HEXPOL TPE present advances in TPEs for appliance, construction and consumer markets at Plastpol 2016


Following a successful show in 2015, international compounding group HEXPOL TPE will again be exhibiting at Plastpol in May. At this year’s expo they will showcase progressive TPE solutions for the construction, appliance and consumer markets.

The household appliance sector continues to be an important market for Poland, here HEXPOL TPE has developed a number of TPS and TPV based compounds for applications such as vacuum cleaners, refrigerators and consumer electronics.

Dryflex V thermoplastic vulcanisate (TPV) compounds are being used for sealing in clothes dryers where there are requirements for high service temperatures and resistance to fluids. Dryflex V compounds have been designed to retain compression set and dynamic sealing properties over long periods of time and at elevated temperatures. Grades are available with low viscosity and high-flow properties for injection moulded sealing applications with long and complex flow paths.

Among the solutions HEXPOL TPE will present for the construction market will be the Dryflex PS range of TPE compounds for seals and pipe joints used in waste water applications. The Dryflex PS grades meet the requirements of EN 681-2:2000, the European Standard EN 681-2, Type WT.

The EN 681-2:2000 standard specifies requirements for TPE materials used for moulded seals used in joints of:

1. Thermoplastic piping systems for non-pressure waste water discharge (intermittent flow up to 95°C) inside buildings

2. Thermoplastic piping systems for non-pressure underground drainage and sewerage (continuous flow up to 45°C and intermittent flow up to 95°C)

3. Thermoplastic rainwater systems

Dryflex PS - TPE for pipe seal applications
For the consumer market, soft-touch overmoulding technologies and materials continue to enhance design possibilities. They have allowed for the introduction of tactile and non-slip features and expanded colour, texture and functional options. At Plastpol, HEXPOL TPE will present advances in thermoplastic elastomers for overmoulding as well as new options with biobased TPE compounds.

For the producers of multi-component applications, it is critical that the parts do not display poor adhesion of the TPE and substrate, which can result in delamination and peeling of the TPE layer. Not all materials are compatible and the chemistry of both the TPE and substrate needs to be considered. Initial overmoulding technologies primarily combined a rigid PP substrate with a compatible olefin based TPE. However with the expansion of multi-component designs into new application areas, the demand for TPE compounds that give a cohesive adhesion to a wider range of substrates arose. HEXPOL TPE offer a range of TPE compounds based on different chemistries (for example TPO, TPS and TPV), with grades offering adhesion to a variety of substrates including PP, PE, PA, ABS, PC, PS, PMMA, ASA, SAN and their blends.   

Of particular interest at Plastpol will be the Lifoflex range of TPE compounds for overmoulding with Polyamide (PA) which are being used in applications such as power-tools. The range includes grades offering a high bonding strength to PA6, PA66, PA12 and PA blends including reinforced polyamide with up to 40% glass fibre. The compounds can be processed via insert and multi-shot processing technologies. Due to the wide processing window from 200°C to 280°C, they have a high bonding strength to the different polyamide types.

TPE for PA overmolding

One of the latest additions to the HEXPOL TPE portfolio is the Dryflex Green family of TPE compounds containing raw materials from renewable resources such as plant and vegetable crops. Several series are available with amounts of renewable content to over 70% (ASTM D 6866) with hardnesses from 50 to 80 Shore A. Dryflex Green TPEs display mechanical and physical properties comparable to TPE compounds from fossil based raw materials. They can be processed using traditional polymer technologies such as injection moulding and extrusion. Dryflex green TPE compounds offer adhesion to polymers such as PE, PP, ABS and SAN for 2K and multi-component applications.

Dryflex Green TPE compounds have the potential to be used in many applications that currently use conventional TPE compounds such as soft-touch grips and handles, packaging, sports equipment, toys and infant care.

Peter Ryzko, managing director at Müller Kunststoffe, the German arm of HEXPOL TPE commented, “We are delighted to be back at Plastpol this year. Poland is an important market for us where we see interesting growth in a number of market sectors. We are proud to present the extent of materials and services offered by HEXPOL TPE to support our Polish and CEE customerbase.”

HEXPOL TPE is exhibiting at Plastpol 2016 in Kielce, Poland at STAND N69 from 17 - 20 May.
