Si-TPV Silicone based thermoplastic elastomer VS Silicone, who is the better material for cell phone cases?

describe:

The types of soft plastic materials are mainly distributed in the rubber and plastic, thermoplastic plastic class, but nowadays many accessories accessories and life with soft plastic material instead of and occupy a large number of decorative products market, which use more belong to the number of silicone products and TPU these two materials, no matter in the electronic products as well as general decorative products, silicone materials and Si-TPV Silicone based thermoplastic elastomer are very popular. Si-TPV Silicone based thermoplastic elastomer are very popular, and these two materials compared with other thermoplastic materials, more emphasize the safety and environmental protection of the product, so what are the differences between them in the end?

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 silicone-based thermoplastic elastomers can be widely used in the field of 3C electronic materials. In addition to being used as general cell phone cases, they can also be used as soft touch overmoulding on smartphones/soft touch overmoulding on portable electronic It can also be used as soft touch overmoulding on smartphones/soft touch overmoulding on portable electronic cases, replacing Silicone overmolding, and it can also replace soft PVC to meet the environmental protection requirements in more and more fields.

At present, many soft material supplies have chosen to use this type of rubber to replace, but compared with silicone their differences lie in various aspects of performance above the different advantages and disadvantages, and strictly speaking Si-TPV silicone-based thermoplastic elastomers are more widely used, due to its hardness range is wider than the silicone, so with the hardness of the different role of the different ranges are also different.

The chemical composition and physical structure of silica gel determines that it has many other similar materials difficult to replace the characteristics: high adsorption performance, good thermal stability, chemical stability, high mechanical strength. Silicone according to the size of its pore size is divided into: large pore silicone, coarse pore silicone, B-type silicone, fine pore silicone.

There are two main types of silicone covers known at present, one is organic silicone and the other is inorganic silicone. Currently marketed digital products silicone cover basically belongs to the organic silicone. It has high temperature resistance, trespassing resistance (not afraid of ultraviolet light or ozone decomposition), good insulation, material stability and other characteristics.

Advantages: cheap, high adsorption performance, good cushioning performance, not easy to wear and tear, more comprehensive protection.

Disadvantages: thick texture, fewer styles, easy to grease, and body fit is slightly worse, while the material is slightly poorer is also easy to stain the ash and dust into the ash!

Silicone case itself is slightly sticky, after a period of time will adsorb a lot of dust on the phone, in the long run, but not conducive to the beauty of the phone, and the protection of the phone’s original purpose of the contrary!

Si-TPV silicone-based thermoplastic elastomer has the following outstanding properties: Long-term silky skin-friendly comfort soft touch Materials: Si-TPV Silicone based thermoplastic elastomer has excellent and long-lasting skin-friendly comfort soft touch, which can be obtained without touch treatment, and does not contain harmful substances such as phthalic acid. It does not contain harmful substances such as phthalic acid, and there is no need to worry about problems such as stickiness and coating peeling off due to feel treatment. It is an Extremely silky feel material without Additional Coating/High Tactile TPU Compounds/Sustainable Elastomeric Materials. Soft elastic material: Si-TPV Silicone based thermoplastic elastomer has good elasticity and softness, which can protect the cell phone well from damage caused by collision or fall. Better wear-resistant material: Si-TPV Silicone based thermoplastic elastomer has high strength and wear-resistant, not easy to be deformed and damaged, with good loading capacity, impact resistance and shock absorption, it is able to withstand greater deformation and damage, and can provide a more long-lasting use experience.
Non-tacky Thermoplastic Elastomers: Si-TPV Silicone based thermoplastic elastomer has the excellent property of long-lasting non-precipitation, long time use without oil and non-stick. Skin safety comfortable waterproof material: Since Si-TPV Silicone based thermoplastic elastomer has good waterproof performance, it is very suitable for protecting cell phones with excellent anti-sweat performance. Customized material: Si-TPV Silicone based thermoplastic elastomer is easy to process, can be processed by injection molding, extrusion and other molding processes, easy to take off the mold, high customization, can be made into various colors and styles according to different needs. Si-TPV Silicone based thermoplastic elastomer is a kind of Dirt-resistant Thermoplastic Elastomers, Dirt-resistant Thermoplastic vulcanizate Elastomers. Innovations, easy to clean, with excellent elasticity, abrasion resistance, durability, waterproof and other properties, it is a very practical material for cell phone cases.
