Preparation method of Soft Eco-friendly Electric Toothbrush Grip Handle
>>Electric toothbrushes, the grip handle is generally made of engineering plastics such as ABS, PC/ABS, in order to enable the button and other parts to directly contact the hand with good hand feeling, the hard handle is generally encapsulated by soft rubber, the common soft rubber is TPE, TPU or silicone, that the attractiveness and the hand feeling of injection products can be improved.
But, silicone or other soft glues are used and combined with engineering plastics in a glue bonding mode, The steps are complex, the uncontrollable performance is high, continuous production is difficult to achieve practically, and during the practical test, the glue can be hydrolyzed under the effects of toothpaste water, mouthwash or face cleaning product, that the soft and hard glue is easy to degum.
However, Si-TPV is used for injection molding on engineering plastics for electric toothbrushes grip handles. and the injection products can be continuously produced.
the obtained product keeps the binding force under a weak acid/weak alkaline environment(toothpaste water), it is not easy to peel off, as well as, retaining the aesthetic appeal of the injection grip handle. unique soft-touch, stain-resistant.
