FAQ
Silicone is a synthetic polymer composed of silicon, oxygen, carbon and hydrogen. It is widely used in industrial applications because of its stable chemical properties. They are usually solid and liquid heat-resistant materials and are used in sealants, adhesives, lubricants, pharmaceuticals, cooking utensils, and thermal and electrical insulation. Some common forms include silicone oil, silicone grease, silicone rubber, silicone resin, and silicone filler.
Silicone is a biofriendly and sustainable material that is widely recognized in applications such as medical & healthcare, electronics, automotive, aerospace, industrial assembly, construction, textile, and more.
- Excellent temperature stability (high and low temperature resistance) and weather resistance: Less affected by climate and maintains stable performance under extreme temperatures. Silicone resists rain, ice, UV light, ozone, and is highly resistant to aging, hardening, cracking, and peeling
- UV and ozone resistant: Will not age, harden, crack or peel due to exposure to sunlight, UV/ozone radiation or X-rays
- Chemical resistance: Good resistance to most chemicals (e.g. solvents, oxidizing chemicals, ammonia, etc.) and suitable for use in chemical environments
- Biocompatibility: Harmless to the human body, can contact with human skin without causing allergic reactions, often used in medical and food-grade applications
- Waterproof and anti-slip properties: Has good waterproof properties, allowing electrical equipment to still operate normally when used in humid environments; it has excellent anti-slip properties in a dry state
- Electrical insulation: Silicone rubber, derived from silicate minerals, offers excellent insulating properties, making it a crucial material in the electronics industry. When mixed with conductive fillers, silicone rubber also achieves good conductivity
- Easy to clean: With relatively low surface energy, chemicals and stains are less likely to react with the silicone surface, making it easier to clean. It can be cleaned with alcohol, detergent and other cleaning supplies, and will not react chemically with cleaning supplies
- Softness, elasticity and good shock absorption: Silicone rubber is a highly resilient elastomer with excellent elasticity and flexibility, along with good cushioning and shock absorption properties. It has a soft texture and a pleasant tactile feel
Silicone is a safe and non-toxic synthetic polymer composed of silicon, oxygen, carbon, and hydrogen. It is biocompatible and does not exhibit toxic effects. Many silicone products are food grade and free from harmful substances such as petroleum-based chemicals, BPA, BPS, plasticizers and formaldehyde.
In general, silicone materials remain stable within a temperature range of -40°F to 392°F (-40°C~+200°C) without deterioration. Even when exposed to a broader temperature range of -76°F to 572°F (-60°C~300°C), silicone retains its excellent elasticity. It can withstand temperatures as low as -148°F (-100°C) and as high as approximately 572°F (+300°C).
A wider temperature range can be achieved by adding heat-resistant thermal aging stabilizers or selecting high-temperature resistant silicone rubber.

Conductive carbon or other conductive materials can be added to the silicone, and the silicone can achieve good electrical conductivity and is often used for anti-electromagnetic interference sealing and pressure and environmental sealing. Or you can directly use conductive silicone products to modify the highly insulating silicone rubber into conductive properties. This type of silicone is suitable for producing conductive particles, conductive strips, electrodes, and EMI shielding.

Silicone is biocompatible, chemical-resistant, non-toxic and harmless to the human body. It does not react with most chemicals and does not cause allergic reactions or rejection in the human body. It is suitable for long-term contact with the human body. And silicone’s high temperature resistance can withstand high temperature steam or other methods such as UV disinfection to ensure the hygiene of medical equipment.

Silicone is generally considered safe for food contact. It is non-toxic, contains no harmful chemicals (such as heavy metals, BPA, PFCs, plasticizers and formaldehyde), is chemical resistant and prevents bacterial growth. Food-grade silicone that complies with U.S. FDA regulations makes it a popular choice for a variety of food-related applications.

Food-grade silicone, certified by the US FDA, is commonly used to make pacifiers, silicone cutlery, leak-proof seals and gaskets for containers, as well as conveying mediums in the food processing industry.
Silicone’s exceptional weather resistance and high & low temperatures make it resilient to environmental factors such as UV radiation and high-temperature exposure to outdoor sunlight. This ensures that automotive components maintain their functionality even under extreme conditions. The durability of silicone makes it an ideal choice for automotive parts, including seals, gaskets, and insulation materials.

The full name of LSR is “Liquid Silicone Rubber”. It is a high-purity material that generally contains no impurities, making it suitable for medical and food-grade applications. LSR is a two-component, A and B, which are commonly used in the injection molding process. They are mixed at a ratio of 1:1 and then injected into the mold through LSR injection molding equipment for solidification. It is suitable for applications where rubber is not impractical.
