Detail

SILIKE focuses on Innovative Soft Slip Technology to develop Soft skin-friendly comfort Elastomeric Materials for haptics to enhance the user experience when wearing and operating AR and VR products. Since Si-TPV is a lightweight, long-term extremely smooth, skin-safe, stain-resistant and environmentally friendly material, Si-TPV will greatly enhance the aesthetics and comfort of products. In addition, Si-TPV offers design freedom, perfect adhesion to polycarbonate, ABS, PC/ABS, TPU and similar polar substrates without adhesives, colorability, overmolding, no odor, unique overmolding possibilities and much more. Unlike traditional plastics, elastomers and materials, Si-TPV has an excellent soft touch and requires no additional processing or coating steps!

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.

For more information regarding specific over-molding Si-TPVs and their corresponding substrate materials, please feel contact us.

Application

Soft skin-friendly comfort material for wearables in the AR/VR field Si-TPV soft elastic material for AR/VR can be made into skin-friendly masks, head straps, wrapping rubber, mirror leg rubber covers, nose parts or shells. From processing performance to surface performance, from touch to texture, multiple experiences are fully upgraded.

Si-TPV Soft elastic material/Thermoplastic Elastomers is called Si-TPV dynamic vulcanizate thermoplastic Silicone-based elastomer, a special material that is fully vulcanized by means of a special compatibilizing and dynamic vulcanizing technology. This special material is made by special compatibility technology and dynamic vulcanization technology to fully vulcanized silicone rubber with 1-3um particles uniformly dispersed in a variety of substrates, forming a special island structure, both low hardness of silicone rubber, high and low temperature resistance, chemical resistance, high resilience and the advantages of the substrate, with a high degree of physical compatibility and good resistance to contamination, so it can provide first-class performance and flexibility of processing, and is widely used in footwear, wire and cable, films and sheets, AR/VR, and other industries. It is widely used in footwear, wires and cables, films and sheets, and AR/VR soft contact materials.

The key to Si-TPV Soft elastic material’s versatility is its wide range of hardnesses, as well as its appearance and texture, which allows for a variety of textured surfaces as well as a high level of matte texture without treatment.

Si-TPV Soft elastic material features： ● long-term silky skin-friendly comfort soft touch Materials/ Non-tacky Thermoplastic Elastomers: Si-TPV Soft elastic material has a long-lasting skin-friendly touch, non-sticking. Safe, anti-bacterial and anti-allergic, free of plasticizers and other harmful substances, also a Phthalate-Free Elastomeric Materials ● TPU with Improved Frictional Properties: excellent load-bearing capacity, impact resistance and shock absorption properties, high mechanical strength, wear-resistant and scratch-resistant. ● Skin-friendly soft overmolding materials: excellent overmolding performance, can be very good with ABS, PC/ABS and other materials for overmolding, good adhesion, not easy to fall off;
● Softer TPU: wide range of hardness, Shore A 35~Shore A 90: by changing the ratio of each reaction component of TPU, you can get different hardness products, and hold a good resilience, abrasion resistance and skin-friendly touch. ● Good color saturation, bright colors, a wider range of choices. ● TPU for Improved Handling: good processing performance, can be manipulated more, you can use the common thermoplastic materials processing methods for processing, such as injection molding, extrusion and so on. ● Dirt-resistant Thermoplastic Elastomers: oil-resistant, water-resistant, sweat-resistant, dirt-resistant, weather-resistant, yellowing-resistant, good regeneration and utilization, can be recycled for the second time, safe and low-carbon environmental protection.
