K2022 PREVIEW | MATERIALS
Right: Kraiburg’s PIR TPEs contain up to 38% recycled content and meet automo- tive interior requirements
ester lubricants and slip agents, which can be used with many commodity and engineering resins. Palmowax EBS and Palmester 3976 are said to
promote low surface friction and easy release in finished plastic parts produced by calendering, extrusion and injection moulding. Palmowax EBS is also useful in production of masterbatches, where it can act as a pigment dispersant as well as a processing aid that lubricates and homogenises other additives in the melt mixing system. �

Kraiburg TPE will focus its display on its latest sustainability solutions, including TPE products with both post consumer and post industrial recycled content. RC/UV TPE grades carry 20-40% of post indus-
trial recycled material and are said to meet auto- motive OEM requirements for weathering resist- ance and high surface quality in exterior parts. Interior PIR TPEs are also aimed at automotive applications, containing up to 38% post industrial recycled content. For the consumer and general industrial
applications, Kraiburg’s Universal PCR TPE prod- ucts can be formulated with up to 41% post consumer recyclate. The compounds are available in natural or grey and can be coloured as required. Mechanical performance is similar to virgin grades. �

Kuraray will introduce its Bio-Circular ethylene- vinyl alcohol (EVOH) at K2022, the latest addition to its line of Eval EVOH barrier resins for packaging applications. The company says it is the first EVOH copolymer
producer to receive ISCC Plus certification for bio-circular ethylene monomer in its supply chain. It says it covers, in principle, all EVOH variants that it produces at its plant at Antwerp in Belgium. Kuraray will also show its Septon Bio series of

TPEs, which are based on hydrogenated styrene farnesene block copolymers (HSFC) synthesised from beta-farnesene, a monomer derived from sugarcane. Bio-based content varies up to 80% depending on the specific grade. Compared to conventional styrenic block copolymers, Septon Bio grades are claimed to reduce greenhouse gas emissions by up to 33% as well as improving properties such as oil retention, weatherability and compression set. Kuraray will also show a high pressure hydrogen tank design developed for fuel cell vehicles using a carbon composite based on its Genestar PA9T polyphthalamide resin. Widely used in automotive under-hood applications such as thermostat housings or high-voltage connector, Genestar is said to stand out among high temperature PA resins for its low moisture absorption, which ensures high dimensional stability. �

Lanxess will be focusing on developments for the e-mobility sector, including new materials for high voltage connectors, a PA6 material for on-board battery charging, and its latest heat-stable color- ants and flame retardants. Designed for production of high voltage EV connectors, Pocan BFN HR is a new halogen-free flame retarded PBT providing good hydrolysis and temperature resistance along with a 600V CTI rating and dielectric strength in excess of 30KV/ mm at up to 140°C. “One strength of the structural material is that its outstanding electrical properties are hardly dependent on temperature and moisture in the typical operating conditions of high-voltage connectors. It can be used at temperatures of up to 150 °C,” says Dr Bernhard Helbich, Technical Marketing Manager Key Accounts in the company’s High Performance Materials business unit.
