Sylvin compounds have FDA approval
Sylvin Technologies Inc. has new flexible vinyl compounds for markets where Food and Drug Administration acceptance is required.
The Denver, Pa., firm's new 2900 series incorporates only ingredients sanctioned for use by the FDA. The grades are available in hardness from 55 Shore A to 90 Shore A.
Grades are in standard clear formulations that can be custom colored. Sylvin said they are well suited to injection molded and extruded products such as appliance parts, tubing and conveyor belting.

Sunoco Chemicals PP for film applications
Sunoco Chemicals has debuted a homopolymer polypropylene especially suited to film applications.
FF025F has high amorphous content to give it exceptional stretchability, according to the firm. The product is an all-purpose grade that complements Sunoco's lineup of films with a range of melt flows useful for biaxially oriented PP and for cast film use.

Dow olefins free from confidentiality pacts
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 processability 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 process 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.

Invista's PET includes 20% recycled content
Invista has developed a PET packaging resin that contains 20 percent post-consumer content.
The Wichita, Kan., firm said the new Polyclear Conserve PET resin features exceptional color and clarity. It avoids contamination because the recycled content is repolymerized so that it acts as virgin polymer. The material is not simply a blend of reground recycled flake with virgin resin.
Invista said the material is suited to container applications including bottled water and soft drinks. It complies with the Federal Food, Drug and Cosmetic Act for certain food-contact use.
The company said it is working to increase the post-consumer content of Polyclear Conserve PET.
