Munich, May 8, 2012 – At PLAST 2012, WACKER, the Munich-based chemical group, will showcase novel silicone rubber grades for manufacturing pacifiers and bottle nipples for infants and toddlers. These new grades include two liquid silicones of the ELASTOSIL® LR 3040 product line and two ELASTOSIL® R plus 4020 solid silicones. An outstanding feature of all four products is the high – and in the case of the two solid silicone rubber grades extraordinarily high – tear strength of the cured rubber. The PLAST tradeshow will take place from May 8-12 in Milan, Italy.
The innovative liquid silicone rubber grades target the fast production of soft yet bite-resistant silicone pacifiers and bottle nipples. They extend the ELASTOSIL® LR 3040 product line by two grades that cure to form elastomers with a Shore A hardness of 30 (ELASTOSIL® LR 3040/30) and 45 (ELASTOSIL® LR 3040/45). With these hardnesses, WACKER fulfills a wish often expressed by manufacturers of infant and toddler products.
After curing, ELASTOSIL® LR 3040 exhibits a tear strength which is significantly higher than that of comparable liquid silicone rubber grades. Pacifiers and bottle nipples made of the new liquid silicone rubber grades thus also endure the strains produced by children’s baby teeth, for example. Like all ELASTOSIL® LR 3040 grades, the two new liquid silicones feature very short curing times.
The cured products of the two ELASTOSIL ® R plus 4020 solid silicone rubber grades exhibit even higher tear strength – over 50 newtons per millimeter, measured as per ASTM D 624 B. Until now, such values were unattainable with silicones in baby care applica-tions. ELASTOSIL® R plus 4020 enables the manufacture of thin-walled and compliant pacifiers and bottle nipples which, at the same time, exhibit practical bite resistance. Low wall thicknesses make for greater freedom of design and facilitate the manufacture of ortho-dontically correct pacifiers and bottle nipples. The two grades extend the product line by the hardness levels most often used for pacifiers and bottle nipples, Shore A 40 and 50 respectively.
All four new silicone rubber grades can be processed by injection molding. They produce highly transparent cured rubber with excellent mechanical properties. The post-cured rubbers are food-compatible and meet the requirements of the Federal German Institute for Risk Assessment (BfR), the US Food and Drug Administration (FDA) and the French Arrêté du 25 novembre 1992.
Thanks to these innovative grades, the product lines of liquid and solid silicone rubbers with particularly high tear strengths now include a practical range of hardness levels: ELASTOSIL® LR 3040 covers hardnesses between Shore A 30 and 60, while ELASTOSIL® R plus 4020 is available in Shore A hardnesses of 40 to 70.
