications in various industries, including automotive, aerospace, electronics, health and shoes.

Higher flow elastomers

Two high-performance Engage polyolefin elastomers designed to meet higher flow and enhanced cold temperature impact requirements are now available from DuPont Dow Elastomers.

The new 8842 grade offers exceptional properties of ultra-low density elastomers. It is a 1 melt index, 0.857 g/cc ethylene-octene co-polymer.

To enhance flow properties, Engage 8130 is a 13 melt index, 0.864 g/cc ethylene-octene co-polymer. This grade allows thinwalling of parts and offers improved processability.

Cable compounds use dioxin-free FR

New peroxide-curable, flame-retarding insulation compounds for 600-volt power and control cables have been developed by Equistar Chemicals.

Petrothene XL 07633 and XL 04711, which use non-dioxin forming, halogenated flame retardants, have superior electrical and heat-age properties.

Both products use the latest technology processing aids to minimize the die drool that causes the “horse collar”.

TPU cuts cycle time

Bayer Corp. has improved its Texin thermoplastic polyurethane resins to cut injection molding cycle time by as much as 30 percent.

The fast-cycle grades are available in a variety of hardness ratings and properties.

One customer that participated in field tests of the new resins produces millions of animal identification tags each year. Temple Tag cut its injection molding cycle time by 14 percent with the new Texin DP7-1158, and the new formulation has a lower specific gravity so product yield increased by two percent.
