ExxonMobil Chemical introduced Wednesday a new version of Santoprene thermoplastic vulcanizate (TPV) that complies with Food and Drug Administration regulations for food contact and bonds with engineering thermoplastics (ETPs).
In a press releease, the company said the new grade is suitable for many types of applications which come into contact with food and liquids, including kitchen utensils, cutlery, blenders and processing equipment, food storage containers, small kitchen appliances such as toasters, kettles and microwaves, and caps, seals and closures.
Santoprene TPV B100 is designed for adhesion to acrylonitrile butadiene styrene (ABS), polycarbonate (PC), polystyrene (PS), acrylic (PMMA), acrylonitrile styrene acrylate (ASA), polyethylene terephthalate (PET) and polyphenylene oxide (PPO)/PS blends using cold insert, two-shot injection or extrusion molding.
The company said Santoprene TPV B100 provides greater design flexibility and helps reduce the number of manufacturing steps. Because it adheres directly to ETPs during processing it can reduce the need for multiple-component assembly, improving product development cycle times and lowering system costs, ExxonMobil Chemical said.
Santoprene specialty products are recyclable elastomers commonly used in appliance, automotive, consumer goods, plumbing, and other applications.
