Akcros Chemicals chooses K2001 to exhibit under Akzo Nobel banner for the first time

Akcros Chemicals BV : 01 June, 2001  (New Product)
Akcros Chemicals will be exhibiting under the banner of its parent company, Akzo Nobel, for the first time since mid-1998 when they agreed to purchase the remaining fifty-percent of the joint venture from its partner Elementis.
Akzo Nobel will be located in Hall 5, Stand 5A03 at K2001, the industry’s largest international triennial exhibition staged in Düsseldorf, Germany, from October 25 to November 1.

Akcros Chemicals, a pre-eminent name in the industry and one of Europe’s largest suppliers of polymer additives will be demonstrating its leadership in this field along with the Polymer Chemicals and Functional Chemicals businesses of Akzo Nobel thus promoting one of the widest product ranges of raw materials and additives in the international marketplace.

Offering one of the most comprehensive ranges of additives currently available, the Akcros product portfolio includes, stabilisers, lubricants, plasticisers, biocides, anti-static agents and rheology modifiers.

Akcros Chemicals' high performance polymer additives find widespread application in the manufacture and processing of PVC, polyolefins, polystyrene, ABS and other thermoplastic materials. In Europe, the company is one of the largest suppliers of additives to the PVC processing industry and the company is committed to expanding that leadership globally.

As a result of this commitment Akcros has pioneered many new technologies. These include:

Development of polymer additives in totally non-dusting, melt forms.

Rigid PVC stabilisation in form of one packs, free from lead, barium and cadmium.

Liquid mixed metal stabilisers with extremely low content of volatile solvents and of free phenol.

All of these innovations contribute to greater environmental acceptability. Moreover, Akcros additives, which can be tailored to specific application requirements, provide lubricity, heat and colour stability, UV and corrosion resistance, and increased resistance to ageing.

Akcros products have been developed for rigid PVC applications including pipes and ducting, window profiles, automotive profiles, furniture and building cladding, and for flexible applications such as packaging films, wire and cable sheathing, wall and floor coverings, fabrics and footwear.

The Akcros range includes a number of product groups, each of which comprises a family of individual products, enabling the formulator to select the characteristics necessary to meet his or her precise processing requirements. Key product groups include LANKROMARK, TINSTAB, INTERLITE, INTERSTAB, INTERCIDE, VULCABOND, LANKROFLEX, LANKROSTAT and INTERWAX.

LANKROMARK is a family of liquid mixed-metal heat stabilisers. They predominantly include barium-zinc and calcium-zinc stabilisers, as well as stabiliser/activators for PVC foams, and long established barium-cadmium-zinc products. The calcium-zinc range includes a number of 'low-toxic grades'. LANKROMARK stabilisers have been developed to give a wide spectrum of processing and end-use performance characteristics to meet the range of market requirements.

In both self-lubricating and non-lubricating forms LANKROMARK products find application in a wide range of flexible PVC products: from floor and wall coverings to coatings for tarpaulins. The low toxic calcium-zinc grades are used in processing materials for applications such as children's toys and food contact components.

A new addition to the range, to be highlighted at K2001, will be LANKROMARK LZB292. This is a barium-zinc liquid specifically designed for use in filled PVC formulations for floor coverings manufactured using the calendered process. Key benefits include very long thermal stability, low volatility and very low free phenol content thus providing significantly reduced odour during processing. In addition, LANKROMARK LZB292 delivers good colour hold in white pigmented compounds.

TINSTAB is a family of organotin stabilisers, mercaptides and carboxylates. These high efficiency heat stabilisers are optimised for both flexible and rigid PVC processing. From this group the formulator can select grades to exactly match application demands such as heat stability, colour holding and clarity, as well as grades with approval for inclusion in materials in contact with food. TINSTAB products can be used in all processing techniques: injection, extrusion, blow moulding and calendering. Their low rates of addition compared with other stabilisers make them very cost competitive.

VULCABOND products are direct bonding agents which improve the adhesion of PVC plastisols to polyester, nylon and other synthetic fabrics. The range was recently augmented by the introduction of VULCABOND KB, a product giving improved bond strength at a given level of addition.

INTERCIDE products provide protection for plastics against the effects of microbial attack. They are based on a number of active ingredients, which are formulated into a range of carrier materials, in different physical forms, to meet the wide range of processing and end-use performance requirements. INTERCIDE products find very wide use in flexible PVC, which is often susceptible to fungal attack due to plasticiser components of the formulation which act as food source, combined with warm moist environment in some end-use applications. Recently the company has extended its range to include biocides for other plastics. A recently launched addition to the range, IINTERCIDE DP8438F, is a solid product in granular form, designed for use in polyolefins to confer antimicrobial properties to the surface of the plastic. DP8438F is readily dispersible in LDPE and other polyolefin systems during processing.

Through the introduction of INTERSTAB and INTERLITE one-pack systems, a combination of stabilisers, lubricants and other additives, Akcros Chemicals has opened the way to simplify the processing of rigid PVC with their two product families INTERSTAB (mainly lead based one-packs) and INTERLITE (covering calcium-zinc and calcium-organic stabilisers. Both one-pack series meet the high performance requirements of rigid and selected flexible PVC applications, which include window profiles, other profiles, pipes, fittings, other injection moulded products, sheets, cables and floorings. Both product families can be delivered in low or non-dusting physical forms such as granules, flakes, tablets or agglomerated powders, as well as the standard powder form.

Offering similar rheological and physical properties as lead-based INTERSTAB systems, INTERLITE one-packs enable a change to a lead-free solution without any loss of efficiency and performance.

Akcros Chemicals has extended the range of Ca/Zn systems for pipes and fittings with new, more effective products as follows:

For Pipes and Fittings:

INTERLITE ZG 0229-serie for drainage pipes
INTERLITE ZG 0261/1 for corrugated electrical conduits
INTERLITE ZT 0271/1 for drinking water pipes
INTERLITE ZG 8501-serie for fittings (K-value 57-60 and 65)

The standard types for pipes can also be produced in tablet and flake form via the effective melt technology.

The first types of Ca/Organics (INTERLITE CG 0500-serie) are under evaluation and will be introduced at selected customers.

For Cables:

INTERLITE ZP/ZG 6095 is the latest Ca/Zn development for PVC cables in the automotive industry and is now fully approved according to DIN-ISO Standard 6722.

For general purpose cables INTERLITE ZG 6099 is providing excellent thermostability, colour-hold and good ageing properties .

For Window Profiles/General Profiles:

INTERLITE ZG 3249/1 ensures high extrusion speed and long extruder running times for the production of window profiles. INTERLITE ZG 4106 was introduced successfully for the high speed extrusion of thin-walled general profiles.
