Si-Tpv Overmolding Lightweight: A More Comfortable Choice for Handlebars

describe:

The handlebar, as the most touched part of the bike, carries the important function of handling and driving the bike, and the first comfort level of a bike is also brought by the handlebar. A suitable handlebar material will be related to the comfort of riding and cycling enthusiasts on the degree of love of the bike. Bicycle/motorcycle handlebars are usually made of soft rubber handlebar covers to provide a soft touch and non-slip effect, but in practice, problems such as sticky handlebars are often encountered. Si-TPV Overmolding Solutions provides a more comfortable and ergonomic choice for handlebars.

Overmolding Techniques & Adhesion Requirements

SILIKE Si-TPVs Overmolding can adhere to other materials through injection molding. suitable for insert molding and or multiple material molding. Multiple material molding is otherwise known as Multi-shot injection molding, Two-Shot Molding, or 2K molding.

SI-TPVs have excellent adhesion to a variety of thermoplastics, from polypropylene and polyethylene to all kinds of engineering plastics.

When selecting an Si-TPV for an over-molding application, the substrate type should be considered. Not all Si-TPVs will bond to all types of substrates.

Application

Si-TPV soft over-molded material is an innovative way for manufacturers who produce hand grip， they need unique ergonomics as well as safety and durability.

Sticky handlebars present more than a mere annoyance, they pose tangible safety risks on the road or trail. The causes of this stickiness are multifaceted, involving exposure to the elements and the natural effects of daily use. Particularly, sunlight significantly contributes to the breakdown of the rubber material of handlebar grips over time. Furthermore, the natural perspiration of hands during rides adds to the accumulation of moisture on the grip’s surface, fostering a sticky residue when combined with dirt, grime, and road dust, thus compromising the riding experience.

Innovative Solutions: A range of innovative solutions exists to address this stickiness and maintain handlebars in prime condition: ✨Material Selection: Opt for materials that offer a naturally soft and tactile feel, such as Si-TPV, silicone rubber, thermoplastic elastomers (TPE), and specific types of foam. These materials not only provide a pleasant texture but also resist stickiness, ensuring a clean and comfortable grip. ✨Ergonomic Design: Develop grips with ergonomic shapes that fit comfortably in the user's hand, reducing strain and discomfort during use. ✨Surface Texture: Integrate subtle surface textures that enhance grip and prevent slipping, such as micro-patterns or gentle contours.
✨Cushioning: Incorporate cushioning layers within the grip to offer a soft yet supportive touch, absorbing vibrations and shocks for an even more comfortable ride. ✨Addressing Sweat and Sebum Resistance: Implement strategies to resist sweat and sebum, such as hydrophobic coatings, oil-resistant formulations, and sealed designs, along with educating users about proper cleaning and maintenance routines. At SILKE, we are dedicated to pushing the boundaries of the handlebar and hand grip material, offering versatile elastomers for sporting goods, resistance against sweat and sebum, and aesthetic grips. Our Si-TPV materials provide a silky, skin-friendly touch that resists stickiness, ensuring a clean and comfortable grip every time.
