 of new additive concentrates for polyolefins will be featured by Ampacet Corp., Tarrytown, N.Y.:

* PE concentrate 101950 UVA contains Shelfplus UV, the new uv filter from Ciba Specialty Chemicals “Ciba” redirects here. For the pre-1971 company, see Novartis.

Ciba Specialty Chemicals is a chemical company based in and near Basel, Switzerland. It was formed as the non-pharmaceuticals elements of Novartis were spun out in 1997, following the merger in the
. This additive is said to outperform other uv absorbers in that it can block 90% of light up to 390 nm wavelength. Its lack of color not of the white race; - commonly meaning, esp. in the United States, of negro blood, pure or mixed.

 bottles. A PET concentrate of Shelfplus UV for PET bottles is in development.

* Product 101501, a non-migrating slip-additive concentrate for blown film, is said to be based on a unique alternative to the usual oleamide or erucamide. It produces an immediate reduction in coefficient of friction coefficient of friction
n. pl. coefficients of friction
The ratio of the force that maintains contact between an object and a surface and the frictional force that resists the motion of the object.
 (COF) that will not change over time. It will yield a COF of 0.3 when used at a 10% level. Because of the higher-than-normal loading, it performs best in the skin layer of multilayer structures, but it is acceptable for food contact, according to Ampacet.

* Also non-migrating is a new antistat concentrate for non-food uses. Ampacet says Product 101710 is based on totally new chemistry. It is most effective at use levels of 30-40% and is thus best suited to the skin layer of multilayer structures.

* Ampacet has two new products for thin (1-micron) skin layers of multilayer BOPP films. SAT062, which is both an antiblock and hot-slip agent, is designed for cigarette packaging film. At 5-7% usage in a skin layer, it can achieve film/film COF of 0.2 at 70 C and film/metal COF of 0.3 at 70 C.

* Seablock43 SAT, touted as a new type of antiblock masterbatch, is said to be an unusual combination of organic particles in a new PP terpolymer ter·pol·y·mer

 vehicle. The terpolymer is used for films that require very low seal-initiation temperature and good hot-tack properties. The additive reportedly provides COF reduction, good antiblocking properties, and excellent optical properties in the terpolymer films. Because its ingredients are nonmigrating, the concentrate can be used in metalized films. Typica1 use level in the skin layer is 3-5%.

* Product 101802 is a film processing-aid masterbatch consisting of 70% mineral particles in a low-melt-index LLDPE LLDPE Linear Low Density Polyethylene  carrier. At 25-30% use levels, it significantly boosts film properties including a 30% increase in dart impact, 30-40% increase in flex modulus, and 20% decrease in MVTR MVTR Moisture Vapor Transmission Rate

. Recent field trials have demonstrated 20% higher linear throughput.

* Ampacet will also feature a new series of 50% antiblock concentrates in PE carriers with combinations of slip, uv, and processing aids, as well as a line of additive concentrates for use with acid copolymers and their salts.
