MINERALS Trinity offers talc alternatives

Trinity Resources of Canada has introduced two new mineral reinforcing fillers based on pyrophyllite (hydrous aluminium silicate). Altiplus and Altibright are being marketed as alterna- tives to talc and kaolin. The company says that the

pyrophyllite fillers are macrocrystalline platelets with a high aspect ratio and the same monoclinic crystal structure as talc. They are produced from a large deposit located in Conception Bay South, Newfoundland, Canada.

The mineral’s properties

are said to include high dry and wet brightness thanks to their low levels of iron oxide and other mineral impurities. The excellent optical properties of Altiplus and Altibright makes them ideally

BIOCIDES Fast acting, durable antimicrobial masterbatch

Safe-Touch is an antimicrobial masterbatch from US-based PolyFusion that is claimed to provide fast action and long active life-time. It is based on organo-functional silane technology. According to the company,

when evaluated in accordance with the ASTM E2149:10 dynamic contact protocol, it requires a one hour test timeline compared with 24 hours for ion exchange and phenol-based products. CFU reductions of 99.99% are said

to be typical when using the additive at 1-2% loading levels. PolyFusion says the

Safe-Touch product is available as a pellet or powder and is compatible with most com- modity and engineering polymers. No special handling

precautions or process changes are required. The company adds that it

is targeting the additive at thermoplastic applications where control of environmen- tal bio-burden is paramount. ❙

January 2013 | COMPOUNDING WORLD 57 Altiplus is a bright mineral with a high aspect ratio

ated with subtle plays of colour. The new products include Apocalyptic Purple, Passion Crush, Machined Green, Hush

Hush Gold, Shadowed Brown and Blued Mood. Linda Carroll, Ampacet’s Color Insight manager, says:

“There’s a new colour story on black that embraces changeability and mystery”. ❙


Gabriel set to tackle forgers

suited for natural and colour sensitive systems, says the company. In addition, the additives are

said to provide high levels of stiffness, impact and dimen- sional stability together with chemical resistance, thermal stability and low electrical conductivity.

Altiplus grades are supplied in sizes ranging from 2 to 10 micron median, while the Altibright grades with 95-96 Y brightness values come in 1 and 2 micron median sizes. Target applications include com- pounds based on polyolefins, TPOs, TPEs and nylons. Distributors have been

appointed in Canada, the USA and northern Europe with additional agents being sought for other territories. ❙

Gabriel Chemie has launched a new additive masterbatch that is designed to combat the counterfeiting of thermoplastic products. Its Maxithen ProTec4 contains individual codes in the form of security pigments that can be verified using a special detector. It is possible to use

different codes for different manufacturing runs. This can be used for quality control purposes or to protect manufacturers against false compensation claims. Gabriel Chemie describes the security pigments as inert, inorganic, and highly temperature resistant substances. ❙
