DUESSELDORF, GERMANY—Momentive Performance Materials Inc. will introduce new silicone technologies, including a new self-bonding liquid silicone rubber, during the K 2019 rubber and plastic trade show in October.
On display will be Momentive's complete portfolio of Silopren LSR, including the new self-bonding Silopren LSR 27×9 family, which offers primerless adhesion to PC, PBT and copolyester substrates in commercial hard-soft combinations.
The product addresses the rising demands for hard-soft designs, helps achieve the bonding between silicone and thermoplastics and reduces assembly steps, Momentive said Aug. 5.
At K, the company will conduct a live demonstration of a two-component molding cell, manufacturing a butterfly smartphone holder prototype. This cell will overmold a plastic frame, based on Covestro's Apec 1745 polycarbonate, directly in a second shot with the new Silopren LSR 2759 from Momentive. The result will be a smartphone holder with primer-less adhesion between the PC and silicone rubber, which is designed to be attached to a car´s ventilation flap, Momentive said.
The entire demo design, set up and implementation will be provided by Elmet, which also built the two-shot mold, automation and LSR dosing system TOP 5000 P.
Setup will be implemented on a two-component injection molding 'SmartPower 120' machine and robot from Wittmann-Battenfeld.
K 2019 will take place Oct. 16-23 in Duesseldorf, Germany.
