Dow Chemical Co. has nine developmental-grade olefin block copolymers that no longer are tied down by confidentiality agreements.
To be marketed under the Infuse tradename, they are made using Dow's Insite technology, which enables olefins to expand into elastomeric markets.
The olefin block copolymers are suited for several markets.
For soft-touch use, they offer processing efficiency and excellent adhesion in overmolding, the company said.
Polyolefinlike proc¼essability suits the block copolymers for health and hygiene uses where high-performance elasticity, cohesion and adhesion at body temperature are key.
They are particularly useful in elastic films and elastic nonwovens, according to Dow.
In liquid packaging they proc¼ess well without the use of oil and exhibit excellent seal properties and organoleptic characteristics, said Dow of Midland, Mich. The grades also find use in adhesives.
Dow's new products variously have a melt-flow index of 0.5 gram to 15 grams per 10 minutes.
