KIREI REZA® silicone leather is widely used in the field of electronic accessories, mobile phone cases, earphones, PAD cases, watch bands, because of its inherent hydrolysis resistance, anti-fouling, anti-allergic, flame-retardant, safe and environmentally friendly, odorless, and wear-resistant The performance fully meets the high requirements of the electronics industry for leather.
KIREI REZA Silicone Leather-Advanced earphone applications, leather texture, high-quality hand feeling and anti-skin allergy characteristics, long-term use will not be hydrolyzed and flakes, the value of its products surpasses the weather resistance of PU synthetic protein leather, and It is soft and will not change over time for a long time, and will not change the appearance of the product for a period of time!

Silicone leather KIREIREZA

Silicone leather features

Silicone leather is a kind of leather with various colors, textures and feels on the surface of different base fabrics coated with silicone materials. The surface layer is coated with 100% silicone material, and the bottom layer is various base fabrics. KIREI REZA silicone leather material uses polymer organic silicon material. It is an environmentally friendly material, odorless and non-toxic, with excellent weather resistance, electrical insulation, abrasion resistance, oxidation resistance, hydrolysis resistance and aging resistance, high temperature resistance UV resistance, strong compatibility and chemical thermal curing stability, physiologically inert to the human body, biocompatibility, anti-allergic and non-toxic.

KIREI REZA ® silicone leather can replace PVC. It is toxic and cannot be recycled. Environmental protection. It can replace PU synthetic leather. It has poor weather resistance and hydrolysis and chipping after time changes. It can replace leather slaughter animals and post-processing leather solvent processing and environmental protection. Check for heavy metal problems.
KIREI REZA ® silicone leather has the best surface feel and various special textures of the leather. It has an excellent permanent smooth feel and no stickiness. It completely subverts the traditional SILICONE performance effect. The surface feel is not spray-formed and solvent-free. , Precise coating processing and forming can maintain permanent slip and wear resistance.

KIREI REZA ® silicone leather uses environmentally friendly high-performance polymer elastomers, with high temperature resistance -50℃～+250℃, and can be washed at high temperature without coking. KIREI REZA’s superior temperature resistance replaces PVC and PU products for long-term use in high temperature environments.
Because PU has the inevitable problems of hydrolysis, peeling, foaming, and stickiness, KIREI REZA ® silicone leather has excellent hydrolysis resistance and can be applied to more fields than PU leather, such as high-end medical devices, food and kitchenware, automobiles Interior, wearable materials, etc.

Can be combined with various materials processing

1. Colored and special slippery silicone material is coated on precision release material, and reposted and compounded on all kinds of coated fabric materials.
2. The substrate of the covering material can be changed to PET, TPU, PI, PCFILM materials, and different moldings can be changed in IML mode, and it can be combined with various engineering plastics in the mold for high-temperature composite injection molding.
3. Rolled and compounded with TPU hot melt adhesive film to form a roll, and then melted and formed with plastic after punching.
4. Roll composite with 3M double-sided adhesive tape to form a roll, and attach different materials after punching; it can also be an application to increase composite materials.
5. It can be treated with conductive silver paste or sputtering nano-treatment on various cloth surfaces or substrates, which is the best choice for wearable materials.

Silicone leather production process

Prepare the main glue, first add the appropriate proportion of the color paste and mix evenly to color, then add the additives in turn, stir evenly, and vacuum and degas for later use. Set the temperature of the oven and increase the preset temperature. Then determine the pattern to be done, set the width, substrate thickness, silicone thickness and other parameters before turning on the machine.
The adjusted silica gel is evenly coated with a scraper through the feeding port, and the thickness of the glue is controlled and then enters the oven for baking. After the leather comes out of the oven, it is rolled up to complete the production. The baked silicone leather is completely cured and formed, and the silicone surface is closely attached to the base fabric. Nano treatment of silver paste or sputtering process, wearable materials can be applied
The best choice.

Test certification

The safest and environmentally friendly high-performance application materials have passed the SGS testing center

1. Pass the ROHS test and do not contain the content of 6 substances including lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls and polybrominated diphenyl ethers
2. It complies with relevant safety tests and has passed FDA food-grade testing to ensure product safety and environmental protection, and there will be no possibility of high-temperature volatilization and release of low-molecular or harmful substances.
3. In addition, the inspections selected according to Chapter 88 of the United States Pharmacopoeia (USP) and ISO 10993-10 prove that it is non-irritating and non-allergenic in skin contact applications.
4. All other leather-related environmental tests have passed, welcome to inquire

The best high and low temperature resistant high performance application material

1. KIREI REZA Silicone Leather has the characteristics of temperature resistance, can withstand -50℃～+250℃, is a thermosetting material, surpasses all engineering plastics, and can be post-processed.
2. It can pass the test of 65°C and 95%RH in a high temperature and high humidity environment. It is currently the most functional and hand-feeling elastomer temperature resistant material.
