Silicone
A versatile, high-performance elastomer with excellent heat resistance, cold resistance, and biocompatibility, widely used in products requiring high safety and durability.
What is it
Silicone is a synthetic polymer composed of a silicon-oxygen backbone, possessing unique physicochemical properties. It combines the advantages of both organic and inorganic materials, exhibiting excellent resistance to high and low temperatures (typically ranging from -50°C to 200°C), UV radiation, oxidation, electrical insulation, and good biocompatibility. Silicone can be processed through compression molding, injection molding, or liquid injection molding to create products of various shapes and hardnesses, from soft baby products to durable industrial seals. Its non-toxic, odorless, non-deforming, and easy-to-clean characteristics make it a preferred material for many products with strict safety and functional requirements.
Best for
- Baby Products (pacifiers, teethers)
- Kitchen & Bakeware (spatulas, baking mats)
- Medical Devices (catheters, seals)
- Electronic Device Protectors (phone cases, earbud covers)
- Seals & O-rings
- Custom Promotional Items (keychains, coasters)
Materials
- General Purpose Silicone
- Food-Grade Silicone (FDA / LFGB)
- Medical-Grade Silicone
- High Transparency Silicone
- Conductive Silicone
- Flame Retardant Silicone
Advantages
- Wide Temperature Range: Stable from -50°C to 200°C, with special formulations reaching 300°C.
- Excellent Elasticity & Softness: Wide Shore A hardness range (0-80) to meet diverse application needs.
- Non-toxic & Odorless: Food-grade and medical-grade silicones comply with international standards like FDA, LFGB, safe for human contact.
- High Chemical Stability: UV, oxidation, and ozone resistant, not prone to aging or degradation, ensuring long service life.
- Good Electrical Insulation: An excellent electrical insulator, suitable for electronic components.
- Easy to Clean & Maintain: Non-stick surface, washable or sterilizable, hydrophobic properties.
Limitations
- Higher Cost: 2-5 times more expensive than common plastics (e.g., PP, PVC).
- Relatively Lower Tear Strength: Less tear resistant than some organic rubbers under sharp objects or high stress.
- Prone to Dust & Lint Attraction: Especially on softer silicone surfaces, it can attract ambient particles.
- Poor Solvent Resistance: Less resistant to certain organic solvents (e.g., gasoline, toluene).
- Challenging for Fine Details: Complex fine structures or extremely thin wall thicknesses can be challenging to process.
