Teknor Apex has developed a new series of styrenic thermoplastic elastomers (TPEs) with the surface appearance and haptics of silicone rubber.
Monprene RG-15100 series compounds have lower compression set than standard TPS (styrenic thermoplastic elastomers) compounds and withstand temperatures in excess of 100 °C, said Teknor Apex 11 Dec.
The materials also provide chemical resistance for food-grade, cosmetics, and other regulated applications.
The new compounds, said Teknor Apex, meet US and EU regulations for single- and repeated-use applications with dry, acidic, aqueous, and alcoholic food types.
“Pre-compliance with regulations accelerates our customers’ speed to market with new products,” said Christopher Smith, senior market manager for the TPE division of Teknor Apex.
The materials' Shore A hardness ranges from 30 to 80, and all grades are translucent.
The compounds are suitable for injection moulding and extrusion applications such as utensil grips; kitchen appliance seals; food-saver container seals; dropper bulbs; and cosmetics applications. They can also be used for microwave- and dishwasher-safe containers.
Furthermore, the compounds “may be” two-component moulded with polyolefins, Teknor said.
In addition to standard grades, Teknor says it is prepared to develop custom formulations, that meet regulatory requirements, for its customers.
