What Is The Difference Between PU Leather And Silicone Leather
What is PU leather
- PU artificial leather
PU leather is the abbreviation of Polyurethane (referred to as PU) synthetic leather, and its chemical name is “polyurethane”. PU leather is widely used in the fields of luggage, clothing, shoes, vehicles and furniture decoration, and is welcomed by the market because of its excellent performance and relatively low price.
What is silicone leather
Silicone leather is a new composite material that combines the properties of silica gel and leather. It forms a protective film by coating the surface of the leather with a layer of silicone, thereby retaining the natural texture and beauty of the leather, while enhancing its durability and water resistance.
Z.S.R is a silicone leather manufacturer in China. Z.S.R offer series custom silicone leather provides high design freedom with a wide variety of tailored options in colors, textures, base layer fabric.

How is PU leather and silicone leather made?
PU leather production process
Mixing waste: Polyurethane resin is mixed with pigments, etc., to form a good solid shape.
Coatings: The mixed material is coated on the wet fabric and the polyurethane material is cured through the water tank.
Surface treatment: The coated material is embossed, color adjusted or pattern printed.

Silicone leather production steps
1. Z.S, R worker will mix liquid silicone rubber, color paste, and platinum vulcanizer evenly and coated once. The uncured silicone is made into a film of a certain thickness by a roller, and then the surface of the silicone is completely cured by a hot roller with a specific pattern to obtain a silicone sheet with a textured film;
2.The silicone sheet with a textured film is pressed with the base layer, initially vulcanized, and the textured film is peeled off to obtain a silicone leather semi-finished product with a texture;
3. Hand-feel oil is applied on the texture surface of the silicone leather semi-finished product with a texture, and finally vulcanized.
What is the appearance and texture of PU leather
Appearance: PU leather can imitate the texture and luster of real leather in appearance, showing a similar texture and luster to real leather, giving people a noble and elegant feeling. However, compared to real leather, the texture and gloss of PU leather often appear more artificial, lacking the natural feel and depth of genuine leather .
Texture: Although the texture of PU leather can imitate real leather, its feel is slightly astringent and lacks the soft and elastic characteristics of real leather. When touched, PU leather will give a more blunt feeling, the lack of smooth and natural leather . In addition, PU leather does not have the natural lines and pores of real leather, and the surface is smoother .

What is the appearance and texture of silicone leather
Appearance: The appearance of silicone leather usually presents a smooth, delicate quality, bright colors and is not easy to fade. Its surface is easy to clean, not easy to absorb dust and stains.
Texture: Silicone leather feels soft and smooth, with good elasticity, can bounce back quickly after pressing, without leaving obvious marks. In addition, the texture of silicone leather is strong plasticity, providing designers with rich creative inspiration.
What are the properties of PU leather
Wear resistance and softness: PU leather has excellent wear resistance and softness, which can resist wear and scratching in daily use, while being very comfortable to sit and touch.
Waterproofness: PU leather has a certain waterproof, can resist rain and wet environment, keep dry and comfortable.
Breathability: Although the air permeability of PU leather is relatively poor, in some types, its air permeability can reach 8000-14000g/24h/cm², which is suitable for making waterproof and breathable clothing.
Environmental protection property: PU leather non-toxic, no smell, no pollution, in line with the modern concept of environmental protection.
Workability and appearance: PU leather is easy to process and shape, suitable for a variety of cutting and sewing, smooth surface and high gloss, good appearance .
What are the properties of silicone leather
Environmental protection property: Silicone leather is a new type of environmental protection material, the use of solvent-free technology, non-toxic and tasteless, production and use process are green products. It is mainly made of baby pacifier grade silicone and is environmentally friendly.
Serviceableness: Silicone leather has extremely high wear resistance and scratch resistance, and has been tested by Martindale for up to 50,000 times of wear. In addition, it also has good yellowing resistance and corrosion resistance, can keep the color unchanged within 24 hours, and corrosion resistance is strong. Silicone leather at 100℃ after 72 hours no change, showing excellent aging resistance.
Security: Silicone leather has good biocompatibility, low cytotoxicity, meets the standards in the medical field, and is non-carcinogenic. It has good biocompatibility to the human body, physiological inertia and anticoagulant, will not cause cancer, so it has a wide range of applications in medicine, such as artificial joints and artificial skin.
Waterproof and antifouling: Silicone leather has excellent waterproof performance, the surface is clean after a wipe, and can be dribbled into beads, water molecules can not pass through the surface. It has natural anti-fouling and waterproofing for common stains and can be removed with a wipe.
Weather fastness: Silicone leather exhibits excellent resistance to hydrolysis and light. After more than 10 weeks of testing in a high temperature and humidity environment (such as 70℃ and 95% humidity), the leather surface does not appear sticky, shiny or brittle. In addition, silicone leather is excellent in resistance to sunlight fading, and can still maintain stability and color unchanged after ten years of exposure.
